New casting processes to create innovative steel products: BCT®

In a joint project with Salzgitter Flachstahl GmbH (SZFG and TU Clausthal, we developed a plant casting near-net-shape. Today, Salzgitter uses our innovation to produce high-manganese steel grades.

The BCT® plant was first built on an industrial scale at the SZFG location in Peine. Salzgitter Flachstahl and SMS group commissioning the BCT® plant in December 2012. The process reproducibility and plant availability were systematically increased.

One focus was on wear behavior and the service life of caster components such as the casting nozzle, conveyor belt, and moving side dams. Our findings were overwhelmingly positive. The newly developed inertization – from the tundish to the section downstream of the caster – ensures a minimal residual oxygen content before casting. That makes BCT® a truly unique solution.
