Ferro alloys are a category of alloys that are primarily composed of iron, with other elements added in varying quantities to achieve specific properties and characteristics. These alloys are used in a wide range of industrial applications, including steelmaking, casting, and welding. Ferro alloys are typically produced by smelting or melting iron alloyed with other metals in an electric arc furnace. Common ferro alloys include ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, ferrovanadium, ferroboron, ferrophosphorus, and ferrosilicon magnesium. The properties of these alloys can be tailored to meet specific application requirements by adjusting the ratios of the alloying elements.
Huasheng Metal, as one of the most professional refractory metal suppliers in China, know clearly about ferro alloys types. We offer differnt types of ferro alloys for specific applications. If you have any doubts about ferro alloys and not sure about what ferro alloys types to choose, please feel free to contact us.
There are many production methods of ferroalloys, most of ferro alloy plant processes are produced by pyrometallurgy. According to the smelting equipment used, operation method and heat source, it is mainly divided into the following categories:
According to the refractory metal suppliers production equipment, it can be divided into blast furnace method, electric furnace method, out-of-furnace method, converter method and vacuum resistance furnace method.
According to the different heat sources, it is divided into carbothermal method, electrothermal method, electrosilicon thermal method and metal thermal method.
According to the different production and operation process characteristics, it is divided into flux method, solvent-free method, slag-free method, slag-containing method and continuous and batch smelting methods.
Ferromanganese and ferrosilicon are the most widely used deoxidizers in steelmaking. Strong deoxidizers are aluminum (aluminum iron), calcium silicon, silicon zirconium, etc. (see deoxygenation of steel).
The common varieties used as alloy additives are: ferromanganese, ferrochrome, ferrosilicon, ferrotungsten, ferromolybdenum, ferrovanadium, ferrotitanium, nickel-iron, niobium (tantalum) iron, rare earth iron alloy, ferroboron, ferrophosphorus, etc.
Ferroalloys are added into molten iron before casting to improve the crystalline structure of cast iron. In addition, it is also used as a reducing agent for the production of other ferroalloys and non-ferrous metals by metal thermal reduction. Alloy additives for non-ferrous alloys; Small amounts are also used in the chemical industry and other industries.
