Submerged arc furnace¡ait¡¡¥s also known as electric arc furnace or resistance electric furnace. It is mainly used to reducing smelting ore, carbonaceous reducing agent and solvent etc. Mainly adapts to production of ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, silicon manganese alloy and other ferrous alloys, it is an important smelting furnace in metallurgical industry for production of industrial raw materials and calcium carbide and so on chemical raw materials. The working character is to use carbon or magnesia refractory materials as furnace lining, use self roasting electrode. Electrode inserts into the materials inside the furnace for submerged arc operation, using arc energy and current through the materials, and due to the resistance of the materials and produce energy to melt metal. It¡¡¥s a kind of industrial furnace which is worked continuously, charged material in succession, and tapped out metal or slag in intermittent. Capacity:3000kva-33000kva, smelting different ferroalloy by ores.
