Since April 1970, a ladle refining furnace (ASEA-SKF process) with 100 t capacity has been operating at Mizushima Works of Kawasaki Steel Corp. Through the LD-LRF process, i.e., a combined process of a 180 t LD converter with ladle refining furnace, high quality steels for forgings and extra heavy plates have been produced successfully instead of using the conventional electric arc furnace-degassing process. This plant can treat mother metal from 100 t (half heat of LD converter) to 30 t (electric arc furnace). The typical operational pattern of this process consists of the carbon dioxidation at degassing period and the sequent aluminium deoxidation with effective induction stirring. The hydrogen content is effectively reduced at the rimmed or semi-killed state. All this paper, some operational results, especially the deoxidation behavior during induction stirring and hydrogen removal technique are reported.
