Ferroalloy refers to one or more metallic or non-metallic elements and new silicon barium calcium alloy composed of iron in Tianjin, which is mainly used as an additive steelmaking deoxidizer and alloying elements. For example ferromanganese alloy of manganese and iron in Liaoning new silicon barium, calcium, silicon and ferrosilicon alloy Jilin new silicon iron, calcium, barium, calcium alloy is an alloy consisting of silicon and calcium. Iron and steel industry in the middle of alloy steel with customary (whether or not containing iron), are called iron alloy. Ferroalloys Category: With the development of modern science and technology, ferroalloy varieties is growing. Single iron alloy. Only an alloy containing an alloying element is called a single alloy. Composite alloy. Multiple alloy containing two or more alloying elements. Press ferroalloy carbon content classification. Classification according to production method. Nitride products. Oxide mass.
