Ferroalloys: ferroalloys production methods. Basic equipment: Equipment submerged arc furnace is more complex, in addition to attention outside the furnace comprises an electrode holding system, the electrode pressure release device, click on the lifting system, charging system, the iron equipment, protective equipment, electrode cooling system, power supply equipment. The main element is generally a higher melting point alloy steel Deoxidants, or its oxide is difficult to restore steelmaking Deoxidants price, difficult to refining the pure metal, if it is easier to restore together with iron smelting. Used in the iron and steel smelting alloy steel Deoxidants plant, where iron not only harmless, but because the anti-fusible molten steel is more favorable. Therefore, the process of steelmaking deoxidation and alloying, mostly added in the form of ferro-alloys. Ferroalloy generally very brittle and can not be used as a metallic material.
