thyssenkrupp Steel has contracted Primetals Technologies to modernize the slab sizing press at its hot-strip mill No. 2 in Duisburg, Germany. Previously, Primetals Technologies had successfully upgraded its hot-strip mill No. 4.
The overhaul includes a full upgrade of the electrical and drive systems, with a new cycloconverter for the main press motor and low-voltage multi-drive converters and DC converters for supporting drives.
Most existing transformers and motors will be retained, reducing capital expenditure. Primetals will also implement a tailor-made cooling solution and an arc fault protection system for enhanced safety.
This modernization aims for increased equipment availability and a secure spare parts supply. Startup is planned for the third quarter of 2026.
