Deoxidizer. During the steelmaking process, oxygen is removed from the molten steel, and some ferroalloys can also remove other impurities such as sulfur and nitrogen from the steel

Alloy additive. According to the composition requirements of the steel grade, alloy elements are added to the steel to improve its properties

Fertility agent. Add iron water before casting cast iron to improve the crystalline structure of the casting

Reducing agent, used for the production of other ferroalloys and non-ferrous metals by metal thermal reduction method; Alloy additives for non-ferrous alloys; It is also used in small quantities in the chemical industry and other industries

Steel, all steel is a type of ferroalloy, which also makes ferroalloys widely used and in large quantities In high school textbooks, certain high carbon iron and all alloys containing iron are also referred to as ferroalloys
