ELECTRIC RESISTANCE FURNACE

摘要

A furnace for melting metals, maintaining them in a melted condition and producing alloys, particularly of non-ferrous metals, by direct heating of the melt with non-metallic heating elements. The described furnace has high capacity and simple design and enables series connection of two or more furnaces to the electric supply with the selection of a suitable electrode the alloy components may be melted directly in the crucible. In the furnace chamber there is at least one heating element in the shape of a vessel. A current supply electrode is positioned within the heating element and is connected electrically to it by a metal within the heating element. Another body of melted metal is in the furnace chamber in contact with the walls and bottom of the heating element. Either body of metal may constitute the furnace charge.
