PROBLEM TO BE SOLVED: To provide a method for controlling furnace temperature in a continuous-type heating furnace, with which the quality related to the heating can be improved while accurately heating a steel material to be a targeted temperature rising pattern.SOLUTION: In the method for controlling furnace temperature, a material to be heated in the continuous-type heating furnace is heated to a targeted extracting temperature. Based on the targeted extracting temperature given to each material to be heated, a targeted soaking degree at the extracting time and the surface temperature limitation as the upper limited temperature on the surface of the material to be heated in the heating temperature rising process, when the furnace temperature setting value in each combustion zone is obtained so that an exhaust gas heat loss becomes little, and with the surface temperature limitation of the material to be heated as a constrained condition, the most suitable furnace temperature in each combustion zone is obtained for every material to be heated with a mathematical programming method to decide the setting furnace temperature in each combustion zone from each most suitable furnace temperature thereof. |
