Abstract

An induction heater (1) comprises an inductor (6) which can adjust the inductor gap (H), i.e. the interval of the opening (3) of a C-shaped core (2), upper and lower core legs (4a, 4b) of the opening (3) being wound with heating coils, a means (15) for detecting the electric power of the measured heating coil as a measurement of electric power, a heating condition setting means (11) for setting atarget electric power depending on the optimal heating conditions of the heating coil, a means (16) for converting a target electric power into an optimal inductor gap value and converting the measurement of electric power into a measurement of inductor gap, a means (17) for calculating a gap deviation, and a gap motor control means (19) for controlling a gap motor (19) so as to adjust the inductor gap based on the gap deviation.

Description

technical field [0001] The present invention relates to an induction heating device for heating the left and right ends of a conveyed heated material in a hot rolling facility. Background technique [0002] Generally speaking, in hot rolling equipment, the workpiece to be heated is continuously conveyed after being heated to a predetermined temperature in advance, and rolled sequentially by multiple rolling mills to form a thin plate. During the transport of the heated material, heat is gradually dissipated from the end portions on both sides, and there is a problem that the temperature of this portion gradually decreases compared with that of the central portion. Rolling in a state in which the temperature of the end side drops and the overall temperature is uneven will cause the quality of the rolled steel plate to be unstable, the hardness of the side end will increase, cracking of the heated part, and partial wear of the roll of the rolling mill will occur. question. T...
