Abstract

No. 2 Steel-making Plant of Muroran Works, Nippon Steel Corporation has developed a new technique of L.D. converter operation, that is, sampling and temperature measurement has come to be executed by sub-lance with a unique senser without tilting the vessel, which is named “Quick Tapping”. Effects of Q.T. operation are as follows. (1) By the elimination of temperature measuring and sampling operation, considerable labor can be saved. (2) By the reduction in temperature measuring and sampling time, increase in production can be expected. (3) As no molten steel flows out when temperature measuring and sampling are executed, reduction in yield can be prevented. (4) Since the molten steel stays in the furnace for a shorter time, the life of the furnace can be prolonged. (5) As the temperature of the refract-tories does not drop the target tapping temperature can be lowered. (6) There is no disastrous accident which is related to safety and tilting operation. Q.T. operation was put into practice in November of 1972 and completed for all heats in September of 1973. Q. T. operation has largely contributed to high productivity. No. 2 Steel-Making plant made a new record of 111 heats per day in October 16th in 1973.
