An affinity for Dillinger iron and steel. In 1685, Louis XIV gave his “Oui” to iron production at Dillingen, whereas

Kaiser Wilhelm II had the steel plates for his navy made here. Now, at the dawn of the 21st century, Dillinger

Hütte is a modern industrial group that leads the world in the production of heavy plate. Nonetheless, traditional

values such as reliability and trust still have the very highest priority for us. We apply technical perfection,

love for detail and enormous enthusiasm to even the very largest challenges. The following tour of our plant

shows you how.

Prospects for the future:

The success story continues.


WHERE IS THE OUTLOOK GOOD

EVEN WITHOUT WINDOWS OR PLATFORMS?

In our plant. The outlook for obtaining optimal, tailor-made steels is great, thanks to our highly professional

steelmakers and ultra-modern technology. At Dillingen, the customer, blast-furnace operator, steelworker,

rolling-mill operator and sales manager are brought together around one table. Orders are painstakingly

discussed down to the last detail. If new and innovative solutions are needed, we find them through cooperation

with our researchers and experts from the various plants. Each can depend 100% on the other – that’s the

only way to achieve the quality that makes us world famous.

Heavy plate – for us, this product signifies a broad range of dimensions and a minimum of 2,000

grades of steel. We develop steels with the most diverse ranges of properties to ensure their precise

suitability for use in bridges, high rise buildings, offshore platforms and drilling rigs, ship building,

large-diameter line pipes, boilers, pressure vessels, construction machinery, heavy-duty machines,

wind farms and much more, too. A steel may only include the “Di” prefix in its name once it has

attained the status of a trademark Dillingen product. Our Dillidur and Dillimax trademark steels

have become world famous. And many of our other steels, such as Dicrest, Dimo and Dipro, have

also made names for themselves – names that experts rely on around the world.

Europe’s tallest office block

(298.74 m) can be found

in Frankfurt am Main.

Star architect Sir Norman

Foster’s masterpiece is a

daring blend of concrete,

glass and Dillingen steel:

DI-MC.


WHERE CAN YOU FIND THE “DEAD MAN”?

In the center of the blast furnace (it’s a pyramid of coke that acts as a distributor of gas). The blast furnaces in

our hot-metal plant are state-of-the-art. Their massive outlines may be reminiscent of a past century, but in

reality they are ultra-modern production facilities. High-tech systems monitor and control the processes in

their hot core and its surroundings. In addition, the composition and properties of the burden (the material

fed into the blast furnace) are submitted to continuous, ultra-strict checks – a vital step in achieving the topquality

steel that we pro -duce.

8


Environmental protection is an especially important factor in in dustrial

production. Our company‘s environmental standards define environmental

protection as an integral component of corporate po licy.

Provisions include, for example, closed cooling-water circuits and the

almost complete forwarding of by-products and residues to other industries

(for instance, energy and construction) for environmentally safe

use, or for recycling back into our own production cycles. Steel itself is

a natural material and is 100 % recyclable.

The imposing Erasmus Bridge in Rotterdam is actually two

bridges in one: a 410 m long cable-stayed suspension bridge

and an 89 m-long flap bridge, the latter widely considered

to be a masterpiece of flap-bridge engineering. And it’s all

made possible by an ultra-modern structural steel: DI-MC.


WHICH WASHING CYCLE OPERATES

AT 2000 °C?

The oxygen top-blowing process in our steelworks. This is where undesirable „tramp“ elements originating

from the ore are eliminated and the liquid iron (re ferred to as “hot metal”) is converted to crude steel. Correct

and precise alloying of raw steel is a precon dition for attaining steel‘s optimal properties. Ultramodern technology

enables us to adjust the very smallest alloying-element contents to a precision of four decimal places –

which in practice means the achievement of a boron or titanium content accuracy of just 2 kg in 185 tonnes

of melted steel. Oxygen treatment in the converter (“refining”), and secondary metallurgical ladle treatments

in our vacuum facilities, assures attainment of ultra-clean steels.

10


Every year, we invest around 50 million Euro in the latest technology

and research, to keep us constantly at the leading technological

edge, and to enable us to improve and expand quality and

product specifications. Our plant and equipment are serviced

and maintained by the people who work on them, assisted by

our dedicated, highly specialized maintenance departments. The

benefits: avoiding disruptive problems and assuring uninterrupted

production.

11

In the Gulf of Mexico,

in waters 535 m deep,

one of the highest offshore

structures ever

built defies the forces

of nature: the Petronius

Tower. To keep it stable,

the 564 m-high tower

has to be able to move

with the motion of the

wind and waves.


WHICH TOP PERFORMER

IS AT ITS BEST AT THE BOTTOM?

Our vertical continuous caster. This machine enables us to produce clean, porosity-free, homogeneous steels

throughout a slab thickness range up to 400 mm. The secret: so-called “soft reduction” – the strand shell is

compressed during casting in such a way that a material cross-section with absolutely homogeneous properties

is achieved through to the center of the slab. For extra thick and heavy plates, we use the traditional ingotcasting

method, with ingots of a maximum weight of up to 63 tonnes, and a thickness of up to one meter.

12


Our research activities are the source of our new products and production

refinements. Internal departments and a range of laboratories

work continuously to optimize production techniques and develop new

heavy- plate production methods and technologies. And our scientists

don‘t need to travel much, either. Their experiments and tests are performed

near our production plant, with the extra benefit that the results

can quickly be translated into new and improved production practice.

How big must an earthmover

be to earn the name

“the world’s largest hydraulic

excavator”? Answer: 24.9 m

high and 8.6 m wide, and

equipped with a bucket

whose capacity of 42 m3 is

sufficient to accommodate

a whole class of school

children. DILLIMAX.


WHO RUNS THE WORLD‘S

MOST POWERFUL MOTORS?

The Dillingen rolling mill, with its superlative spe cial equipment. Electric motors with torque ratings of 4950

kilonewton meters each (equal to the power of around 20,000 cars) drive the 5.5 m four-high mill, the most

powerful rolling stand anywhere in the world. Thick slabs can be rolled with constant precision to any plate

or strip thickness required, with a rolling force of up to 108 meganewtons. Thermomechanical rolling is a

Dillingen specialty. This process imparts not only the geometry of our heavy plate, but also its mechanical

properties, such as strength, toughness and hardness.

14


What service means to us: intensive customer liaison and mutually trusting and

cooperative partnership, combined with a broad range of semi-finishing procedures.

We have multiple advisory teams specializing in the diverse requirements of our various

groups of customers. Our exceptionally broad range of formats and enormous

selection of grades are the basis for our individual service packages. In many cases, we

are awarded highly complex orders simply because we are the only supplier with the

necessary capabilities – an enormous compliment to our skills.

15

At sea, too, Dillingen plate is superlative: The giant ocean liner Queen

Mary II is the world’s largest passenger ship, with a length of 345 m, a

height of 72 m, and a beam of 41 m. The ship provides 2,620 guests with

numerous and diverse opportunities for on-board recreation. DIMARINE.


DOES THE PLANT HAVE A HALL

OF MIRRORS?

Naturally. The mirrored room at Dillinger Hütte takes the form of the cooling and inspection beds. After surface

inspection, ultrasonic methods tell us the quality of the center of our heavy plate. Chemical and mechanical

procedures are used to register other important quality-relevant criteria. Continuous in ter nal production monitoring

thus ensures the constant high quality of our plate products. An all-encom passing and certified quality

management system and a proactive Total Quality Management culture are part of our everyday working life.

All this enables us to supply our customers with precisely the steel they ordered, every time – as we document

in detail on the material test certificate!

16


Every order is an obligation to perform. At Dillinger Hütte, however, we always want to do more

than “just” supply the product. The solution: cooperative partnership with our customers. An

important channel for this is frank and open communication, via our www.heavyplate.com

communication and service platform on the Internet, for example. Here, our customers can obtain

information about their orders at any time, and request deliveries. But despite all the modern

media now available, we never forget the importance of personal contact with customers – we

know that customer relations grow on a person-to-person foundation. And that’s what we find

so exciting.

What eats its way through the earth,

played a decisive role in the construction

of the fourth bore of Hamburg’s

Elbtunnel, and has a cutting shield

with a diameter of 14.2 m? Right –

“Trude”, the world‘s largest tunnel

boring machine.


WHAT CRUISE ON THE SAAR

OFFERS THE BEST VIEWS?

The scheduled and charter trips from the Saar louis/Dillingen harbor on the Saar. Apart from the crews, however,

only raw materials on their way to the plant and finished products for delivery around the world can enjoy

the marvelous scenery on the banks of the Saar. Alongside Europe‘s rail infrastructure, the harbor is our direct

link to the North Sea ports. With technical facilities that make it one of Europe’s most modern, Saarlouis/Dillingen

harbor handles some three million tonnes of freight each year. A special logistics department ensures

trouble-free shipment by water, rail and road, and is responsible for trans mission of the associated shipping

and loading data – yet another sector in which top performance is an everyday fact of life.

18


As a well-established and globally active producer of heavy plate,

Dillinger Hütte has its own, tightly organized Sales & Marketing team.

Local sales staffers are in daily contact with their customers. Their colleagues

in the central Sales and Marketing departments support them.

Existing and potential customers value their dependable ex perience and

know-how.

19

Despite their deserved fame for flatness, Dillingen plates handle

curves just as capably. In gigantic cylindrical storage tanks for high-

pressure liquefied gas, for example. This facility, at Leuna, Germany,

is one of Europe’s largest, with a capacity of 22,500 m3. DICREST.


WHERE IS IT NOT LONELY AT THE TOP?

In our group. With its subsidiaries, Dillinger Hütte is Europe‘s largest manufacturer of heavy plate. We produce

and sell around 2 million tonnes of plate each year. In addition to our Dillingen headquarters – also the lo cation

of the Zentralkokerei Saar and Roheisengesellschaft Saar production facilities – and the GTS Industries rollingmill

at Dunkirk, France, the group also includes a whole series of primarily European enterprises furnishing the

most diverse range of services for heavy plate. These include stockists and flame-cutting establishments, as

well as large-caliber line pipe manufacturers, sales com panies and freight organizations. This is our concept of

the integrated supply chain – from the ore up to the fully finished product.

20


Dillinger Hütte, in partnership with other group companies, can provide numerous services

and processes for finished plate. The spectrum ranges from edge-machined plates via

precise, to-the-millimeter flame-cut components, dished trays and vessel ends in all wall

thicknesses, spherical segments, up to and including pressings and longitudinally welded

vessel-shell components. We can also perform trial assembly – we have the necessary faci lities,

staff and know-how. In short, we can do everything that our customers either can’t or don‘t

want to do themselves – it’s that simple!

21

DILLINGER HÜTTE GTS, the major

European heavy plates producer,

intends to achieve highest performances

in steel together with

its customers and associates.


COULD THERE BE A MORE ELOQUENT

COMMITMENT TO ACHIEVEMENT?

Hardly. Top performance results from optimum interaction between people and technology. Fascina ting hightech

plants are only the foundation. Down the generations, the basis for success has been the teams that

master plant operation, provide customers with highly competent advice, and complete orders to our customers’

total satisfaction. People who accept the competitive challenge – in sport and at work, as a team – and

give their best, together, every day. With the will to innovate, with enthusiasm, and with commitment and

pleasure in achievement.
