Submerged arc furnace

Product Detail

Usage


   Submerged Arc Furnace is used for many kinds of ferroalloy smelting, including Ferrotungsten, High-carbon Ferromanganese, Ferrosilicon, ferrochrome, Ferronickel and Silicon, Calcium Carbide, Corundum, Yellow Phosphorous, etc.The nomenclature submerged means that the furnace's electrodes are buried deep in the furnace burden. A reduction reaction takes place near the tip of the electrodes to facilitate the furnace's process.




Furnace structure & main Components:

    A submerge arc furnace's shell or casing is fabricated from steel. The lower part is lined with hard blocks of strongly calcined carbon, and the upper part with firebrick. The floor and lower section of the furnace are water-cooled. Three electrodes are placed at the angles of an equilateral triangle with rounded corners. These furnaces can be equipped with either pre-baked electrodes or Söderberg electrodes. The Söderberg electrodes are heated by the electric current and the furnace heat, then baked solid in the region of the contact clamps. The electrode must become baked solid over its entire cross section (inside the charge) when it is fed downwards to compensate for its consumption in the furnace (which is a few centimeters per hour).
