とは困難でない。 In addition, in the above-mentioned configuration, cooling water is also supplied to the three unused induction coils 11, and the pump for supplying the water requires extra power, but this will be described below. There are advantages such as: That is, when the induction coil 11A is switched as described in the above operation, the current to this coil is automatically cut off at the same time, but cooling water is not supplied to the induction coil 11A for a certain period of time even after the current is cut off. This is due to the problem that if the supply is not carried out, the temperature will rise for a certain period of time after electricity is cut off, shortening the life of heat-resistant materials, etc.
Naturally, it is not difficult to supply cooling water only to the induction coil 11 in use by using a switching valve or the like.
又、誘導コイル１１は４個設けたが、回転軸を

In particular, the desired induction coil is arranged to face the billet conveying device, so even if a plurality of induction coils are provided, the mechanism for replacing the induction coil is simple. Since it is not placed on top, it does not require a large space.
