(Usiminas) has awarded the contract for the replacement of BOF converter #5 of BOF Shop #2 at their 4.8 Mt/a Ipatinga integrated steelworks to Danieli Corus.

New converter

The new 180-t converter will be equipped with the Danieli-patented suspension system based on a vertical Lamella arrangement, in combination with horizontal Daniella elements, an air-cooling system for the barrel part of the vessel, and water–based cooling for the vessel’s top cone.

A Q–Temp 2.0 temperature monitoring system and EIC/automation packages will also be installed as part of this revamp project.

The first heat with the new converter is scheduled for 2023.
