thyssenkrupp Steel announced the successful start of trial operation and casting at its new continuous casting line 4 (SGA 4) in Duisburg, marking its largest single investment in recent decades. 

The modern line is equipped with high-tech automation and casting technology, delivering slabs with improved shape accuracy and surface quality. The SGA 4 is a key part of the company’s strategy to enhance efficient and sustainable steel production. Full operations will be phased in over the coming weeks, supported by a new fully automated slab storage yard and a modernized hot strip mill 4 with a new preliminary line and two new walking beam furnaces. 

The new system replaces older equipment and aims to produce high-strength, dimensionally accurate steels for sectors like electric mobility, lightweight construction, as well as the energy sector.
