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.

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.
