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 the quality of barium calcium aluminosilicate exposure, while refining barium calcium aluminosilicate of EAF is exposed, refined finished silicon the price of aluminum, barium, calcium, alloy and slag discharge, and then proceed to the next load of new material melting furnace. Ferroalloy production methods: heating method is the production of ferro-alloys (high-carbon alloy), the main method; silicon thermal power is reduced ore in an electric furnace, silicon oxide or slag wholesale (such as ferrosilicon or silico-manganese intermediate products or SILICOCHROMIUM) Si-Ba calcium and lime make flux production of ferroalloys. Therefore, the carbon content of the product obtained is low; for the production of high melting point, low carbon alloy or pure metal, metal thermal method should be used, the metal is chemically reduced thermal heat generated by the reaction to heat the alloy and slag, and The reaction was automatic.
