PROBLEM TO BE SOLVED: To provide a furnace temperature control method or the like in a continuous heating furnace capable of effectively inhibiting superheating without accompanying large-scale remodeling of equipment and without needing pitch-down. SOLUTION: In this method of controlling furnace temperature in the continuous heating furnace 100 having a plurality of continuous heating zones, one heating zone is divided into a plurality control zones A, B respectively having at least one combustion gas burner, the correlation of furnace temperature of the control zone A affected by furnace temperature of the control zone B, gas flow of the combustion gas burner mounted in the control zone A, and the furnace temperature of the control zone B is calculated in advance, a set furnace temperature of each control zone is temporarily determined, the temporary set furnace temperature of each control zone is reset on the basis of the correlation calculated in advance, and the gas flow of the combustion gas burner mounted in each control zone is controlled to achieve the reset furnace temperature of each control zone.
