Outokumpu to Modernize its Cycloconverter with Primetals Technologies

Finnish stainless steel producer Outokumpu will replace its existing cycloconverter drive control system and power section for stand No. 2 at its stainless direct-reduction, annealing, and pickling line (DRAPL) in Tornio, Finland.

Production Line Availability

The project aims to increase the availability of the production line, ensuring the drive system meets future spare-part supply conditions. Outokumpu Oyj prioritized an adaptable replacement concept and close collaboration based on mutual trust regarding service issues and improvements at the existing DRAPL, when selecting Primetals Technologies as a supplier for the revamp project.

An installation of electrical equipment, implementation and adaptation of Level 1 software for the new drive system, a new controller and power sections for the cycloconverter, and an upgrade to the excitation unit and auxiliary system make up the scope of the revamp project. Integration into the existing basic automation control system will also leave the interface unchanged.

Primetals Technologies will upgrade the drives for stand No. 2 at Outokumpu’s stainless direct-reduction, annealing, and pickling line at the steel plant in Tornio, Finland.
