Salzgitter Flachstahl GmbH has awarded PSI the task of implementing a process control system for the SGA 4 continuous casting plant, which is under construction. The new plant will make it possible to produce especially high-quality steel slabs and provide new capacity for the production of thicker steel slabs. The first cast for the new continuous casting plant is planned for the first quarter of 2010. The process control system will be based on the industry standard PSImetals, which has already been successfully employed by Salzgitter Flachstahl for the SGA 1, 2 and 3 lines. The process control of the continuous casting system forms the link between system control and the steel mill control system, which has also been delivered by PSI. Proven functionalities for the system control, planning data administration, section planning, length optimisation, material tracking and for including process control models will be taken from the existing systems and expanded by new functions for the production of varying thicknesses of slabs.
