Ferroalloy production of ferrosilicon ferrosilicon powder mineral powder composed of iron and silicon, and then after a powdery substance made from mill for steel, iron deoxidizer. Uses: General silicon steel 0.15% -0.35% ferrosilicon powder mineral prices, structural steel, silicon 0.40% ~ 1.75%, 0.30% silicon steel tool ~ 1.80%, 0.40% silicon steel spring ~ 2.80% beneficiation ferrosilicon flour mill, acid-resistant stainless steel, silicon 3.40% ~ 4.00%, 1.00% silicon steel resistant to 3.00% silicon in silicon 2% to 3% or higher. Ferrosilicon powder composed of iron and silicon alloy ferrosilicon powder dressing, and then after a powdery substance made from mill for steel, iron deoxidizer. Ferrosilicon smelting raw materials and requirements: the composition of the ash metallurgical coke there are certain requirements, in particular FeO about 45%, CaO about 27%, SiO2 about 25%, MgO about 1.0%, Al2O3 <0.4%, P2O5 <0.04%. In order to increase the specific resistance of the charge, increase the chemical activity, but also with the use of coal gas.
