Abstract

PURPOSE:To enable to estimate a heating completion time of an annealing furnace in an extremely precise manner by preparing a regression line relating to a time until a lowest temp. in a coil is reached to a target value based on static and dynamic factors. CONSTITUTION:From dynamic and static factors such as a bell temp., a bell throwing amount, a base fan capacity, a total spacer thickness, a coil width, a coil weight, a charge weight or the like, about a time until a lowest temp. of a coil in each step is reached to a target temp., a regression line is prepared. In a furnace, coils 1-4 are stacked stepwisely through spacers 5. A furnace temp. controller 12 operated in response to output of a bell thermometer 11 is provided and a fuel valve 14 is adjusted according to comparison result with a reference value of a furnace temp. setting device 13 to control a burner 15. Thereby, a furnace temp. is varied to control a highest temp. of the coils 1-4 so as to adjust to alpha'.
