...A method of electric heating that uses the heat of an arc discharge. An arc is a discharge phenomenon in which electrodes are connected by an arc column (positive column) consisting of a plasma of electrons and ions, and the cathode point, anode point, and arc column reach high temperatures of 3000 to 6000 K. There are two methods for utilizing this heat: (1) direct arc heating, in which the arc current flows through the object to be heated, and (2) indirect arc heating, in which the arc current does not flow through the object to be heated, and the arc heat is transferred to the object by radiation. *Some of the terminology that refers to "arc pillars" is listed below.

…アーク放電の熱を利用する電気加熱の一方式。アークは電極間が電子とイオンのプラズマからなるアーク柱(陽光柱)で結ばれた放電現象で,陰極点,陽極点およびアーク柱は3000~6000Kの高温になっている。この熱を利用するのに,(1)アーク電流が被熱物中を流れる直接アーク加熱,(2)アーク電流が被熱物中を流れず,放射によってアーク熱が被熱物に伝えられる間接アーク加熱の2方式がある。… ※「アーク柱」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
