ArcelorMittal Bremen GmbH is a flat steel manufacturer and produces steel goods, mainly for the automotive and construction industries, via the integrated blast furnace-converter route. The company operates a twin-strand continuous slab caster with a production capacity of almost four million tonnes per year, on which slabs up to 2.67 meters wide are produced. The casting plant was built in 1973 by the former VOEST-ALPINE industrial plant construction company, fully renovated by third-party companies in 1991, and modernized in 2005.

 

To meet the higher demands of ArcelorMittal Bremen regarding the availability and reliability of its casting plant, Siemens is supplying rugged SmartMold cassette molds with easily replaceable copper plates and narrow sides. The DynaWidth technology package ensures dynamic yet precise setting of the slab width at maximum casting speed. The DynaFlex hydraulic mold oscillator adapts the oscillation parameters flexibly to the prevailing operating conditions. The new equipment is designed in such a way that the existing steel structure of the two strands does not have to be modified, thereby reducing construction costs and shortening the downtime necessary for the conversion work.
