Abstract

PURPOSE: To enable a heating device, if stopped heating a material in a heating coil temporarily during normal operation, to be re-started satisfactorily without producing any reject by maintaining temperature of the heated material in the heating coil almost at the same condition as the temperature-ascending curve in the normal operation.
CONSTITUTION: In a heating device in which a material is heated along a locus 9 by supplying heating coils 1-1 through 1-7 with power through a power source transformer 6, a power-supplying source 5, a changeover switch 4, a transformer 3 and a power factor compensating capacitors 2-1 through 2-7, if it stopped heating the material in the heating coil, the power to be supplied to the heating coil is determined by a temperature being 50% of the temperature-ascending curve of all the heating coils. In other words, the temperature is maintained within the lower limit of the tolerable temperature at the top end section of the heating coil and also within the upper limit of the tolerable temperature at the rear end of the heating coil so that heating condition can be maintained within the tolerable temperature range at the time when the heating of material is re-started.
