For furnaces that require high temperatures, special heating wires such as Kanthal wires are used. is normal. As high-tech industries such as ceramics become more popular, temperatures up to 1100°C are required. Therefore, heating materials that use carbon or the like and use induction heating methods have also appeared. However, the high temperature furnace of nearly 2000℃,
9 The inventors developed a simple and efficient high-temperature electric furnace using high-frequency current, which was extremely difficult and expensive.

コイル１を設置する。(Means for solving the problem) As a principle, as shown in Figure 1, high frequency current
When a material that is easily subjected to induction heating, such as iron [2] is used as the heating material, and a spiral-shaped planar heating coil 1 for heating the material is induction heated in close proximity to the surface of the iron plate, it is efficiently heated. I can do it. 3 is a high frequency current generator. Specifically, Figure 0, which will be explained with reference to Figure 2, shows a cross section of the furnace.A U-shaped iron plate 2 is installed along the inner wall of the furnace 4, which is thermally insulated with heat-resistant material. Install the type water cooling coil 1.
炉壁のこの部分は、出来るだけ薄く形成する、誘導加熱
用のコイルと鉄板の距離が小さい程、効率的であるが余
り薄くすると熱の放散が多くなる。This part of the furnace wall is made as thin as possible, and the shorter the distance between the induction heating coil and the iron plate, the more efficient it is, but if it is made too thin, more heat will be dissipated.
このコイルに１０ Ｋ Ｃ乃至２００ Ｋ Ｃの高周波
電流を流すと、誘導によって鉄板２は加熱され炉の温度
は上昇する。When a high frequency current of 10 K C to 200 K C is passed through this coil, the iron plate 2 is heated by induction and the temperature of the furnace rises.

炉壁の耐える温度迄、高温に昇温することが出来る。When iron is used as the material for the heating plate 2, the temperature of the furnace is 1000.
If it is possible up to "C", use carbon, zirconia, stainless steel, molybdenum plates, etc. for higher temperatures.This heating plate should have a structure that can be replaced freely.By this method,
The temperature can be raised to a high temperature that the furnace walls can withstand.
