れないなどの欠点があった。Conventionally, in a t)j conduction heating device, in order to suppress the heat radiation of the heated material, a heat insulating member made of a refractory material in a cylindrical shape is provided on the side of the heating coil from which the material to be heated is carried out. was. Therefore, it takes time for the heat retaining member to absorb the radiant heat of the heated material and rise to a predetermined temperature. For this reason, there is a drawback that the heat retaining effect is slow to be exerted, and furthermore, the heat retaining member must be thick in order to be effective.
この発明は上記に鑑みてなされたもので、加熱コイルの

効果を向上させるようにした誘導加熱装置を提供する。The present invention has been made in view of the above, and provides an induction heating device that improves the heat retention effect by providing a heat retention member that generates heat due to leakage magnetic flux of a heating coil.
以下１図について説明する。第、１図において。Figure 1 will be explained below. In Fig. 1.

It is a combination of a non-magnetic metal and a refractory material, or a non-magnetic metal and a heat insulating material, and is configured to have approximately the same diameter as the refractory member (3).

上記実施例と同様の効果を期待できる。If you use the above-mentioned heat-retaining member (4-hole magnetic gold), the heat-retaining member (
4) becomes overheated and melts away. Thermal insulation material shown in Figure 2 (
6) shows a case in which a cutout part 0 is provided at the bottom and the entire length cannot be made into a cylinder shape due to the rollers that convey the material to be heated (1), and the heat insulating member (7) in Figure 8 is cut out over the entire length. &(
7a) is provided to prevent overheating if the magnetic flux (5) passing through it is too strong. Thermal insulation member (3) in Figure 4
In this example, a heat insulating material (8b) is placed on the outside of a non-magnetic metal shrine (8a), and this type can be used most commonly. In addition, it is also possible to place a fireproof material or a heat insulating material on the inside of the heat insulating member, which faces the material to be heated.Furthermore, it is possible to arrange a fireproof material or a heat insulating material on the inner and outer peripheries of a non-magnetic metal core. too,
The same effects as in the above embodiment can be expected.
