Installation of Vaicon Slag Stopper at U. S. Steel - Great Lakes Works

摘要

To improve efficiency and reduce conversion costs, United States Steel Corporation installed the pneumatic slag retention system from Primetals Technologies on the two 200-ton basic oxygen furnaces operated in the meltshop at Great Lakes Works. Expected benefits from this project include reduced slag carryover, improved alloy yield and increased steel quality. The Vaicon stopper went into operation in the summer of 2018. The paper describes the equipment, operational results and benefits achieved. In the last part of the paper, an outlook on a new generation of slag stopper is presented.
