Title (EN) DC ELECTRIC FURNACE
(FR) FOUR ÉLECTRIQUE CC
(KO) DC전기로
Abstract:
(EN) Disclosed is a DC electric furnace, which is an electric furnace using a DC electrode, comprising: a body having a bottom surface, which has a taphole formed thereon, and the body providing an inner space, in which scraps are inserted; a lower electrode mounted on the bottom surface of the body; and a bottom blowing means provided on the bottom surface so as not to interfere with the lower electrode, thereby blowing a gas into the inner space of the body.
(FR) La présente invention concerne un four électrique CC, qui est un four électrique utilisant une électrode CC, comprenant : un corps ayant une surface inférieure, sur laquelle est formé un trou de coulée, le corps formant un espace interne, dans lequel des rebuts sont insérés ; une électrode inférieure montée sur la surface inférieure du corps ; et un moyen de soufflage inférieur disposé sur la surface inférieure de manière à ne pas interférer avec l’électrode inférieure, de manière à souffler un gaz dans l’espace interne du corps.
(KO) 직류전극을 이용하는 전기로로서, 출강구가 형성된 바닥면을 가지며, 스크랩이 장입되는 내부공간을 제공하는 본체; 본체의 바닥면에 장착되는 하부전극; 및 하부전극과 간섭이 일어나지 않는 바닥면에 구비되어 본체의 내부공간에 기체를 취입시키는 저취수단;을 포함하는 DC전기로가 소개된다.
