Ferroalloys can be divided according to different classification standards, mainly including the following classification methods:
Classification by main elements: Ferroalloys can be divided into silicon series, manganese series, chromium series, vanadium series, titanium series, tungsten series, molybdenum series and other series. For example, ferrosilicon, ferromanganese, ferrochrome, etc.
Classification by carbon content: Ferroalloys can be divided into high carbon, medium carbon, low carbon, micro carbon, ultra-micro carbon and other varieties. For example, high carbon ferromanganese, medium carbon ferrochrome, micro carbon ferrosilicon, etc.
Classification by production method: Ferroalloys can be produced by blast furnace method, electric furnace method, out-of-furnace method (metal heat method), vacuum solid reduction method, converter method, electrolysis method and other methods. For example, blast furnace ferroalloys, electric furnace ferroalloys, out-of-furnace ferroalloys, etc.
Classification by multi-component ferroalloys: Ferroalloys containing two or more alloying elements, such as silicon-aluminum alloys, silicon-calcium alloys, manganese-silicon-aluminum alloys, silicon-calcium-aluminum alloys, etc.
