Ferrosilicon alloy is composed of iron and silicon. Alloy of iron and silicon (in silica, steel, coke as raw material, 1500-1800 degree heat reduction in the silicon melt 75 ferrosilicon liquid iron manufacturers, forming a silicon alloy). Alloy smelting industry is an important species. Silicon and ferrosilicon by impurities, divided into 21 grades. Ferrosilicon alloy is composed of iron and silicon. Ferrosilicon purposes: to add a certain amount of silicon ferrosilicon outlet 75 in steel, can significantly increase the strength of steel, the hardness and elasticity, thus smelting structural steel (silicon 0.40-1.75%), tool steel (including SiO.30 -1.8%), spring steel (containing SiO.40-2.8%) and transformer silicon (silicon 2.81-4.8%), it is also used as an alloying agent to ferrosilicon. Ferrosilicon production of ferrosilicon 75 _75 _ metallurgy greatly greatly by Anyang metallurgical Refractories Limited. Anyang greatly metallurgical Refractories Co., Ltd. (www.aydawei.com) (www.aydwyjgs.com) strong, credible, in Anyang ferroalloy products and other industries and has accumulated a large number of loyal customers.
