Primetals Technologies Receives Final OK on BOF Upgrade
According to Primetals Technologies, the project entailed installation of a new vessel, trunnion ring, slag shields and its vessel suspension system, Vaicon Link. It also replaced the tilting drive and AC motors. Mechel separately installed a new cooling stack and the associated offgas cleaning plant.
The project increased capacity by raising the tapping weight to 160 metric tons and by reducing tap-to-tap times.
Primetals Technologies was responsible for the basic and detail engineering, and supplied core components. It also supervised the installation and commissioning.
