Ferroalloy refining: in addition, the production of pure electric solution alloy additives (such as metal manganese) manganese alloy wholesale and production of carbon-containing vacuum decarbonization ultra low carbon ferrochrome. Also developed several years refining ferrochrome, ferromanganese Methods oxygen blowing method. China around 1940 production of ferrosilicon, ferromanganese with a small electric stove. Ferroalloys Category: States under the requirements of manganese alloy steel manufacturers, the variety of products is divided into several grades. Our ferroalloy standards issued by the state hundreds of brands, varieties in ferroalloy production of silicon, manganese, chromium ferroalloys maximum of three series, more than about 90% of the total output of ferroalloys. Quality manganese alloy | greatly metallurgy (certified) | Silicomanganese greatly by Anyang metallurgical Refractories Limited. Anyang greatly metallurgical Refractories Co., Ltd.
