Ferroalloy mainly used as an additive steelmaking deoxidizer and alloying elements. Deoxidizer: removal of molten steel in the steelmaking process oxygen quality silicon calcium compound deoxidizer, but also the removal of certain alloy steel other impurities such as sulfur, nitrogen and the like; an alloy additive: steel composition according to claim alloying elements into the steel to improve the properties of steel; inoculant: Before casting iron into molten iron plus silicon calcium compound deoxidizer, improving the crystal structure of the casting. Ferroalloy production technology trends: the use of advanced production technology. Continuous smelting calcium alloy, one-step metallurgical silicon chromium alloy, heat exchange and production of low-carbon ferromanganese, low carbon ferrochrome and other production processes, shorten the process calcium silicon compound deoxidizer prices, reduce energy consumption and improve productivity , thus reducing consumption and cost of production.
