Furnace Introduction  

submerged arc 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.

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 throgh which one or more graphite 

electrodes enter the furnace. The furnace is primarily split into three sections 

The shell, which consists of the sidewalls and lower steel bowl.
