Refining practice and application of the ladle furnace (LF) process in Japan.
Transactions of the Iron and Steel Institute of Japan, 1984 Since 1971, Daido Steel Co., Ltd. has developed the LF process, a ladle refining process which depends primarily on slag refining, aiming an ideal performance of reduction refining instead of electric arc furnace. The main feature of this ladle technology exists in refining under non-oxidizing atmosphere and acceleration of slag-metal reaction through ...
