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.

Construction 

Submerged arc furnace used for steelmaking consists of a refractory lined vessel, usually water cooled in large 

size, covered with a retractable roof, and through which one or more graphite electrodes enter the furnace. 

The furnace is primarily split into three sections .
