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 :

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

The hearth, which consists of the refractroy that lines the lower bowl. 

The roof, which consists of the refractory-lined or water cooled, and can be shaped as a section 

of a sphere, or as a frustum . The roof also supports the refractory delta in its center, through 

which one or more graphite electrodes enter.

The hearth, which consists of the refractory that lines the lower bowl. 

The roof, which may be refractory lined or water cooled , and can be shaped as a section of 

spherere, or as a frustum ( conical section), the roof also supports the refractory delta in its 

center, through which one or more graphite electrodes enter. 

Application of Submerged arc furnace  

Arc furnace is using electricity as the fuel source, and utilizeds the arc high temperature produced by 

electrode and furnace charge to heat and melts the furnace charge.  It is widely using in the 

production of normal steel ,high quality carbon steel, various alloy steel, stainless, various 

ferroalloys. It is the key equipment in steelmaking factories. foundry factory, ferrous alloys 

making factories and etc.
