Abstract

PURPOSE:To keep suitable heating state without decreasing conveying speed, by controlling respectively the heating means at the upper stream and at the downstream in accordance with the intermediate temp. of the material to be heated which is detected between plural heating means after the start of heating of traveling material to be heated. CONSTITUTION:Before the arrival of the top of an electric resistance welded pipe 10 at the inlet side of a continuous annealing apparatus is detected 38, the set value for applied voltage calculated by control unit 46 for heating is set as an initial value for respective electric power sources 41-44 for induction heating coils 11-14. When the top of the pipe 10 is detected 38, the coils are lowered in order beginning with the coil 11 in accordance with the passage of the pipe 10 under the coils 11- 14. The unit 46, after the coils 11 and 12 are lowered, receives the signals obtained by averaging 62 the intermediate temps. of a detector 28 by synchronizing the output signals of the speed detector 36 for intermediate temp. to make feedback signals. In the first and the second arithmetic units 51, 52, PID control is performed from the initial state in accordance with previously set feedback coefficient.
