EAF-16500KVA Submerged Arc Furnace for Sale

Introduction to Submerged Arc Furnace: Submerged Arc Furnace is mainly used for reducing and smelting ore, carbonaceous reducing agents and solvents, and other raw materials. It mainly produces ferrosilicon, ferromanganese, ferrochromium, ferrotungsten, silicon-manganese alloy, and other ferroalloys, which are important industrial raw materials in the metallurgical industry and chemical raw materials such as calcium carbide.

Its working feature is to uses carbon or magnesia refractory materials as the furnace lining and use self-cultivating electrodes.

The electrode is inserted into the furnace material for submerged arc operation, using the energy and current of the arc to pass through the furnace material, and the energy generated by the resistance of the furnace material to smelt metal, feeding successively, intermittently tapping iron slag, an industrial electric furnace that operates continuously.
