In the BOF-type furnace for hot metal dephosphorization at Kakogawa Works, it is difficult to remove the metal adhering from the slag line part to the throttle part of the furnace, meaning that the treatment ratio has decreased. In addition, slopping was promoted by the decrease in furnace internal volume due to adhesion of the metal, and this resulted in a decrease in iron yield. In this paper, the focus of the report is on the removal method of adhered metal by utilization of the slag with high temperature using post combustion of CO gas in foaming slag.
