けられている。 The electric oven of the present invention is shown in FIG. 1 is a main body equipped with a control circuit etc. inside, 2 is a heating chamber provided in this main body and whose front opening is closed by a door 3 which can be freely opened and closed, and a sheathed heater as a heating component is installed at the top. 4 is provided. The sheathed heater 4 includes a coiled heating wire 1 as shown in FIG.
1. Electrical insulation powder 12 made of magnesia powder,
and a metal pipe 13 made of heat-resistant steel such as SUS321 or Incoloy 800, and a ceramic coating layer 14 made of a SiO 2 -BaO-based heat-resistant hollow material is provided on the surface of the metal pipe 13.
シーズヒータが使用される温度条件が約800〜
850℃になる為ホーロ加工は少なくとも900℃以上
で焼成されるホ−ロ組成である。 The temperature conditions under which the sheathed heater is used are approximately 800°C and above.
Since the temperature is 850℃, the enameled material is fired at a temperature of at least 900℃ or higher.
