Submerged Arc Furnace Will Be Mainly Applied For Reduction Of Metallurgical Ore To Produce The Fesi, Femg, Fecr, Ferrotungsten, Simg And Titanium Slag Alloy, Which Will Be The Important Material For Metallurgical And Chemical Industries.

Electric arc furnace uses electricity as fuel source and utilizes the arc high temperature produced by electrode and furnace charge to heat and melt the furnace charge. It is widely using in production of normal steel, high quality carbon steel, various alloy steel, stainless, various ferroalloys. It is the key equipment in steel making factories, foundry factories, ferrous alloys making factories and etc.
