TEMPERATURE CONTROL METHOD FOR HEATING FURNACE

摘要

PROBLEM TO BE SOLVED: To correctly control combustion according to the change in the flame length which is changed according to the fuel flow rate. SOLUTION: Parameters in controlling a strip temperature are changed according to the fuel flow rate in the furnace temperature control by controlling the flow rate of the fuel burned by a burner 22 and in the strip temperature control for controlling the temperature of the strip 8 by controlling the furnace temperature.
