Primetals to Modernize CycloconverterDrive at SalzgitterFlachstahl
Salzgitter Flachstahl GmbH has commissioned Primetals Technologies with the replacement of the existing cycloconverter drive system for the crop shear
Salzgitter Flachstahl GmbH has commissioned Primetals Technologies with the replacement of the existing cycloconverter drive system for the crop shear installed on the finishing mill of the Salzgitter German production site. The aim of the project is to maintain the availability of the finishing mill by replacing the obsolete cycloconverter drive with a new cycloconverter drive. When replacing the existing cycloconverter drive system, the customer's request is realized to build the new system switchable in parallel to the existing cycloconverter in order to ensure a risk-free replacement with short downtime. The project is scheduled to be completed in November 2021. The scope of delivery of Primetals Technologies includes the complete electrical replacement of the cycloconverter. Further, the order includes the delivery of a new control room panel, the creation of additional visualization screens and diagnostic options, as well as the integration of the new drive system into the existing cutting sequence control of the finishing mill.
