必要となるなどの問題点があった。The material having such a material has a thermal conductivity of 14 to 17 Kcal / m.s. h. Since the temperature conductivity is as low as 0.016 m 2 / h, The temperature distribution on the entire plate surface is not good, such as red heat only near the sheathed heater. 2. Since the thermal conductivity and the thermal conductivity are low, a large proportion of heat is dissipated except on the plate surface, resulting in poor thermal efficiency.
3. When the red-hot plate is cooled rapidly, the plate surface is deformed. 4. SUS at high temperature (500 ° C or higher)
A temper color that is peculiar to the material is generated and the appearance becomes unsightly.
Further, the generation of oxide scale of this SUS material deteriorates the corrosion resistance. Therefore, there is a problem that it is necessary to take measures such as applying heat resistant paint.

的熱伝導の対応がはやいため変形も少なくなる。With the above structure, the Ni material on the plate surface has good heat resistance and corrosion resistance, and even when the plate is heated to a high temperature, it forms a nickel oxide layer with a uniform appearance color (gray green) and far infrared rays. The effect can be expected. It also has a high corrosion resistance and little thermal deterioration. The Cu material, which is the intermediate layer of the three-layer clad, has a thermal conductivity of 0.404 m 2 /
Since h is very good, the heat source emitted from the heat generating member (hereinafter referred to as the sheath heater) is conducted to almost the upper part and the temperature distribution in the entire plate is made uniform. In addition, even if it is rapidly cooled, it is less likely to be deformed because the entire heat conduction is quick.
