Production Method Of Ferro Silicon Alloy

     Si-al-FE alloy is a composite strong deoxidation agent, the use of silicon-aluminum alloy in the process of ironmaking, than the use of pure aluminum as a single deoxidation agent, the formation of low melting point products, easy to float to the surface of molten steel, reduce the inclusion of steel, with pure molten steel to improve the quality In addition to being a deoxidation agent, the silicon-aluminum alloy can also be used for the production of spacecraft and automotive components, which can greatly improve the service life of components.Ferro Silicon Alloy
     The main methods of production of Si-al-Fe are as follows: remelting smelting of Si-al-FE alloy is the melting of ferrosilicon, aluminum and steel scraps. According to the pre production of Ferrosilicon aluminum alloy grades and the smelting recovery of silicon and aluminum to calculate the raw material ratio, and then the Ferrosilicon and other raw materials broken into small pieces, weighing mixed, add medium frequency Induction furnace, under the protection of inert gas melting, casting into silicon aluminum alloy ingots.Ferro Silicon Alloy
     Silicon-aluminum alloy is produced by hot-stamping of ferrosilicon and aluminum ingot, and the aluminum ingot is preheated in a molten iron ladle, which is prepared by the silicon-aluminum alloy, and is protected by adding ice crystals and other salts. The Ferrosilicon water will be poured into molten iron ladle to melt aluminum ingot, produce silicon-aluminum alloy, and then cast into silicon-aluminum alloy ingot. The production of Si-al-FE alloy by carbon-thermal method is based on silica, fly ash or bauxite (or other mineral containing $literal), steel chip and so on, coke or petroleum coke, bituminous coal as reducing agent, smelting Si-Al alloy directly in the electric furnace. The key to smelting is to make the furnace reach a higher temperature than the silicon-aluminum iron.Ferro Silicon Alloy
     The furnace temperature is high, the alloy aluminum can be high, the furnace temperature is low, the alloy contains aluminum also low. In order to achieve and maintain the high temperature in the furnace, the lower-level working voltage, larger polar circle power and higher current-voltage ratio are adopted than ferrosilicon, and the non-conductive refractory bricks are used as lining.Ferro Silicon Alloy
