<strong>Measur<strong>in</strong>g</strong> Technology<br />

<strong>in</strong> the Steel Industry<br />



Development of new <strong>Measur<strong>in</strong>g</strong><br />

<strong>Systems</strong> Cont<strong>in</strong>uity at <strong>IMS</strong><br />

Users expect not only excellent process<strong>in</strong>g properties<br />

and usage characteristics, but also high lifetime, longterm<br />

value and high quality from modern materials. Only<br />

technically superior products – steel of the highest precision<br />

– can survive competition on the market.<br />

Thanks to constant improvements <strong>in</strong> strength and deformability,<br />

steel can be produced <strong>in</strong> ever th<strong>in</strong>ner dimensions.<br />

And that with ever tighter dimensional tolerances.<br />

The f<strong>in</strong>ish<strong>in</strong>g coat<strong>in</strong>gs on steel are also grow<strong>in</strong>g th<strong>in</strong>ner<br />

and more effective with ever more complex layer structures.<br />

The material behaviour and mechanical dimensions<br />

are virtually constant along the complete length and width<br />

of a rolled steel strip.<br />

To meet these high demands, the steel <strong>in</strong>dustry needs<br />

<strong>in</strong>novative, high-precision onl<strong>in</strong>e measur<strong>in</strong>g technologies<br />

with <strong>in</strong>telligent quality management and analysis systems.<br />

The measur<strong>in</strong>g processes and technologies described<br />

<strong>in</strong> this brochure are, together with optimised process<br />

models, precision control loops and appropriate<br />

regulat<strong>in</strong>g elements, the prime prerequisites for achiev<strong>in</strong>g<br />

the high level of product quality required from high-speed<br />

cont<strong>in</strong>uous production processes. Maximum availability<br />

and reproducible measur<strong>in</strong>g results ensure the high<br />

process stability required for cont<strong>in</strong>uous operation.<br />

<strong>IMS</strong> works tirelessly develop<strong>in</strong>g measur<strong>in</strong>g systems for<br />

the improve ment of thickness, profile, width and flatness<br />

<strong>in</strong> roll<strong>in</strong>g mills.<br />

In parallel with technical devel opments for equipment<br />

improvement such as:<br />

• hydraulic adjustment<br />

• fast work roll bend<strong>in</strong>g systems<br />

• slide rolls <strong>in</strong> conjunction with mathematical models<br />

for roll force, profile and flatness<br />

<strong>IMS</strong> measur<strong>in</strong>g systems also undergo cont<strong>in</strong>uous optimisation<br />

<strong>in</strong> terms of accuracy, resolution and dynamic<br />

performance.<br />

Output and profitability <strong>in</strong> the production of black plate,<br />

t<strong>in</strong> plate and sta<strong>in</strong>less steel depend on, among other<br />

factors, compliance with the tolerances prescribed for<br />

thickness, thickness profile, width and flatness.<br />

Today <strong>IMS</strong> offers multifunctional measur<strong>in</strong>g systems for<br />

cont<strong>in</strong>uous measurement of the follow<strong>in</strong>g quality criteria<br />

<strong>in</strong> cold strip mills:<br />

• thickness<br />

• thickness profile<br />

• thickness edge profile<br />

• width<br />

• holes<br />

• p<strong>in</strong>holes<br />

• edge cracks<br />

• phase content<br />

• <strong>in</strong>ternal <strong>in</strong>clusions / shell defects<br />

• coat layers<br />

• flatness<br />

• evenness<br />

The ideal is a product with constant thickness and width,<br />

and a constant prescribed profile along the complete<br />

length of the coil – a product without flatness errors and<br />

with m<strong>in</strong>imised residual stresses.<br />

• 2D surface <strong>in</strong>spection<br />

• strip tension / web tension<br />

• speed<br />

• length<br />

Thickness Edge Drop<br />

<strong>Cold</strong> roll<strong>in</strong>g tandem mills are usually built as cont<strong>in</strong>uous<br />

l<strong>in</strong>es with direct connection to pickl<strong>in</strong>g l<strong>in</strong>es.<br />

In the pickl<strong>in</strong>g plant the steel strip is freed of scale completely<br />

by acids. After clean<strong>in</strong>g of the surface to remove<br />

the acid, the strip runs through a dryer. A levell<strong>in</strong>g unit<br />

comes last and ensures the strip is absolutely flat.<br />

When equipped appropriately, new production processes<br />

<strong>in</strong> tandem mills allow the manufacture of strips with<br />

constant thickness over the complete length and width<br />

of the strip.<br />

When extremely th<strong>in</strong> strips are cold-rolled, the strip thickness<br />

drops markedly <strong>in</strong> the edge area together with flatness<br />

errors.<br />

With mill structures such as<br />

• 6-high or 4-high stands<br />

• specially ground and adjustable work and<br />

<strong>in</strong>termediate rolls<br />

• roll bend<strong>in</strong>g systems<br />

• adapted cool<strong>in</strong>g units<br />

For optimum control of the process parameters and<br />

quality assurance, the follow<strong>in</strong>g measur<strong>in</strong>g systems are<br />

<strong>in</strong>tegrated <strong>in</strong> a comb<strong>in</strong>ed pickl<strong>in</strong>g/tandem l<strong>in</strong>e:<br />

• strip thickness gauge (strip centrel<strong>in</strong>e measurement<br />

or with cross profile function) at the entry to the<br />

pickl<strong>in</strong>g section<br />

• scale coat<strong>in</strong>g gauge before and after the pickl<strong>in</strong>g<br />

section<br />

• one or multi-head strip thickness gauge with cross<br />

profile function at the exit from the pickl<strong>in</strong>g section<br />

• strip width gauge beh<strong>in</strong>d the trimm<strong>in</strong>g shear at the<br />

exit from the pickl<strong>in</strong>g section with optional add-on<br />

for hole and edge crack detection<br />

• strip thickness gauges for strip centrel<strong>in</strong>e measurement<br />

beh<strong>in</strong>d the <strong>in</strong>dividual stands <strong>in</strong> the tandem l<strong>in</strong>e<br />

• edge drop measur<strong>in</strong>g system beh<strong>in</strong>d the first and<br />

last stand <strong>in</strong> the tandem l<strong>in</strong>e<br />

• strip width gauges at the exit from the tandem l<strong>in</strong>e<br />

<strong>in</strong>clud<strong>in</strong>g hole and edge crack detector<br />

• shapemeter rolls beh<strong>in</strong>d the first and last stand <strong>in</strong><br />

the tandem l<strong>in</strong>e<br />

• laser speed gauges for strip thickness and mass<br />

flow control before and after the first and last stand,<br />

<strong>in</strong>tegrated <strong>in</strong> the strip thickness gauges or as standalone<br />

systems<br />

• strip tension gauge before or after the stand<br />

Revers<strong>in</strong>g <strong>Cold</strong> Mill<br />

Cont<strong>in</strong>uous Anneal<strong>in</strong>g L<strong>in</strong>e<br />

Sk<strong>in</strong> Pass Mill<br />

F<strong>in</strong>ish<strong>in</strong>g L<strong>in</strong>es<br />

A one-stand revers<strong>in</strong>g cold mill usually consists of three<br />

coilers and a mill stand. Two coilers are needed to w<strong>in</strong>d<br />

and unw<strong>in</strong>d the runn<strong>in</strong>g strip, while the third coiler is used<br />

to prepare the next strip. The material is rolled to its f<strong>in</strong>al<br />

thickness <strong>in</strong> multiple passes.<br />

Four-high, six-high and multiple-roll mill stands are used<br />

for cold roll<strong>in</strong>g. The more rolls that are used, the greater<br />

the possibilities to <strong>in</strong>fluence the material, especially regard<strong>in</strong>g<br />

strip geometry.<br />

Multiple-roll mill stands conta<strong>in</strong> up to 20 rolls of various<br />

diameters arranged symmetrically. Us<strong>in</strong>g small work rolls,<br />

it is possible to process sta<strong>in</strong>less steel that is usually<br />

difficult to form.<br />

In cold roll<strong>in</strong>g, the reel tension supports the process of<br />

thickness reduction.<br />

The follow<strong>in</strong>g measur<strong>in</strong>g systems are used <strong>in</strong> a revers<strong>in</strong>g<br />

cold mill:<br />

• one or multi-head strip thickness gauges (strip<br />

centrel<strong>in</strong>e measurement or with cross profile function)<br />

before and after the mill stand<br />

• Laser speed gauges for strip thickness and mass<br />

flow control before and after the mill stand, <strong>in</strong>tegrated<br />

<strong>in</strong> the strip thickness gauges or as stand-alone<br />

systems<br />

The material hardens dur<strong>in</strong>g cold roll<strong>in</strong>g and therefore<br />

needs to undergo anneal<strong>in</strong>g treatment before further<br />

process<strong>in</strong>g. Heat<strong>in</strong>g the steel <strong>in</strong> an anneal<strong>in</strong>g furnace<br />

changes its solidification structure and its surface<br />

structure.<br />

The process of cont<strong>in</strong>uous anneal<strong>in</strong>g comprises the steps<br />

of strip clean<strong>in</strong>g, recrystallisation anneal<strong>in</strong>g, sk<strong>in</strong> pass<br />

roll<strong>in</strong>g and trimm<strong>in</strong>g.<br />

The follow<strong>in</strong>g measur<strong>in</strong>g devices are used at cont<strong>in</strong>uous<br />

anneal<strong>in</strong>g furnaces:<br />

• strip thickness gauges (only for strip centrel<strong>in</strong>e<br />

measurement or with cross profile function) at the<br />

entry to and exit from the cont<strong>in</strong>uous anneal<strong>in</strong>g l<strong>in</strong>e<br />

• strip width gauges at the entry to and exit from the<br />

cont<strong>in</strong>uous anneal<strong>in</strong>g l<strong>in</strong>e with hole and edge crack<br />

detectors as optional extensions<br />

• strip tension measur<strong>in</strong>g devices <strong>in</strong> all stages of the<br />

production process<br />

• residual dirt measur<strong>in</strong>g devices (ellipsometry<br />

measur<strong>in</strong>g devices)<br />

Reroll<strong>in</strong>g of annealed cold strip improves strip flatness<br />

and produces a def<strong>in</strong>ed surface topography (surface<br />

roughness). At the same time, sk<strong>in</strong> pass roll<strong>in</strong>g achieves a<br />

def<strong>in</strong>ed yield strength needed for subsequent deep draw<strong>in</strong>g<br />

processes, e.g. <strong>in</strong> the production of beverage cans.<br />

Sk<strong>in</strong> pass mills have one or two stands.<br />

The follow<strong>in</strong>g measur<strong>in</strong>g systems are used <strong>in</strong> a sk<strong>in</strong> pass<br />

mill:<br />

• strip thickness gauges (only for strip centrel<strong>in</strong>e<br />

measurement or with cross profile function) before<br />

and after the sk<strong>in</strong> pass mill<br />

• strip thickness gauge as stand-alone device or with<br />

<strong>in</strong>tegrated laser speed gauge for strip thickness and<br />

mass flow control before and after the sk<strong>in</strong> pass mill<br />

• shapemeter rolls before and after the last sk<strong>in</strong> pass<br />

mill<br />

• strip width gauge at the exit from the sk<strong>in</strong> pass mill<br />

with hole and edge crack detectors as optional<br />

extensions<br />

• residual dirt measur<strong>in</strong>g devices with ellipsometry<br />

measur<strong>in</strong>g heads at the exit from the sk<strong>in</strong> pass mill<br />

• strip tension gauge before and after the stand<br />

In the f<strong>in</strong>ish<strong>in</strong>g l<strong>in</strong>es (recoil<strong>in</strong>g, <strong>in</strong>spection system, cutto-length<br />

and slitt<strong>in</strong>g l<strong>in</strong>es) the strips are <strong>in</strong>spected and<br />

cut to size.<br />

The follow<strong>in</strong>g measur<strong>in</strong>g systems are used for quality<br />

control:<br />

• strip thickness gauge (strip centrel<strong>in</strong>e measurement<br />

or with cross profile function) at the entry or exit<br />

(depend<strong>in</strong>g on the type of equipment)<br />

• strip width gauges at the entry or exit (depend<strong>in</strong>g<br />

on the type of equipment) with hole and edge crack<br />

detectors as optional extensions<br />

• strip tension gauge<br />

• Shapemeter rolls before the coiler and decoiler<br />

• strip tension measur<strong>in</strong>g system before and after the<br />

stand.<br />

Thickness <strong>Measur<strong>in</strong>g</strong> <strong>Systems</strong><br />

Modern production and <strong>in</strong>spection l<strong>in</strong>es run at high<br />

speeds and with<strong>in</strong> tight tolerances. Quality and profitability<br />

depend decisively on compliance with the thickness<br />

tolerance range.<br />

<strong>IMS</strong> thickness measur<strong>in</strong>g systems measure the thickness<br />

of material precisely on the centrel<strong>in</strong>e – onl<strong>in</strong>e and without<br />

mak<strong>in</strong>g contact with the material.<br />

Apart from the fixed position on the centrel<strong>in</strong>e, the<br />

thickness gauge can also be equipped for thickness<br />

profile measurements. In this case the measur<strong>in</strong>g frame<br />

traverses cont<strong>in</strong>uously between the two opposite ends<br />

of the material.<br />

Performance features of our measur<strong>in</strong>g systems:<br />

• Non-contact, cont<strong>in</strong>uous and fast measurement of<br />

parameters <strong>in</strong> real time with the highest possible<br />

accuracy.<br />

• The gauges are adapted <strong>in</strong>dividually to the particular<br />

place of <strong>in</strong>stallation and are universal <strong>in</strong> use.<br />

• Thickness measur<strong>in</strong>g devices can be equipped additionally<br />

with length and speed measur<strong>in</strong>g devices.<br />

The measured values are needed to control thickness <strong>in</strong><br />

order to obta<strong>in</strong> a specific and constant thickness over the<br />

length of the material. The thickness measur<strong>in</strong>g systems<br />

are used <strong>in</strong> coat<strong>in</strong>g l<strong>in</strong>es for f<strong>in</strong>al control of the product<br />

before delivery.<br />

<strong>Measur<strong>in</strong>g</strong> Pr<strong>in</strong>ciple<br />

<strong>IMS</strong> thickness measur<strong>in</strong>g systems work by the pr<strong>in</strong>ciple<br />

of material irradiation. Ionis<strong>in</strong>g radiation emitted by a radiation<br />

source passes through the object and, weakened<br />

by the thickness of the material, arrives at a detector<br />

(ionisation chamber) specially developed by <strong>IMS</strong>. <strong>Measur<strong>in</strong>g</strong><br />

transducers <strong>in</strong> the measur<strong>in</strong>g<br />

frame process the measured values<br />

for further use.<br />

<strong>Measur<strong>in</strong>g</strong> systems <strong>in</strong> cold roll<strong>in</strong>g<br />

mills are equipped today with<br />

advanced x-ray technology.<br />

The advantage of this<br />

radiation energy compared<br />

to conventional isotope<br />

radiation is a much bigger<br />

signal-to-noise ratio.<br />

The x-ray systems work with a constant energy level<br />

optimised to the respective application over the complete<br />

measur<strong>in</strong>g range. This results <strong>in</strong> the follow<strong>in</strong>g advantages:<br />

• one l<strong>in</strong>earisation curve over the complete measur<strong>in</strong>g<br />

range.<br />

• cont<strong>in</strong>uous measurements without additional<br />

switch<strong>in</strong>g functions and range standardisations.<br />

• no delays from thermal transient responses of the<br />

x-ray tubes because there is no change <strong>in</strong> the high<br />

voltage<br />

• under constant conditions of use, x-ray tubes offer<br />

high lifetimes<br />

• alloy compensations do not need to be adapted to<br />

chang<strong>in</strong>g energy ranges.<br />

Compensation of disturbances:<br />

• Alloy changes by mathematical processes <strong>in</strong> dependence<br />

on chemical analysis and quality.<br />

• Contam<strong>in</strong>ation <strong>in</strong> the beam path by mathematical<br />

processes dur<strong>in</strong>g radiation standardisation.<br />

System Description<br />

One to four detectors are used. Every detector output<br />

signal of a measur<strong>in</strong>g head is treated <strong>in</strong>dividually as <strong>in</strong>dependent<br />

thickness measur<strong>in</strong>g channel. A plausibility<br />

check is carried out cont<strong>in</strong>uously both dur<strong>in</strong>g measurement<br />

and dur<strong>in</strong>g the radiation standardisation process.<br />

Edge Drop measur<strong>in</strong>g frame<br />

Material thickness is measured <strong>in</strong> the centre and at the<br />

edges of strip by a three-head measur<strong>in</strong>g frame equipped<br />

with three x-ray tubes, each with a separate detector unit.<br />

The centrel<strong>in</strong>e detector unit has two to four detectors<br />

and the two detector units on the outside have an array<br />

of four to 22 detectors depend<strong>in</strong>g on the application.<br />

Ionisation chambers are used exclusively as detectors.<br />

The number of detectors is governed by the requirements<br />

of our customers and also dependent on the strip widths.<br />

Applications with more detectors are possible.<br />

The two measur<strong>in</strong>g heads at the edges are positioned<br />

<strong>in</strong> dependence on the width of the strip. In the case<br />

of horizontal strip roam<strong>in</strong>g dur<strong>in</strong>g measurement the<br />

measur<strong>in</strong>g heads automatically follow the strip.<br />

The strip width and strip position are determ<strong>in</strong>ed from the<br />

measur<strong>in</strong>g signals of the <strong>in</strong>dividual measur<strong>in</strong>g channels<br />

<strong>in</strong> the edge area.<br />

The complete measur<strong>in</strong>g frame is fixed <strong>in</strong> measur<strong>in</strong>g position<br />

with the help of a lock<strong>in</strong>g device so that a repeatable<br />

measur<strong>in</strong>g position is ensured at all times.<br />

The three-head measur<strong>in</strong>g system measures the follow<strong>in</strong>g<br />

parameters:<br />

• strip thickness <strong>in</strong> the centre of the strip<br />

• edge thickness<br />

• wedge, crown<br />

• thickness profile<br />

• strip width<br />

• positions of the strip edges<br />



Three-Head Thickness Profile<br />

and Strip Edge Profile <strong>Measur<strong>in</strong>g</strong><br />

System (Edge Drop)<br />

The edge drop measur<strong>in</strong>g system also measures the edge<br />

drop at the edges of the material.<br />

The three measur<strong>in</strong>g heads are arranged on a l<strong>in</strong>e <strong>in</strong><br />

cross profile direction. Due to mechanical limitations,<br />

there is an area <strong>in</strong> the centre of the strip that cannot be<br />

measured. Thickness cross profile measurement is not<br />

possible <strong>in</strong> this area.<br />

In emergency operation, i.e. when the centrel<strong>in</strong>e gauge<br />

fails, the opera tor-side measur<strong>in</strong>g head is driven to its end<br />

position <strong>in</strong> drive-side direction. The measur<strong>in</strong>g frame is<br />

then driven towards the drive side until the operator-side<br />

edge measur<strong>in</strong>g head is positioned <strong>in</strong> the centre of the<br />

strip.<br />

Strip flatness errors lead to measur<strong>in</strong>g errors, especially<br />

<strong>in</strong> multi-channel systems with <strong>in</strong>cl<strong>in</strong>ed chambers. Us<strong>in</strong>g<br />

the LasCon system, consist<strong>in</strong>g of two lasers and a CCD<br />

area scan camera, strip flatness errors can be detected<br />

and used as correction values for the edge drop system.<br />

For this the lasers project two l<strong>in</strong>es on to the strip, the<br />

positions and shapes of which are then detected by the<br />

camera.<br />

Thickness measur<strong>in</strong>g frame<br />




Two Head Thickness Profile<br />

<strong>Measur<strong>in</strong>g</strong> System<br />



Tw<strong>in</strong>-Set Thickness and<br />

Profile <strong>Measur<strong>in</strong>g</strong> System<br />

A two-head thickness cross profile measur<strong>in</strong>g frame consists<br />

of a C-frame with either two mobile measur<strong>in</strong>g heads<br />

that can be moved separately of each other or a fixed<br />

centrel<strong>in</strong>e measur<strong>in</strong>g head and a mobile measur<strong>in</strong>g head.<br />

The mobile measur<strong>in</strong>g heads can record the complete<br />

thickness cross profile over the strip width.<br />

In normal mill operations one measur<strong>in</strong>g head stays <strong>in</strong> the<br />

centre of the strip, while the other traverses across the<br />

complete strip width. The difference between the centre<br />

signal and the signal of the travers<strong>in</strong>g measur<strong>in</strong>g head<br />

is formed cont<strong>in</strong>uously dur<strong>in</strong>g the profile traverse. Us<strong>in</strong>g<br />

this <strong>in</strong>formation, the length profile <strong>in</strong>fluence is corrected<br />

automatically dur<strong>in</strong>g the roll<strong>in</strong>g process.<br />

When the strip is stationary, both measur<strong>in</strong>g heads can<br />

be moved from the strip centre to the strip edges, one<br />

to the operator side and the other to the drive side to<br />

reduce the scann<strong>in</strong>g time.<br />

The width and strip position are determ<strong>in</strong>ed from the data<br />

acquired by the scann<strong>in</strong>g measur<strong>in</strong>g head. The C-frame<br />

is locked <strong>in</strong> measur<strong>in</strong>g position (mill stand centre) so that<br />

a repeatable position is ensured at all times<br />

The two-head measur<strong>in</strong>g system measures the follow<strong>in</strong>g<br />

parameters:<br />

• strip thickness <strong>in</strong> the centre of the strip<br />

• edge thickness<br />

• edge drop<br />

• wedge, crown<br />

• thickness profile<br />

• strip width<br />

• positions of the strip edges<br />

In emergency operation, i.e. when the centrel<strong>in</strong>e gauge<br />

fails, the mobile measur<strong>in</strong>g head is driven to strip centrel<strong>in</strong>e<br />

position and takes over all functions of the strip<br />

centrel<strong>in</strong>e gauge.<br />

Various cross profile and movement programs can<br />

Tw<strong>in</strong>set thickness and profile measur<strong>in</strong>g frame<br />

Two-head thickness<br />

profile measur<strong>in</strong>g frame<br />

The Tw<strong>in</strong>set profile measurement consists of two separate<br />

C-frames. At the entry side of the Mill, one C-frame<br />

measures the centre l<strong>in</strong>e thickness of the strip. A second,<br />

scann<strong>in</strong>g C-frame located at the exit side of the Mill provides<br />

cross strip profile data as it scans backwards and<br />

forwards across the strip.<br />

Dur<strong>in</strong>g measurement this C-frame moves cont<strong>in</strong>uously<br />

from one edge of the material to the other. As a result<br />

the profile of the material is measured across the width<br />

of the material. The travers<strong>in</strong>g thickness gauge can also<br />

be used <strong>in</strong> stationary mode to measure the thickness on<br />

the centrel<strong>in</strong>e.<br />

The measur<strong>in</strong>g system measures the follow<strong>in</strong>g<br />

parameters:<br />

• centre thickness<br />

• thickness profile,<br />

wedge and crown<br />

The profile is calculated from the difference between the<br />

strip centre l<strong>in</strong>e thickness at the mill entry and the strip<br />

profile at the mill exit. At the same time the distance<br />

between the two spatially separate measur<strong>in</strong>g po<strong>in</strong>ts is<br />

corrected.<br />

The tw<strong>in</strong>set system is a simple method of measurement<br />

with which correct thickness profile measurement is possible<br />

under the follow<strong>in</strong>g conditions:<br />

• The tw<strong>in</strong>set profile measurement provides an <strong>in</strong>expensive<br />

method of measur<strong>in</strong>g correct strip profile<br />

provided that the strip rema<strong>in</strong>s flat on the roll table<br />

(i.e. at the correct passl<strong>in</strong>e). Any degree of non-flatness<br />

<strong>in</strong> the strip dur<strong>in</strong>g scann<strong>in</strong>g will lead to <strong>in</strong>correct<br />

profile meas urement.<br />

• The number of measured thickness cross profiles<br />

must be limited to a few measurements per coil<br />

dependent on the length and width of the material<br />

and on the strip speed.<br />

Due to the relatively long control loop response time,<br />

onl<strong>in</strong>e profile control is not feasible. And, under certa<strong>in</strong><br />

circumstances, it is possible that changes <strong>in</strong> the profile –<br />

and therefore changes <strong>in</strong> the wedge and crown over the<br />

coil length – will not be measured accurately.<br />

Depend<strong>in</strong>g on the radiation beam geometry, one or two<br />

detectors are arranged <strong>in</strong> the strip length direction <strong>in</strong><br />

order to achieve the required measur<strong>in</strong>g resolution, i.e.<br />

the smallest measured width <strong>in</strong> the cross strip direction.<br />

Force Measurement <strong>Systems</strong><br />

Modern production equipment is designed for high productivity<br />

and quality. To achieve these aims, it is of critical<br />

importance that all production parameters are complied<br />

with exactly.<br />

<strong>IMS</strong> force measurement systems are used for a multitude<br />

of purposes, e.g. to measure strip and web tension.<br />

They are characterised by high precision, reliability and<br />

durability. Thanks to modern fabrication techniques, it<br />

is possible to manufacture special solutions for application-specific<br />

force transducers.<br />

It is also possible to replace older systems step by step.<br />

In this case the measur<strong>in</strong>g electronics are replaced <strong>in</strong> the<br />

first phase and later then also the force transducers. This<br />

procedure reduces the current cost of <strong>in</strong>vestment and<br />

delivers reliability <strong>in</strong> the event of a failure.<br />

Precise – Dynamic –<br />

High-Speed Response<br />

Our force transducers boast high dynamics, precision<br />

and fast reaction to force changes. They are also very<br />

easy to put <strong>in</strong>to service. Integrated calibration signals<br />

make a reference measurement on site unnecessary. The<br />

high overload capacity – standard up to eight times the<br />

nom<strong>in</strong>al load and optionally up to 20 times the nom<strong>in</strong>al<br />

load – enables use <strong>in</strong> many fields of application.<br />

Shapemeter Roll<br />

Shapemeter rolls to measure strip flatness are usually<br />

employed <strong>in</strong> roll<strong>in</strong>g mills beh<strong>in</strong>d the first and last stand<br />

(<strong>in</strong> f<strong>in</strong>ish<strong>in</strong>g l<strong>in</strong>es beh<strong>in</strong>d the sk<strong>in</strong> pass mill) for optimal<br />

flatness regulation and to ensure process stability.<br />

The distribution of the tensile forces – <strong>in</strong> other words<br />

the differences <strong>in</strong> strip length tensions result<strong>in</strong>g from<br />

differently directed strip fibres – is measured across the<br />

strip width and sent to the strip flatness control system.<br />

The force is measured by robust and high-strength quartz<br />

force sensors <strong>in</strong>tegrated <strong>in</strong> the roller bodies. In order<br />

for the flatness control system to respond quickly, the<br />

measured values must be accurate and sent to the control<br />

system immediately after the strip has passed the roll.<br />

The shapemeter rolls fulfil these requirements.<br />

Depend<strong>in</strong>g on the application <strong>in</strong> question, the shapemeter<br />

roll can be constructed with suitable measurement zones,<br />

measurement zone width and roll surface.<br />

Due to the optical rotary transmitter, the roll electronics<br />

are completely ma<strong>in</strong>tenance-free.<br />

Optical measur<strong>in</strong>g systems from <strong>IMS</strong> are used <strong>in</strong> various<br />

production l<strong>in</strong>es – for example <strong>in</strong> tandem l<strong>in</strong>es, pickl<strong>in</strong>g,<br />

coat<strong>in</strong>g, <strong>in</strong>spection and recoil<strong>in</strong>g l<strong>in</strong>es as well as <strong>in</strong> slitt<strong>in</strong>g<br />

and cut-to-length l<strong>in</strong>es.<br />

In production l<strong>in</strong>es <strong>IMS</strong> systems measure the width,<br />

centrel<strong>in</strong>e deviation, strip contour, cross crown as well<br />

as the position of strips, and <strong>in</strong> slitt<strong>in</strong>g l<strong>in</strong>es, for example,<br />

every s<strong>in</strong>gle strip. They detect and classify edge cracks<br />

and holes.<br />

The optical measur<strong>in</strong>g system basically consists of a<br />

“camera beam” above the strip and a “backlight beam”<br />

underneath the strip. The camera beam detects the <strong>in</strong>frared<br />

radiation emitted from the backlight beam. Us<strong>in</strong>g<br />

an <strong>in</strong>novative camera cluster technology, 50 cameras<br />

are used per 1,000 mm <strong>in</strong>spection length to perform the<br />

measur<strong>in</strong>g tasks, thus ensur<strong>in</strong>g extremely high resolution.<br />

The backlight is based on LED technology and guarantees<br />

very long life. Influences from extraneous light are<br />

suppressed by use of special spectral ranges of the LEDs.<br />

The measur<strong>in</strong>g system works without electro-mechanical<br />

mov<strong>in</strong>g parts and is thus ma<strong>in</strong>tenance-free.<br />

The distance between camera hous<strong>in</strong>g and strip material<br />

can be varied from very big to very small. The system<br />

can be <strong>in</strong>tegrated <strong>in</strong> a production l<strong>in</strong>e, where it requires<br />

a m<strong>in</strong>imum of space, or <strong>in</strong> an exist<strong>in</strong>g <strong>IMS</strong> measur<strong>in</strong>g<br />

system. Thanks to its modular design, the system can<br />

be extended to any strip width required.<br />

Strip Width <strong>Measur<strong>in</strong>g</strong> System<br />

Compared to conventional travers<strong>in</strong>g camera systems,<br />

the system achieves higher accuracy. The strip edges<br />

are detected stereoscopically. Vertical movements <strong>in</strong> the<br />

strip therefore have no <strong>in</strong>fluence on measur<strong>in</strong>g accuracy.<br />

The system can optionally be extended by hole detector<br />

and edge crack and contour measur<strong>in</strong>g systems. All<br />

measurement tasks are performed <strong>in</strong> the measur<strong>in</strong>g beam<br />

and communicated via <strong>in</strong>terfaces.<br />

Hole Detector<br />

The hole detector detects holes with a diameter of a few<br />

hundred micrometres and more at high strip speeds. The<br />

system enables exact localisation of the defects over the<br />

strip width and strip length and also provides <strong>in</strong>formation<br />

on the size and position of the holes. In contrast to the<br />

p<strong>in</strong>hole detector, images of the flaws are also produced.<br />

The system can optionally be extended by edge crack,<br />

strip width and contour measur<strong>in</strong>g systems. All measured<br />

values are determ<strong>in</strong>ed <strong>in</strong> the measur<strong>in</strong>g beam and can<br />

be visualised on a PC if wanted.<br />

P<strong>in</strong>hole Detector<br />

P<strong>in</strong>holes with a diameter of a few micrometres are a<br />

critical quality feature particularly <strong>in</strong> the production of<br />

alum<strong>in</strong>ium and t<strong>in</strong> plate packag<strong>in</strong>g material. The ma<strong>in</strong>tenance-free<br />

p<strong>in</strong>hole detector detects the size of the hole<br />

together with its exact position <strong>in</strong> transverse and longitud<strong>in</strong>al<br />

direction. The system can optionally be extended<br />

by edge crack and strip width measur<strong>in</strong>g systems.<br />

Edge Crack <strong>Measur<strong>in</strong>g</strong> System<br />

Shapemeter roll<br />

with calibration device<br />

Edge crack <strong>in</strong>formation is needed for optimum trimm<strong>in</strong>g<br />

and for quality control. The measur<strong>in</strong>g beam detects the<br />

depth, length and position of cracks <strong>in</strong> the strip. Photos<br />

of the defects are also generated. The system can optionally<br />

be extended by: hole detector and strip width<br />

and contour measur<strong>in</strong>g systems.<br />

Ellipsometry <strong>Measur<strong>in</strong>g</strong> System<br />

Break<strong>in</strong>g Barriers<br />

through Optimisation<br />



The ellipsometry measur<strong>in</strong>g method is based on the<br />

measurement and evaluation of polarisation properties.<br />

For this, l<strong>in</strong>ear polarised laser light is directed at the<br />

material at a def<strong>in</strong>ed angle. The light passes through<br />

the layer that is to be measured and is reflected by the<br />

substrate. While the laser light illum<strong>in</strong>ates the layer, the<br />

polarisation properties change. Us<strong>in</strong>g suitable detectors,<br />

these changes are measured and converted by a calibration<br />

to a layer thickness or a mass per area unit value.<br />

The method allows non-contact and non-destructive<br />

measurement of layers rang<strong>in</strong>g from 0 to 100 nm. Us<strong>in</strong>g<br />

a suitable optical system, the passive angle tolerance is<br />

fixed at ± 0.5 ° and the passive distance tolerance at a<br />

measur<strong>in</strong>g distance of 48 mm at ± 0.6 mm. If the distance<br />

changes by up to ± 4 mm, a servomechanism <strong>in</strong>tervenes<br />

and repositions the optical system.<br />

The optical system and signal process<strong>in</strong>g electronics<br />

are housed <strong>in</strong> a robust alum<strong>in</strong>ium hous<strong>in</strong>g and protected<br />

aga<strong>in</strong>st external <strong>in</strong>fluences. The measur<strong>in</strong>g head needs<br />

a 24V power supply, a supply of air to keep the optical<br />

system clean and a network connection to the control<br />

system. The measur<strong>in</strong>g system boasts high sensitivity<br />

and a high measur<strong>in</strong>g rate and is suitable for <strong>in</strong>dustrial<br />

processes with high material speeds up to 800 m/m<strong>in</strong>.<br />

Calibration is more or less completely automated and<br />

requires little manual work.<br />

<strong>IMS</strong> measur<strong>in</strong>g systems are used <strong>in</strong> roll<strong>in</strong>g mills <strong>in</strong> the<br />

harshest of environmental conditions and are renowned<br />

for their very high availability.<br />

By us<strong>in</strong>g modern X-ray technology and fast, high-precision<br />

detectors, <strong>IMS</strong> measur<strong>in</strong>g systems achieve extremely<br />

high measur<strong>in</strong>g accuracies at very low measur<strong>in</strong>g time<br />

constants, establish<strong>in</strong>g their rightful place <strong>in</strong> the range of<br />

hightech systems used <strong>in</strong> <strong>in</strong>dustrial metrology.<br />

Together with optimised process models and precision<br />

control technology, the measur<strong>in</strong>g meth ods and technologies<br />

described are essential pre-requisites <strong>in</strong> the<br />

atta<strong>in</strong>ment of the high level product quality required <strong>in</strong><br />

high-speed cont<strong>in</strong>uous production processes. An <strong>in</strong>ter-plant<br />

quality management system enables <strong>in</strong>ter-process<br />

optimisation.<br />

New goals are achieved through permanent ongo<strong>in</strong>g<br />

development. What is technically feasible today may be<br />

accepted as every day practice tomorrow, and possibly<br />

replaced completely by new technologies the day after.<br />

You profit from our experience!<br />

Due to the high resolution of the measur<strong>in</strong>g method, it is<br />

possible to measure even the smallest of coat changes<br />

of various types. The measur<strong>in</strong>g system therefore consists<br />

of a comb<strong>in</strong>ation of a base measurement before the<br />

coat<strong>in</strong>g process and a ma<strong>in</strong> measurement. In this way<br />

it is possible to m<strong>in</strong>imise the <strong>in</strong>fluence of disturbances<br />

from upstream processes.<br />

The system is able to measure both relative coat<strong>in</strong>g<br />

changes as well as absolute values on various base materials<br />

such as steel, sta<strong>in</strong>less steel, alum<strong>in</strong>ium, copper<br />

and brass.<br />

The applications for this method lie <strong>in</strong> the measurement of<br />

organic and <strong>in</strong>organic coat<strong>in</strong>gs (e.g. oils, alternative oil<strong>in</strong>g<br />

on t<strong>in</strong>plate), the determ<strong>in</strong>ation of phosphate layers and <strong>in</strong><br />

measurement of oxide layers. The measur<strong>in</strong>g system is<br />

also suitable for measurement of residual contam<strong>in</strong>ation<br />

(e.g. <strong>in</strong> temper mills).<br />

„Responsibility means to<br />

blame yourself for the lack of<br />

susta<strong>in</strong>ability.“<br />

(Ronny Boch, geologist, free author)<br />

Conservation of resources<br />

through precision out of<br />

passion and quality out of<br />

conviction<br />

We at <strong>IMS</strong>, as the world market leader for measur<strong>in</strong>g<br />

systems, are aware of our social responsibility of susta<strong>in</strong>able<br />

management!<br />

To give our customers, suppliers and stakeholders a<br />

transparent <strong>in</strong>sight <strong>in</strong>to concrete measures we have implemented<br />

<strong>in</strong> the <strong>IMS</strong> Group, we launched the project<br />

<strong>IMS</strong>ocial <strong>in</strong> close adherence to the pr<strong>in</strong>ciples of Corporate<br />

Social Responsibility (CSR).<br />

But for us at <strong>IMS</strong>, <strong>IMS</strong>ocial is more than just a project!<br />

<strong>IMS</strong>ocial is a belief and stands for the values of our corporate<br />

philosophy.<br />

After all, the sooner even m<strong>in</strong>or defects – which <strong>in</strong> steel<br />

products can already render them useless – are detected,<br />

the faster mach<strong>in</strong><strong>in</strong>g processes can be corrected.<br />

And precisely this contributes significantly to active climate<br />

protection as it is no longer necessary to produce<br />

new products to substitute defective ones, thereby<br />

sav<strong>in</strong>g energy and water, and also reduc<strong>in</strong>g reject rates<br />

significantly.<br />

We not only want to achieve susta<strong>in</strong>ability <strong>in</strong> our products<br />

and customer relations, but also place the same<br />

demands on our social, ecological and economic responsibility.<br />

The first thought that comes to m<strong>in</strong>d <strong>in</strong> connection with<br />

the non-contact measur<strong>in</strong>g systems from <strong>IMS</strong> for the<br />

steel, non-ferrous metal and alum<strong>in</strong>ium <strong>in</strong>dustries is<br />

certa<strong>in</strong>ly not one of active conservation of resources.<br />

However, our isotope, x-ray and optical measur<strong>in</strong>g systems<br />

do exactly that: they save and preserve resources!<br />

The <strong>IMS</strong> product portfolio comprises numerous measur<strong>in</strong>g<br />

systems and processes for various types of measurement.<br />

Our systems deliver and document exceptionally<br />

precise measurement results under the toughest<br />

conditions <strong>in</strong> hot and cold roll<strong>in</strong>g mills as well as service<br />

centres. In this way it is possible to detect material defects,<br />

surface irregularities, tolerance and dimensional<br />

deviations and many other factors that, <strong>in</strong> the worst<br />

case, would lead later to material rejects at an early stage<br />

dur<strong>in</strong>g the manufactur<strong>in</strong>g process.<br />
