thyssenkrupp Taps Primetals Technologies to Modernize Slab Sizing Press

The company said the modernization will include an upgrade of the electrical and drive systems with a new cycloconverter for the main press motor, low-voltage multidrive converters, and DC converters for the pinch rolls, gap adjustment and roller tables. Implementation and start-up services will also be included. 

All converter technologies for the main drive and several supporting drives will be renewed while most existing transformers and motors will be retained. This will significantly reduce capital expenditure, the company said. 

Primetals Technologies will also design a custom cooling solution for the drive room based on a closed-loop air-to-water system at the drive cabinets. The setup is estimated to provide efficient cooling and improve energy efficiency. An arc fault protection system will also be installed to extinguish arc flashes and enhance safety for personnel and equipment. 

The company said start-up is scheduled for the third quarter of 2026.
