Because of ferroalloy production process taking process is simple Hubei new silicon barium calcium than pure metal system, but also has a lower melting point than the pure metal, body Michigan (referring to body dense small metal such as titanium, boron, etc.) of the advantage of Tianjin new silicon barium calcium, conducive deoxidation and alloying were steelmaking process. Therefore, steel deoxidation and alloying elements and more added to ferroalloy form. Ferroalloy Product Category: General classification method. Classification according to production method, there are blast furnace ferroalloys, including high carbon ferromanganese blast furnace, low-manganese alloys, ferrosilicon low; furnace ferroalloys, including high carbon ferromanganese, high-carbon ferrochrome, ferrosilicon, silicon manganese alloy, silicon-chromium alloy silicon alloy, calcium alloy, phosphorus iron, low carbon and low carbon ferrochrome, low carbon ferromanganese, iron, vanadium refining; extrajudicial furnace (metal calorimetry) Jilin Ferroalloy new silicon barium, calcium, including chromium molybdenum iron, titanium-iron, boron, iron, vanadium iron, zirconium, iron, high vanadium iron, tungsten and iron; ferroalloy vacuum solid state reduction, including Advanced Micro Devices, vacuum carbon ferrochrome nitride ferrochrome, ferromanganese, etc; converter ferroalloy, including the converter carbon ferrochrome, low carbon ferrochrome converter, converter carbon ferromanganese; electrolysis ferroalloys, including electrolytic chromium, EMM and the like. In addition, the compact oxide alloy with fever and other special alloy.
