Materials and Process Development – Hot and Cold Strip

The core activity of the department is the development of new materials for hot-rolled and/or cold-rolled strip with an application-oriented design. The technologies required are specified precisely on the basis of existing plant configurations and developed further, if necessary.

The manufacture and processing of new materials may require moving away from conventional process chains towards an innovative process technology that has been fundamentally revised. For example, the strip casting method developed in accordance with the DSC process and in collaboration with competent partners enables high manganese-alloy lightweight steels offering both high strength and ductility.

Other examples of innovative projects handled by the department include the following:

  • Isotropic higher-strength steels up to tensile strength class 340 with Pretex structure in cold-rolled and
  • hot-dip galvanized form Hot-rolled and hot-dip galvanized multi-phase steels
  • Steels to meet special enameling requirements
  • Hot strip that is resistant to acid gas for spiral-welded pipes
  • Water-quenched and tempered hot and cold-rolled strip grades, as well as air hardening steels

In order to support the core tasks, the department also works on the theoretical and experimental simulation of material properties during production. The aim is to achieve the consistent description and optimization of the material properties, ranging from manufacture and processing to long-term utilization under extreme conditions.

Advanced methods and equipment are utilized in the metal science and metallography laboratory in order to adequately record and assess the microstructural conditions of the steels. New technologies in the fields of structural and materials analysis are developed, specified and perfected to the extent necessary for the assessment of microstructural reactions in new materials.

The development work focusing on online testing and sensor technology concentrates on recording material data and properties. The relevant methods are developed or modified to meet the special thermal and dynamic conditions of the respective production mill. They are employed in quality control in production as well as in the development of new steels.
