摘要： PROBLEM TO BE SOLVED: To make it possible to stabilize the temperature of a furnace in a short time when the temperature in heating zones in the furnace is changed to a low temperature, by a method wherein current conduction to a heater to raise the temperature in the zones is turned off extending over a specified time to set the temperature in the zones to a target temperature subsequent to a change on of the set temperature in the zones or the temperature in the vicinity of the target temperature. SOLUTION: An air blower unit is continuously operated from a state H of high set temperature T1 in heating zones in a furnace to reach a stable state K of the low set temperature in the zones via J during the change of the set temperature, and a hot air generating heater is completely turned off extending over a specified time (t). By controlling the air blower unit at the time of the change of the set temperature in such a way, the temperature change in the zones makes the outside air continue to flow in the zones by the air blower unit to reduce rapidly the temperature in the zones. After the temperature in the zones is reduced from a low set temperature T2 subsequent to the change of the set temperature to a low temperature by T3, current conduction to the heater is reopened to make the temperature in the zones come close to the target set temperature T2. As a result, the temperature of the furnace can be stabilized in the state K of the low set temperature in a short time.
