摘要： PROBLEM TO BE SOLVED: To control combustion of a furnace to control the temperature of an object to be heated to a desired temperature more highly accurately than before by appropriately correcting computation parameters for simulating the temperature of the object to be heated in the furnace. SOLUTION: Stray noise luminance based on burner flames and combustion gases is reduced to a practically negligible level, and the effect of stray noise luminance based on disturbance light from a ceiling surface 12a of a preheating zone 12 is estimated to determine the luminance I b (T s ) of spontaneously emitted light emitted from a slab 21 itself. The surface temperature T s of the slab 21 is computed on the basis of the determined luminance I b (T s ) of spontaneously emitted light. Parameters (a total heat absorption rate ϕ CG ) related to the surface temperature of the slab 21 in a numerical simulation model (a thermal conduction equation) is corrected through the use of the computed surface temperature T s of the slab 21 to control combustion of the heating furnace 10.

摘要： PROBLEM TO BE SOLVED: To calculate a stray light noise caused by a furnace wall by a simplest possible method without lowering accuracy as much as possible. SOLUTION: A radiation thermometer 100 is installed on a position facing to the surface of slab 21 from above a heating zone 13, and thermocouples 200 are scattered on a ceiling surface 13a of the heating zone 13. A temperature measuring object domain 210 determined based on installation positions of the thermocouples 200 and zones A-L determined by dividing the temperature measuring object domain 210 are defined. A stray light noise brightness is determined in each zone by using each temperature of the thermocouples 200, and a value determined by adding each determined stray light noise brightness in each zone is used as the stray light noise brightness of the whole zone. On the other hand, as for a domain on the ceiling surface 13a other than the zones, each stray light noise brightness is determined as a whole by using properly calculated temperatures. Then, a self-emission brightness emitted from the slab 21 itself is determined by subtracting the determined stray light noise brightness from the emission brightness acquired by the radiation thermometer 100.
