DILLINGER HÜTTE GTS - INVESTMENTS IN INNOVATIVE PRODUCTS AND

OUTSTANDING SOLUTIONS IN STEEL

Revision 0, June 2011, 3 pages

More than half a billion euro has been invested in the facilities at the Dillingen site during the

past five years.

A considerable part of the investment volume is aimed at the modernization of the production of

high-quality coke and pig iron as the intermediate for steelmaking. A significant portion of

shares implements the company's corporate aim of sustained - and sustainable - environmental

protection and optimized energy efficiency.

The focus, however, is on further enhancement of the technological leadership enjoyed by

Dillinger Hütte GTS on the world heavy-plate market and on assuring new technological and

highly cost-efficient solutions for customers by means of even higher-quality products with

optimized property profiles.

Significant examples include:

1. Investment in continuous-casting technology:

All components of CC5 have been

completely overhauled and modernized in

a comprehensive revamping project. This

vertical caster's slab format has been

enlarged to a slab thickness of 450 mm -

a world record that yet again underlines

the globally leading role of the Dillinger

steel works in the production of heavy

continuous-cast slabs. By supplementing

the ingot-casting route - which will also

remain in use - the overhauled caster

assists in enhancing the company's

capabilities in the field of thick plates with

high unit-weight.

2. Investments in accelerated cooling facilities:

The existing ACC cooling lines installed at

the GTS plant in Dunkirk and in the rolling

mill in Dillingen have been modernized.

These facilities have been optimized to

ensure that even better combinations of

tensile strength, toughness and workability

can be achieved for the various properties

such as plate types treated on them,

including thermomechanically rolled line

pipe, structural engineering and offshore

grades, and direct-quenched (DQ) structural

types. Expanded potentials in dimensions,

i.e., in thickness and width, are now also

available for these grades.

cast at Dillingen’s CC5.

3. Investment in leveling machines:

Great importance is attached to the flatness

of heavy plates in ensuring their reliable,

highly efficient processing and optimized

service. Dillinger Hütte GTS customers

know that their plates are notable for

particularly good flatness. Our aim is to

supply our products not just in conformity to

the requirements of the relevant standards,

but instead to assure particularly demanding

flatness specifications well above these

requirements throughout the entire format

spectrum. We have invested in new leveling

and plate measurement systems for this

purpose.

Plates up to a width of 5200 mm, a thickness of 300 mm and a length of 19 m can be leveled on

a press specially designed for working of high plate thicknesses and exerting a leveling force of

6500 t. These capabilities make this press the most powerful of its type anywhere in the world.

A new hot plate leveler which, in interaction with the cooling installation, permits achievement of

enhanced flatness specifications for intensively cooled plates, and for thermomechanically

rolled plates (TMCP), in particular, has also been installed in the rolling line of the mill.

4. Investments in finishing equipment:

Extension of cutting capacities, both in

the shearing line and in flame-cutting

installations, makes it possible to cut

the entire format range of heavy plates

to net tolerances with high accuracy.

Particular features of the equipment

installed here include a plasma and

water-jet cutting machine, which

assure optimum cut edge quality and

-tolerances even for sophisticated

special grades.

achievement of ultra-high heavy-plate flatness standards.

quality requirements.

5. Investments in heat-treatment facilities:

Additional facilities for final heat treatment of

plates (normalizing, tempering, annealing

and quenching + tempering), and

developments in the process control of

heat-treatment furnaces, underline our

market leadership in the field of heavy plate

with complex heat-treatment and elevated

quality requirements. Investments in new,

ultra-modern roller hearth furnaces have

therefore been made at both Dillingen and

Dunkirk.

6. Investments in steel application support:

Dillinger Hütte GTS supports its

customers with more than "just" ultramodern

heavy-plate products -

whether it's questions concerning

plate workability, or use for a particular

application, our advisory service

supports clients to use the

technological potentials of our plates

to the limit. Dillinger Hütte GTS is

investing here, too: one good example

is the commissioning in the welding

laboratory of a new "Gleeble"

equipment, a welding-cycle simulator

which provides the user with even

more detailed data concerning his

plates' weldability and welding

characteristics.

All these investments again contribute to achieving our central aim of developing top ultramodern

cost-efficient solutions in steel, jointly with our customers. We may well also have

exactly the special tailor-made solution for your needs - just contact us!
