With the development of modern science and technology, various industries have higher and higher requirements on the variety and performance of steel materials, which also puts forward higher requirements for ferroalloys. The variety of ferroalloys is constantly expanding, there are many varieties of ferroalloys, and there are many classification methods.
Generally classified according to the following methods:
①Classified according to the main elements in iron alloys, mainly silicon, manganese, vanadium, chromium, titanium, tungsten, molybdenum and other series iron alloys
② According to the carbon content of ferroalloys, there are high carbon, medium carbon, low carbon, micro carbon, ultra micro carbon and other varieties.
③ Classified according to production methods, there are blast furnace iron alloys, electric furnace iron alloys, out-of-furnace iron alloys, vacuum solid reduction iron alloys, converter iron alloys, electrolytic iron alloys, etc.
④Multi-component iron alloy containing two or more alloy elements, the main varieties are silicon aluminum alloy gold, silicon calcium alloy, silicon calcium aluminum alloy, silicon calcium barium alloy, manganese silicon aluminum alloy, silicon aluminum barium calcium alloy.
