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 barium calcium aluminosilicate Deoxidants plant products such as ferrosilicon, industrial silicon, silicon-chromium alloy. There slag. There ferroalloy smelting slag in the reduction furnace or electric furnace refining barium calcium aluminosilicate Deoxidants price, 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 , typically 0.8 to 1.5. The main method of ferroalloy production: classification by operating methods and processes. Intermittent smelting. Intermittent concentrate smelting charge is added to the smelting process or batch furnace. Generally divided into two periods of melting and refining, in the melting of the electrode is buried in the charge; and refining of Arc is exposed, and the refining of the EAF is barium calcium aluminosilicate Deoxidants exposure, refining is completed, discharge alloys and slag, and then proceed to the next load of new material melting furnace.
