PROBLEM TO BE SOLVED: To provide a method for controlling the temperature of furnace by which an object to be heated can be heated in a good temperature distributing state containing less heating unevenness in a furnace provided with a heat storage burner. SOLUTION: In a method for controlling the temperature of furnace in which the temperature of a furnace having at least a pair of heat storage burners each constituted by combining a burner with a heat accumulator is controlled by discharging the exhaust combustion gas of the combustion-side heat storage burner to the outside through the exhaust-side heat storage burner by switching the burners to the combustion side and exhaust side in a prescribed switching cycle and, at the same time, maintaining the temperature in the furnace at a prescribed value by adjusting the combustion time of each burner in the switching cycle time while the combustion amount of each heat storage heater is maintained at a prescribed value, the combustion time Tb of one B of the paired heat storage burners is made longer that that of the other burner A. |
