Alloy is an alloy of iron and other elements of the composition. In addition to iron alloy of silicon, manganese, chromium and other ferrous three systems Deoxidizer outer steel plant, including some pure metal, silicon composite alloy, inoculant, the ball like alloy. Ferroalloy mainly used as an additive steelmaking deoxidizer and alloying elements. The main method of ferroalloy production: reduction furnace is divided into electric (arc furnace) and two refining furnace. Reduction electric furnace: the furnace and the charge added to the charge electrode plug buried in steelmaking deoxidizer prices depend arc arc thermal resistance and current generated by the charge, conduct science arc smelting reduction operation. Molten metal and slag accumulation in the bottom and through the taphole timing of iron slag, the production process is carried out continuously.
