Furnace introduction
Smelting melting furnace, is also known as electric arc furnace or resistance furnace, it
is mainly used for the reduction of smelting ores, carbon reductants and solvents etc.
It is mainly for production of ferrosilicon, ferromanganese,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.
