Ferroalloys: As deoxidizer manganese alloy steel ball factory, the most widely used is silico-manganese, ferromanganese and ferrosilicon. Strong deoxidizer as ferric, silicon calcium, silicon and zirconium. Commonly used as an alloy additive varieties: ferromanganese, ferrochrome, ferrosilicon, iron tungsten, molybdenum iron, vanadium iron, titanium-iron, nickel-iron, niobium (tantalum) iron, rare earth alloy, boron, iron, phosphorus and iron. The main method of ferroalloy production: classification by heat source. Heating method. Heat electrothermal smelting process is mainly buying power manganese alloy ball, carbonaceous reducing agent oxide ore manganese alloy ball price, the use of continuous operation in the reduction process and electric furnace. Silicon thermal power. Heat silicon thermal power smelting process is mainly electricity, heat the remaining time for the release of silicon oxide, silicon (ferrosilicon, silicon manganese alloys and intermediate products of silicon-chromium alloy) as a reducing agent in the oxide ore. Production is carried out intermittent operations in the refining electric furnace.
