Mineral heat furnaces are mainly used for refining ores, reductants and other raw materials for electric furnaces, focusing on the production of various types of iron-based alloys, such as ferrosilicon, industrial silicon, ferromanganese, ferrochrome, ferrotungsten, silicomanganese alloys, and ferronickel, etc., which are widely used in metallurgical industry to enhance the performance of metal materials.

Modern mineral heat furnace adopts fully enclosed furnace type, the main equipment consists of furnace body, low smoke hood, smoke exhaust system, short net, electrode system, hydraulic system, slag discharge system from steel, furnace bottom cooling system, transformer and so on.
