Electroslag melting furnace

Japanese: エレクトロスラグ溶解炉 - えれくとろすらぐようかいろ
Electroslag melting furnace

…In contrast, in furnaces that use consumable electrodes, the electrodes themselves are melted using the Joule heat or arc heat generated between the electrodes and consumed to participate in the smelting process. Examples of this type of furnace include vacuum consumable electrode arc melting furnaces and electroslag melting furnaces. The electrodes are melted successively from the tip by the Joule heat caused by the arc heat or the electrical resistance of the molten slag, and impurities are removed as they drip through the vacuum or molten slag, producing a high-quality ingot in a water-cooled mold. …
