Four electrode DC metallic silicon submerged arc furnace 100~16000kVA This DC submerged arc furnace can use raw materials such as silica, silica slag, and silica mud to smelt metallic silicon. 10500kW·h/ t metallic silicon Green and energy-saving, stable and reliable The metal silicon smelting DC submerged arc furnace is an equipment used to produce metal silicon. Silicon metal is an important metallurgical raw material widely used in industries such as ferroalloys, casting, and chemical engineering. Metallic silicon smelting DC submerged arc furnace are usually composed of furnace body, combustion system, cooling system, etc. The furnace body is generally made of refractory materials, which can withstand high temperatures and chemical corrosion. The combustion system is used to provide the high temperature required in the furnace, and common fuels include coal, coke, natural gas, etc. The cooling system is used to control the temperature of th…
