The main method of ferroalloy production: classification by heat source. Heating method. Heat electrothermal smelting process is mainly electricity, carbonaceous reducing agent oxide ore using a continuous operating process and in reducing electric furnace. Silicon thermal power. Heat silicon thermal power smelting process is mainly electricity, heat remaining barium calcium aluminosilicate quality new time for the release of the silicon oxide, silicon (ferrosilicon, silicon manganese alloys and intermediate products of silicon-chromium alloy) as a reducing agent in Ore oxide. Production is carried out intermittent operations in the refining electric furnace. The main method of ferroalloy production: classification by operating methods and processes. No slag. No slag smelting iron alloy is the use of a carbonaceous reductant, silica or reconstituted alloy as raw materials, continuous smelting reduction furnace new Si-Al-Ba-Ca prices, products such as ferrosilicon, industrial silicon, silicon-chromium alloy. There slag. There ferroalloy smelting slag in the reduction furnace or electric furnace refining, choose a reasonable residue type system and alkalinity production ferroalloys, iron slag than by its different varieties and material condition of the corresponding use of other factors, is generally 0.8 to 1.5.
