PROBLEM TO BE SOLVED: To provide a method and a device for controlling the furnace temperature of a continuous annealing furnace capable of enhancing the energy efficiency of the continuous annealing furnace and enhancing the responsiveness to the change of the furnace temperature. SOLUTION: In the furnace temperature control method to control the temperature in a furnace zone of a continuous annealing furnace to a predetermined value, exhaust gas generated by a heating burner of a heating zone 3 of a continuous annealing furnace is heated by a hot gas generator 21 to adjust the sensible heat of exhaust gas, the exhaust gas and the atmospheric gas in an overaging zone 7 are heat-exchanged by a heat exchanger 23 to control the furnace temperature in the overaging zone to a predetermined value.
