Common ferroalloy products are ferrosilicon, ferrochrome, ferromanganese, calcium silicate alloy, etc. Generally speaking, ferroalloys play an important role in the process of steelmaking, such as deoxidizing, purifying, reducing cost and improving quality.
The production of ferroalloys requires a great consumption of electric energy, and is generally produced by carbon heating using a mineral heat furnace. Some ferroalloys with low carbon content need to be produced by smelting the intermediate alloy first and then by metal heat reduction, etc. For different grades of the same ferroalloy, the higher the alloying element content, the lower the content of carbon, phosphorus and other impurities, the higher the price, and the better its effect on steelmaking.
As the ferroalloys used in steelmaking should be produced according to the requirements of the steel type, so as to reduce the cost of steelmaking by producing ferroalloys of appropriate grades. The subsequent processing of ferroalloy also needs to be classified according to the composition and processed into the shape of a certain particle size for use, the general particle size of ferroalloy is 10 ~ 50mm, in the process of steelmaking can make the steel and ferroalloy composition uniformly fused to play a chemical reaction and reduce the loss in the use of ferroalloys before it is necessary to carry out the baking process, which is mainly for the purpose of reducing the gas carried into the steel water.
