熱が必要である。In this method, an induction heating coil is installed on the conveyance line to locally inductively heat one end of the rough bar, thereby preventing a drop in temperature at the end. However, the thickness of the coarse bar,
The width varies depending on the product, and in order to efficiently locally heat only the ends, it is necessary to move the induction heating coil according to the width of the bar, or to adjust the gap between the coil and the bar according to the thickness. It is necessary to have it. On the other hand, non-oxidative heating is desired from the standpoint of upgrading products and improving yield. This requires heating in an inert atmosphere insulated from the atmosphere.

A cover 4 is provided on the inlet conveyance line 3 to the finishing rolling mill 2 to insulate the rough bar, which is the heating mill 1, from the outside air. This cover 4 is provided with a gas inlet 5 for filling an inert gas such as nitrogen gas into the cover. The outlet portion of the heated material 1 of the cover 4 is gas-sealed.

っている。A heater main body 10 is provided between the conveyance rollers 3a within the cover 4. The heater main body 10 includes a box-shaped frame 11, a box-shaped heating element 12 made of a conductive material such as carbon attached to the frame 11, and a size that surrounds the heated material 1. Frame 1 above surrounding
1 and a number of stages of induction heating coils 13 attached to the coil. On the other hand, on the entrance side of the cover 4, there is a heated material 1
A thermometer 6 is provided to measure the temperature distribution in the width direction. Then, based on the signal from the meter 6, the control device 7
The coil 13 to be used is selected and the power applied to the selected coil 13 is controlled via the coil 13.

１の端部は間接加熱されて、端部の温度が補償される。Then, an inert gas is sealed in the cover 4, and the temperature distribution in the width direction of the material to be heated 1 being conveyed is measured by the thermometer 6. Then, based on this measured value, a plurality of coils 1 provided surrounding the heating element 12 are controlled via the control device 7.
The coil to be used is selected from the width of 3, and the input power is controlled. As a result, the heating element 12 is locally heated, and the end of the heated material 1 is indirectly heated by the radiant heat from the heating element 12, thereby compensating the temperature of the end.
この場合カバー内には不活性ガスが封入されているので
