Common ferroalloy products include silicon iron, chromium iron, manganese iron, silicon calcium alloy, etc. Generally, ferroalloys play an important role in deoxidation, purification, cost reduction, and quality improvement in the steelmaking process.
The production of ferroalloys requires a large amount of electrical energy consumption. Generally, a submerged arc furnace is used to produce them through carbon heating. Some ferroalloy products with lower carbon content need to first smelt the intermediate alloy and then use metal thermal reduction methods to produce them. The same ferroalloy product has different grades, and the higher the alloy element content, the lower the carbon, phosphorus, and other impurities content, and the higher the price. Its steelmaking effect will also be good, As ferroalloys used in steelmaking, appropriate grades of ferroalloy products should be produced according to the requirements of the steel grade, thereby reducing steelmaking costs. During the subsequent processing of ferroalloys, they need to be classified according to their composition and processed into a certain particle size shape for use. Generally, the particle size of ferroalloys is 10-50mm, which can achieve uniform fusion of the composition of molten steel and ferroalloys during the steelmaking process and reduce losses. Before using ferroalloys, they must be baked to reduce gas entrainment into the molten steel.
