A heating method that utilizes the principle of heat generation as an electrical phenomenon. It is also called electric heat for short. It has the following characteristics: heat can be generated not only from the outside but also from inside the object to be heated; it can heat uniformly or locally depending on the purpose, and it can also heat in a vacuum or high-pressure gas; it is easy to control the temperature; there is no exhaust gas or ash that is generated by combustion heating; and it can reach high temperatures of over 2000°C. In terms of applications, it is widely used in industry for electric steelmaking of special steel and ordinary steel, steel hardening, melting of iron for casting, drying of paint, and the manufacture of germanium and silicon crystals for transistors, while for general households it can be found in electric stoves, sheathed heaters, microwave ovens, etc. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
電気現象としての発熱原理を利用する加熱方法。略して電熱ともいう。外面からだけでなく被熱物内部から発熱させることができる,目的に応じ均一加熱も局部加熱も,また,真空,高圧ガス体中などの加熱も可能である,温度制御が容易にできる,燃焼加熱に見られる排ガスや燃えかすなどがない,2000℃以上の高温も得られる,などの特徴がある。応用面として,工業向けには,特殊鋼や普通鋼の電気製鋼,鋼の焼入れ,鋳物用鉄などの溶解,塗装乾燥,トランジスターなどの材料のゲルマニウム,シリコン結晶の製造などに広く利用され,一般家庭向けには,電気こんろ,シースヒーター,電子レンジなどが見られる。
