Modernizing cycloconverter drive of plate mill at SIJ Acroni in Slovenia

VarioVerter cycloconverter controller from Primetals Technologies. Two systems will be installed at SIJ Acroni in Jesenice, Slovenia.

Installing the new VarioVerter also takes account of a request from the customer: should a synchronous motor be damaged, the customer would later like to have the opportunity of temporarily running the plate mill with a DC motor using the supplied drive control components.  

Primetals Technologies’ scope of performance includes supplying two VarioVerter cycloconverter controllers, replacing the field control units, electrical assembly, and integration into the plate mill’s existing basic automation control system, thereby largely leaving the interface situation unchanged.

SIJ Acroni is Europe’s leading producer of stainless quarto plates. The company also specializes in electric and custom steels, which are sold as hot and cold-rolled coils, heavy plates and cold-formed sections, mainly for use in special niche products. The SIJ Acroni plant is located in Jesenice, about 60 kilometers northwest of Ljubljana, the capital city.
