RECENT PROJECTS<br />
Gerdau Sayreville NJ awarded Russula contract for<br />
Last December, Gerdau awarded<br />
Russula the contract to supply the<br />
Contact Cooling Water Treatment<br />
Plant for their 800,000 tpy capacity<br />
rebar mill, in Sayreville, NJ, USA.<br />
The rolling mill currently produces<br />
rebar at average/maximum rates of<br />
78/150 short tons/h (71/136 metric<br />
tons/h) rolling <strong>11</strong>5mm square billets.<br />
The mill scale generated by the<br />
rolling process at these production<br />
rates are 1,376/2,645 Lb/h<br />
(624/1,200 kg/h), with a mill scale<br />
density of 325 Lb/ft 3 (5,200 kg/m 3 ).<br />
The project will be implemented in<br />
two phases. In the first phase, the<br />
new water plant will treat a total<br />
flow of 4000 GPM from the rolling<br />
mill and reheat furnace, and the second<br />
phase will include the quenching<br />
system, which requires an<br />
additional water flow of 3500 GPM.<br />
For the 4000 GPM treatment, the<br />
plant design will follow the Russula<br />
"Four Stage Process" for contact<br />
water circuits. Water from the<br />
rolling mill will be treated first in<br />
the scale pit to remove coarse particles<br />
that have a size greater than or<br />
equal to 200 microns. The density<br />
difference between the water and<br />
the scale, causes the larger, heavier<br />
scale particles to be deposited on<br />
the bottom of the pit, and subsequently<br />
extracted by a clamshell<br />
bucket.<br />
After passing through the scale pit,<br />
the water will continue to the decanting<br />
process, where by longitudinal<br />
drag small scale particles, oils<br />
and grease are removed. Coarse<br />
particles that gather at the bottom of<br />
The 4000 GPM contact<br />
cooling water will go<br />
through a four stage treatment<br />
process consisting of<br />
a scale pit, decanting<br />
process, ring filtration and<br />
cooling towers. The water<br />
treatment plant flow diagram<br />
is illustrated on the<br />

the decanters will be pumped to the<br />
sludge area and oil floating on the<br />
surface will be taken off by the top<br />
of the bridge scraper and removed<br />
by the oil skimmer. The decanted<br />
water will then pass to the ring filtration<br />

RECENT PROJECTS<br />
Three consecutive projects at Gerdau Cartersville<br />
Following the recent modernization of the DC drives<br />
of the bar mill, Russula has won a contract for the 4<br />
strand continuous caster and complete bar mill control<br />
revamp at Gerdau Cartersville in GA, USA.<br />
The projects will be implemented in two phases during<br />
planned shutdowns. In the first phase, one strand of the<br />
continuous caster and the bar mill will be<br />
commissioned in September 2015. The second phase<br />
consists of the revamping of the other three continuous<br />
caster strands, scheduled for December 2015.<br />
A multi-phase revamp approach allows mills to upgrade<br />
obsolete control equipment and minimize mill<br />
downtime, which reduces the impact on production.<br />
Rolling mill drive upgrade completed in just six days<br />
The first project, implemented in December 2014, consisted<br />
of upgrading the main DC drives of the bar mill<br />
from ABB DCS600 to DCS800. The entire mill downtime<br />
for the uprade was only six days. Even though the<br />
upgrade was from the same drive family, due to the<br />
various sizes and configurations, it was necessary to<br />
propose solutions for each case, seeking the best technological<br />
improvement while minimizing the investment.<br />
The proposed solution is based on using DCR upgrade<br />
kits, which replace all electronic drive control while<br />
keeping intact the power stacks. The kits are highly<br />
modular, allowing the upgrade to be accomplished<br />
quickly. The main benefits were:<br />
- Gerdau Cartersville mill obtained the high<br />
performance offered by ABB DCS800 drives<br />
without having to change the power stacks, thus<br />
optimizing the economic investment.<br />
- Replaced obsolete equipment and software, which<br />
was expensive to maintain due to the high price of<br />
spare parts replacement for discontinued<br />
equipment.<br />
- Established a standard and transparent<br />
communication path between the PLCs and<br />
standard drives, expanding the communication<br />
capabilities of these systems with other external<br />
control systems.<br />
Control system upgrade for bar mill and continuous<br />
caster scheduled for September 2015<br />
This second project is currently under development<br />
and consists of the upgrade of the existing control<br />
system and HMI architecture for the bar mill. The<br />
current ABB AC450 PLCs with the ABB AS500 SCADA<br />
operator inferface will be replaced with the ABB<br />
AC800M series and Wonderware Intouch. Russula mill<br />
control will be implemented for the entire line from the<br />
first stand to the cooling bed.<br />
New DC drives supplied by Russula for the sideguards and<br />
screwdown of the DUO two high stand revamped in 20<strong>11</strong><br />

RECENT PROJECTS<br />
Once again, ArcelorMittal Acindar chooses Russula for<br />
their new 450,000 tpy bar mill in Argentina<br />
Russula supplied the electrical equipment and installation for ArcelorMittal Acindar´s bar and wire rod mill in 2007<br />
In 2007, Russula supplied the electrical equipment and<br />
installation for Acindar´s new 500,000 tpy bar and wire<br />
rod mill. <strong>No</strong>w, eight years later, Russula is proud to receive<br />
an order for the complete control system software<br />
for Acindar´s new 450,000 tpy bar mill.<br />
The new mill is currently under construction on the site<br />
of the Old Mill 1, in Villa Contitución, Santa Fe, Argentina.<br />
Commissioning is planned for 2015.<br />
The heart of the order is to engineer and implement<br />
Russula Mill Control in the new bar mill. Part of the<br />
original electrical equipment from Old Mill 1 will be<br />
reused. Two PLC´s will be reutilized for the reheating<br />
furnace and 4 PLCs for the continuous mill. Existing remote<br />
IO´s, local panels, power supply and communications<br />
will be reused.<br />
Russula will supply a new PLC, IO hardware and<br />
MCCs for the water treatment plant control. In addition,<br />
Russula will supply MCCs for the reheat furnace,<br />
a new main operator control desk for the mill, servers,<br />
installation supervision, commissioning support and<br />
training necessary to ensure an efficient start-up and a<br />
productive rolling mill.<br />
- High speed flying shears and rotating channels<br />
for lines A & B<br />
- Water treatment plant<br />
- Cooling bed and cold shear<br />
- Bundling area<br />
- Fluid systems<br />

RECENT PROJECTS<br />
Successful startup of Gerdau Corsa´s section mill drive<br />
and controls upgrade<br />
Russula upgraded the automation system and drives<br />
for Gerdau Corsa´s section mill. The mill was successfully<br />
started up at the end of October, early <strong>No</strong>vember<br />
2014. Gerdua Corsa´s 150,000 tpy section mill is located<br />
in Tlalnepantla, Mexico.<br />
As an independent provider, Russula has the flexibility<br />
to integrate the ideal combination of hardware and software,<br />
mutually agreed upon with the customer for their<br />
particular mill. For this project, Russula integrated the<br />
control system and drive hardware from four different<br />
suppliers.<br />
The Russula Automation and Service solution for this<br />
mill includes:<br />
- Siemens S7-400 PLCs<br />
- DC Drive Rebuilds - ABB DCS800<br />
- New DC drives - ABB DCS800<br />
- New AC Drives - ABB ACS800<br />
- HMI - Wonderware<br />
- Electrical, Software and HMI Engineering<br />
- Main operator control station<br />
- 3 Simotion controllers for the shears<br />
- Iba high speed data acquisition system<br />
Russula was responsible for the installation supervision,<br />
commissioning, operator/maintenance training<br />
and three months of production assistance.<br />
The Russula Mill Control Scope:<br />
- Rolling mill configuration and mill tuning<br />
- Cascade mill control<br />
- Inter-Stand manual control<br />
- Mill speed references and management of start<br />
and stop of each section<br />
- Tension control<br />
- Tracking and cobble detection<br />
- Shear cut control<br />
- Rest cut removal<br />
- Cooling bed entry and exit sequencing<br />
- Phantom billet<br />
- Alarm and Interlocking<br />
Even after many years of operation, DC motors<br />
are often in an excellent shape. Since the technology for<br />
power stacks and power circuits does not change<br />
rapidly, upgrading the drive electronics will often give<br />
the same result as replacing the entire drive. This is an<br />
attractive upgrade path for mills as the installation is<br />
quicker and the equipment less expensive than buying<br />
complete new drives.<br />
This is the fourth project Russula has implemented for<br />
Gerdau Corsa in Mexico in the past two years. With the<br />
successful startup of the section mill, Russula strengthens<br />
its relationship with Gerdau Corsa.<br />

Excellent results after drive and control revamp at<br />
Gerdau Sidenor Reinosa<br />
In August 2014, Russula successfully started-up the<br />
Gerdau Sidenor Reinosa DUO blooming mill after implementing<br />
a drives and control upgrade. Russula was<br />
also responsible for the engineering, installation supervision<br />
and commissioning.<br />
The Russula automation and control scope includes:<br />
- Blooming control for 6 and 8 ton blooms<br />
- Stand 2 and 3 control<br />
- Tilting device control 1 and 2<br />
- Sideguides 1, 2, 3 and 4 control<br />
- Upper cylinder control stand 1<br />
- Engineering<br />
- Installation support<br />
- Commissioning<br />
The Russula Control System was constructed using a<br />
selection of hardware chosen specifically for this project,<br />
including a Siemens PLC 414-3DP, new Sinamics<br />
DCM 220V (3 phase) drives, 5 remote I/Os and WinCC<br />
HMI. All drives were delivered already mounted on<br />
panels and then installed in the existing electrical cabinets.<br />
The communication between the drives, operator desks<br />
PLC and remote IOs was with profibus, while ethernet<br />
was used to communicate the new HMI to the PLC.<br />
As part of the software development, a new recipe system<br />
was put into operation. The operators found the<br />
recipes easy to modify and store for fast changes of<br />
product dimensions, grades and shapes. Without<br />
doubt, the revamp improved the overall productivity<br />
and product quality of the DUO blooming mill.<br />
Located in the municipality of Cantabria, Spain, the<br />
Gerdau plant is dedicated to fabricating specialty steels<br />
as well as forging and casting large turbine shafts for<br />
shipbuilding.<br />

10mm bars, using the 4 slitting scheme.<br />
The rolling mill is fed by a 90 tph walking hearth reheating<br />
furnace. The plant layout includes a 20-stand<br />
continuous mill with two outlets, one for straight bar<br />
and the other for wire rod in coil. The rod outlet includes<br />
a one 10-stand, high-speed twist free finishing<br />
block fed from the bar mill finishing stands. The smaller<br />
bar sizes are produced on four strands, to take advantage<br />
of the mill´s capacity for the entire product range.<br />

CUSTOMER SERVICE<br />
Russula builds technical service team in the US dedicated<br />
to mill production assistance<br />
Russula has built a technical team<br />
with a 100% focus on delivering operational<br />
support and improvements<br />
to long product rolling mills.<br />
Based in Sturbridge, MA, USA, this<br />
multi-disciplinary service team consists<br />
of operations, mechanical and<br />
electrical experts.<br />
Different from other suppliers,<br />
which fold customer service into the<br />
area of revamping existing plant<br />
equipment, this team is solely dedicated<br />
to making mills run better.<br />
”At times, equipment suppliers<br />
base their standardized solutions on<br />
offering equipment, equipment and<br />
more equipment. Here at Russula<br />
we are interested in solving the<br />
problems at our customer´s mills so<br />
they run more efficiently.” says<br />
Keith Fiorucci, Head of Research<br />
and Development for Russula.<br />
Standardized solutions become a<br />
one-size-fits-all compromise that affects<br />
many steel mills. However not<br />
all steel plants have the same operational<br />
difficulties. Custom solutions<br />
require a holistic knowledge<br />
of the long product rolling process.<br />
It is not enough to understand just<br />
how the electrical configuration<br />
affects production, but how the<br />
process impacts everything.<br />
”When a rolling mill asks me to<br />
visit, 85% of the time is spent diagnosing<br />
the short-comings in the<br />
mill. The other 15% is proposing the<br />
best way to fix them. Depending on<br />
the root cause of these reoccurring<br />
issues, revamping equipment may<br />
or may not be necessary. Many<br />
times the problems can be fixed<br />
without huge CAPEX investments.”<br />
adds Keith Fiorucci.<br />
This mill production assistance<br />
team will also assist in Russula´s ongoing<br />
Greenfield and revamp projects<br />
during hot commissioning.<br />
Their operational input will help expedite<br />
start-ups and ensure the mill<br />
returns to sustained production.<br />
The primary scope of work includes:<br />
• Roll Pass Design and<br />
Consulting<br />
• Process Optimization<br />
• Modern Methods of<br />
Process Analysis<br />
• Custom Equipment Design –<br />
small/medium scale projects<br />
• Small and Medium sized<br />
upgrades<br />
• Customized Solutions<br />
• Internal Training<br />
• Operational Training<br />
- Process Reviews – On Site<br />
- Hands on Courses<br />
Mill floor, directly with<br />
operators<br />
- Production Assistance<br />
- Troubleshooting<br />
Customer satisfaction requires having<br />
continual close customer contact.<br />
These teams will purposefully<br />
be kept small to give a more personalized<br />
service that engages the<br />
customer. ”Throwing more people<br />
at a problem does not make the solution<br />
better. You need to gather the<br />
right mix of people depending on<br />
the issue at hand.” commented<br />
Keith Fiorucci. The technical service<br />
team will provide production assistance<br />
for steel mills globally.<br />

Successful EAF upgrade at Votorantim Siderúrgia in<br />
Barra Mansa, Brazil<br />
Russula simplified the<br />
control configuration to<br />
one platform during the<br />
EAF <strong>No</strong>. 1 upgrade at<br />
Votorantim Siderúrgia.<br />
The EAF was successfully<br />
commissioned in January<br />
of this year.<br />
Votorantim Siderurgia contracted<br />
Russula to upgrade the existing<br />
electric arc furnace <strong>No</strong>. 1. at its Barra<br />
Mansa plant located in Rio de<br />
Janeiro, Brazil. In early January of<br />
this year, the control system modernization<br />
was successfully completed.<br />
The EAF has a capacity of 51<br />
ton/tap-to-tap cycle.<br />
In this project, the existing control<br />
configuration, previously provided<br />
by multiple equipment suppliers,<br />
was replaced with one single platform.<br />
This simplified maintenance<br />
and spare parts inventory. In particular,<br />
the old MCC panel, Siemens<br />
Step 5, Rockwell SLC 500 PLCs<br />
were replaced with a new MCC<br />
panel and a new Siemens Step 7<br />
PLC. The Step 7 PLC is widely used<br />
in the steel sector, to ensure spare<br />
parts availability and minimize<br />
electrical failure downtime.<br />
EAF <strong>No</strong>. 1 Control Scope<br />
The control funcionality of the EAF<br />
<strong>No</strong>. 1 included:<br />
- Energizing electrodes<br />
- Steel melting process initiation<br />
- Electrode and furnace<br />
movement to the liquid steel<br />
casting operation<br />
- Interface with the electrode<br />
regulation system<br />
- EBT ladle car and retractable<br />
platform movement<br />
- Furnace tilting platform and<br />
roof removal mechanism<br />
The existing MCC panel, containing<br />
logic performed by contactors and<br />
relays, was responsible for the control<br />
of the medium voltage unit, the<br />
hydraulic unit, the electrode regulation<br />
system and the furnace movement<br />
system. The medium voltage<br />
unit consisted of a motorized drive<br />
disconnect and a main circuit<br />
breaker to energize the electrodes<br />
and start the steel melting process.<br />
The hydraulic unit controlled the<br />
electrode movements and furnace<br />
movement to the liquid steel casting<br />
operation. For the electrode regulation<br />
system, the MCC interfaced<br />
with an auxiliary PLC AMI-GE, responsible<br />
for the regulation. Lastly<br />
the furnace movements system consisted<br />
of the logic of locking movements,<br />
gate valve, furnace tilting,<br />
roof lifting, roof removal mechanism<br />
and opening of the slag door.<br />
The existing PLC Siemens Step 5<br />
contained the logic responsible for<br />
the control and drive of the ladle car<br />
EBT and retractable platform. The<br />
PLC interfaced with an auxiliary<br />
controller Tiefenbach, which was<br />
responsible for triggering the<br />
proportional valve for the furnace<br />

The giant of Bethlehem roars again in Monclova, Mexico<br />
By Pablo Orvañanos<br />
April 12, 1936<br />
Bethlehem Steel Company, Sparrows Point<br />
(A. Aubrey Bodine/Baltimore Sun)<br />
October 8, 1939<br />
Bethlehem Steel Company, Sparrows Point<br />
(A. Aubrey Bodine/Baltimore Sun)<br />
October 10, 1951<br />
A worker in the blast furnace at Bethlehem Steel<br />
Co. In the 1950s, the Sparrows Point plant in Baltimore<br />
County was the world's largest steel mill.<br />
(Robert F. Kniesche/Baltimore Sun)<br />
The story starts in 1889, when<br />
steel was first produced by the<br />
Pennsylvania Steel Company at<br />
Sparrow's Point. By the mid-20th<br />
century, the Sparrow's Point<br />
plant was the world's largest<br />
steel mill, stretching 4 miles (6.4<br />
km) from end to end and employing<br />
tens of thousands of<br />
workers. Bethlehem Steel purchased<br />
the mill in 1916 and due<br />
to a superb reputation, its steel<br />
ended up as girders in the<br />
Golden Gate Bridge, as cables<br />
for the George Washington<br />
Bridge, and were a vital part of<br />
war production during World<br />
War I and World War II.<br />
The business was so profitable<br />
that Bethlehem Steel Corporation<br />
acquired the Sparrow's<br />
Point shipyard in 1917. The<br />
Shipyard was one of the most active<br />
shipbuilders in the United<br />
States, delivering <strong>11</strong>6 ships in<br />
the 7-year period between 1939<br />
and 1946.<br />
Changes in the steel industry,<br />
including a rise in imports and a<br />
move toward the use of simpler<br />
oxygen furnaces and the recycling<br />
of scrap, led to a decline in<br />
the use of the Sparrow's Point<br />
complex during the 1970s and<br />
1980s.<br />
To combat the crisis, in August<br />
of 1991 Bethlehem Steel Corporation<br />
invested more than $200<br />
million dollars to modernize the<br />
Sparrows Point 68-in hot strip<br />
mill. The modernization included<br />
two new 300 ton/hr<br />
walking beam furnaces, a combination<br />
of new and refurbished<br />
roller tables, and a 4-h reversing<br />
roughing mill with attached<br />
entry side edger.<br />
Unfortunately, the big investment<br />
couldn’t stop the downward<br />
spiral of events that caused<br />
Bethlehem Steel Group to go<br />
bankrupt in 2001. Since then, the<br />
Sparrows Point plant has passed<br />
through the hands of four different<br />
owners, including Mittal &<br />
Severstal, who couldn’t do anything<br />
to save the once biggest facility<br />
in the USA. The definite<br />
end to the Sparrows Point plant<br />
came in January 2013, when all<br />
the equipment of the facility was<br />
auctioned to different bidders all<br />
around the world.<br />
Fortunately the 68-inch hot strip<br />
mill quickly found a new home<br />
on the other side of the border,<br />
in the steel city of México, Monclova,<br />
where Altos Hornos de<br />
México (AHMSA) is collaborating<br />
with the best local and foreign<br />
engineers to make the giant<br />
roar again. AHMSA plans to utilize<br />
the 68 inch hot strip mill to<br />
replace their current mill, increasing<br />
their production capacity<br />
by 10%. The actual capacity<br />
of the hot strip mill is 2.8 million<br />
ton/year.<br />
The project is currently underway,<br />
as the foundations are<br />
being prepared to receive the<br />
new mill without stopping production<br />
in the current mill.<br />
AHMSA has contracted Russula<br />
to provide engineering services<br />
for the first stage of this complex<br />
equipment transfer project.<br />
23 Russula Newsletter <strong>No</strong>. <strong>11</strong> April 2015 - Copyright © by <strong>RUSSULA</strong> S.A.
RECENT PROJECTS<br />
AHMSA contracts Russula for the design and supply of a<br />
new roller table for the hot strip mill<br />
The new roller table, designed and manufactured by Russula ensures that AHMSA will have a smooth production<br />
during the 2.4 million tons/year hot strip mill installation<br />
The final site of the new mill will be<br />
a couple of meters upstream f r o m<br />
the current mill. Russula was responsible<br />
for the design, supervision<br />
and construction of the new<br />
foundations to support the new<br />
mill.<br />
Since most of the work will be done<br />
with the current mill in operation,<br />
safety is one of Russula’s main concerns.<br />
Therefore Russula has designed,<br />
manufactured and installed<br />
a new support for the roller table<br />
through which production will pass<br />
during the excavation and<br />
construction of the foundations.<br />
To ensure the building can support<br />
the weight of the new hot strip mill<br />
during the equipment transfer operation,<br />
Russula conducted a feasibility<br />
study of the structure to<br />
determine the required modifications<br />
and developed the reinforcement<br />
engineering.<br />
In a couple of months everything<br />
will be ready in Monclova to receive<br />
the mill, and the giant will write<br />
another chapter of his own story.<br />
The large 4-h reversing mill, with <strong>11</strong>30<br />
sq in mill posts, utilizes 47 in diameter<br />
work rolls and 60 in diameter backup<br />
rolls. Main drive power is obtained from<br />
two 6000 HP double armature motors<br />
driving through 30 ft long universal<br />
spade and slipper spindles. An entry-side<br />
heavy duty vertical edger is attached to<br />
the main mill housing. The two 43.5 in<br />
caliber type work rolls, sized for 3 in./<br />
pass edging on 10 in slabs are driven by<br />
two vertical mounted 2.000 HP motors<br />
through large universal spindles.<br />

RESEARCH, DEVELOPMENT & INNOVATION<br />
Five Spanish Universities join forces in Industrial<br />
Mathematics Program to solve various industry problems<br />
During the last fifteen years, Russula has collaborated<br />
with many universities to develop innovative technological<br />
solutions that generate knowledge and value to<br />
the products offered to our customers. With this idea<br />
in mind, Russula´s R& D department, participates another<br />
year in the Masters in Industrial Mathematics during<br />
2015.<br />
This master is formed by members of academic committees<br />
from 5 different universities in Spain. Three are<br />
located in the the Galician region, Santiago de Compostela,<br />
A Coruña and Vigo; and two in Madrid, specifically<br />
Carlos III and Polytechnic University.<br />
The goal of the M2i program is for participating engineers<br />
to face real problems in the industry and develop<br />
solutions through the use of specific software, theoretical<br />
applied analytics and appropriate design tools.<br />
Companies from the industry collaborate by proposing<br />
a problem and monitoring the progress of the project.<br />
Through this collaboration a two fold objective is<br />
achieved: first the engineer is exposed to similar problems<br />
that they may encounter in their professional future<br />
outside their academic envirnoment; secondly, the<br />
companies benefit from receiving a different<br />
perspective to the standard solutions that they are accustomed<br />
to implementing. In addition the participants<br />
in the Masters have at their disposal different analysis<br />
tools and software provided by the Universities.<br />
This is the second year Russula has participated in the<br />
Industrial Problems Workshop for 2015. In 2014, Russula<br />
presented three problems, two of which led to final<br />
projects for the master thesis. The three problems presented<br />
were:<br />
• Project 1 -3D modeling continuous tempering<br />
of steel bars in water boxes.<br />
• Project 2 - Creating a phenomenological model<br />
for convective transport of heat in the combustion<br />
chamber of a steel reheating furnace.<br />
• Project 3 - 3D modeling and simulation of the<br />
flow of escape gas in the billet reheating furnace<br />
combustion chamber.<br />
The results of the three projects were subsequently<br />
used for improvement parameterization in the cooling<br />
process of bars and modeling the behavior of reheating<br />
furnace results.<br />
In 2015, Russula paticipated again in the Industrial<br />

RESEARCH, DEVELOPMENT & INNOVATION<br />
Russula R & D collaborates with Industrial Mathematics<br />
team on three important projects<br />
Project 1 - Percentage of martensite for steel 1020 in a section<br />
with small size corrugation. The blue areas represent a 0% level<br />
of martensite and the red areas show where martensite has<br />
formed.<br />
Project 1 - Real metallographic analysis conducted on the<br />
steel<br />
Project 2 - A velocity map section in its x component for a cross<br />
section of the combustion chamber. This simulation aims to identify<br />
preferred channels with increased exhaust convection heat-<br />
Project 1 - 3D modeling of rebar. Different cross sections<br />
were taken to create the grid, previous to the FEM analysis.<br />
Project 2 - Particle stream lines from a burner in the equalization<br />
zone of a reheating furnace. The model shows the effect of each<br />
burner in the heating of the whole combustion chamber.<br />
Mathematics Workshop, proposing the topic Numerical<br />
simulation of transient flows in a billet reheating furnace chamber.<br />
Numerical modeling of billet reheating in a reheating furnace<br />
clearly depends on an adequate description of convective<br />
flows. Previous numerical simulations (stationary<br />
character) have revealed the presence of complex<br />
structures in the flow of gases from the furnace, which<br />
help to understand the phenomena of heat transfer in<br />
the furnace. Direct modeling of the escape gases by a<br />
predictive tool can be integrated into the plant control<br />
to substantially improve the results in the heat transfer<br />
calculations due to convective effect.<br />
Gas fluxes are strongly non-stationary (even when the<br />
furnace charging is) because of the furnace´s design.<br />
Thus we need to understand how the furnace behavior<br />
affects the dynamic structures of gas flow. Including<br />
this behavior within the logic of mathematical<br />
model logic of the heating furnace (commercially<br />
known as "Level 2C") may improve the calculation of<br />
the bar temperature.<br />
