Method for setting steel stock discharge temperature of heating furnace in hot rolling line

摘要

A method for setting a steel stock discharge temperature of a heating furnace in a hot rolling line in which both fuel unit consumption in the heating furnace and that in a rolling line are calculated to obtain a total fuel unit consumption in the entire line, and an optimum discharge temperature is calculated so as to satisfy a metallurgical discharge temperature restrictive condition and minimize the above total fuel unit consumption and the optimum discharge temperature is used as the steel stock discharge temperature.
