Abstract: According to an embodiment of the present invention, a heat treatment system is provided. The heat treatment system includes a heating unit, a heat treatment condition memory unit, a power change model memory unit, a heat treatment change model memory unit, a heat treatment result reception unit, and an optimal temperature calculation unit. In the heat treatment system, the optimal temperature calculation unit calculates the power of the heating unit at a corresponding temperature based on the model stored in the power change model memory unit and the calculated temperature, and an optimal temperature is a temperature at which a heat treatment result is closest to the targeted heat treatment result within a range in which the calculated power of the heating unit is not saturated.

Abstract: A control unit can select a large-number control zone model in which the number of control zones, which are independently controlled, is large, and a small-number control zone model in which the number of control zones, which are independently controlled, is small. When a temperature is increased or decreased, the control unit can select the small-number control zone model so as to control, based on signals from temperature sensors of the respective control zones C1 . . . C5 whose number is small, heaters located on the respective control zones C1 . . . C5. When a temperature is stabilized, the control unit can select the large-number control zone model so as to control, based on signals signals from the temperature sensors of the respective control zones C1 . . . C10 whose number is large, the heaters located on the respective control zones C1 . . . C10.
