Abstract
PURPOSE:To control temperature of a material to be heated at a specified level, by making a cascade control on the radiation amount after selecting zones in accordance with the heating stipulation of the material to be heated. CONSTITUTION:When strip material W is treated at nonoxidation heating furnace 1 of continuous plating equipment, number of controlling zone is calculated by giving data of heating stipulation, such as dimension of material to be heated, etc., to computor 32. When, for example, the signal of controlling zone is [3], change- over switch 34 is switched by distinguishing device 33 and heating of the fourth zone 14, the fifth zone 15 is stopped, and zones from the first 11 to the third 13 are selected as the controlling zone. In these zones, the cascade signal of material temperature control device 7 is given to each heating amount control device 21, and temperature of material can be controlled at a specified level by cascade controlling the heating amount of burner 3 is accordance with the output signal from infrared thermometer 6. Accordingly evil influences accompanied to put on and extinguishing of burner is eliminated.
