The basic principle of ferroalloy production: Ferroalloys breed very complicated, Henan calcium aluminosilicate alloy smelting equipment and smelting method is also more diverse, Tianjin aluminosilicate calcium alloy, how to find out its basic law, in order to more deeply understand it, this going from the basic principles of ferroalloy smelting, the nature of the redox processes go deeper knowledge and understanding, to understand the basic characteristics and laws, which for the ferroalloy production and further discuss its energy conservation is necessary. Iron alloy is an alloy composed of one or two or more fused metallic or non-metallic elements and iron together. For example, silica-alumina-calcium alloy, ferrosilicon is Fe2Si silicon and iron formation, Fe5Si3, FeSi, FeSi2 silicide, etc., which are the main components of ferrosilicon, ferrosilicon and silicon mainly FeSi FeSi2 form, especially FeSi more stable.
