Furnace introduction
Submerged melting furnace is also known as electric arc furnace or resistance furnace. It is
mainly for production of ferrosilicon, ferromanganese, ferrochromium, tungsten iron, silicon
and mangansese ,ferrochromium, tungsten iron, silicon and manganese alloy and other
ferroalloy, all above are important industrial raw materials and calcium carbide and other
chemical raw materials in metallurgical industry.
Product Description
Submerged arc furnace is also known as electric arc furnace or resistance electric furnace. It is mainly
used to reduce smelting ore, carbonaceous reducing agent and solvent etc. Mainly adapt to production
of ferromanganese,ferrochorme, silicon manganese alloy and other ferrous alloy.
