For the steel industry, the development of materials will gain in importance in the future. With the complexity of material properties growing fast, it is essential to develop process technologies that ensure the production of these new materials with high productivity and constant quality. While on the one hand the process models and plant technology available today must keep pace with this development, the new underlying conditions such as the saving of resources, CO₂ emissions and energy consumption must be fulfilled on the other hand. To implement the above, plant designers and builders must come up with suitable technical solutions.
