ABSTRACT:
A programmed temperature controller including a difference detector which detects a temperature difference .DELTA.T between a quick-response temperature TC2 and a slow-response temperature TC3 at a quickly-responding portion and a slowly-responding portion of a workpiece (e.g., on the surface and core portions thereof). Also included is a comparator which compares the temperature difference .DELTA.T against an allowable difference limit preset by a difference setter. When the temperature difference .DELTA.t is found to be outside the allowable difference limit, a slope operator is actuated by the comparator, so as to calculate a slope of temperature change with respect to time of a program pattern PP which keeps the temperature difference .DELTA.t within the allowable limit. The above-mentioned slope in the program pattern PP is modified to the calculated value, and the temperature difference .DELTA.T is maintained within the allowable difference limit.
