The second strand of the continuous slab caster modernized by Primetals Technologies for German steel producer ArcelorMittal Bremen GmbH has now been brought into operation. The modernization included equipping the machine head of the twin strand casting plant with new molds as well as the DynaWidth and DynaFlex technology packages. The aim of the project was to increase the availability and reliability of the plant, and to further improve product quality. Modernization of the first strand was completed in October 2014. Operational experience shows that an annual total of almost 600 megawatt hours of electrical energy can be saved for the two strands.
