What is the use of ferrosilicon balls?

Ferrosilicon is mainly an iron alloy composed of silicon and iron. Ferrosilicon is made of coke, steel scrap and silica as raw materials, and is refined in an electric furnace to become ferrosilicon alloy. Ferrosilicon can sometimes also be used as an alloying element. Additives, etc., are used in some low-alloy structural steels, spring steels or bearing steels, etc., and are used as reducing agents in some chemical industries or ferroalloy production. It is precisely because of the wide range of uses of ferrosilicon that people They are made into ferrosilicon balls, so that their particle size can be relatively uniform, the mesh can save a lot of fuel when it is used, the burning time is longer, the speed of melting is accelerated, and the distribution is uniform.

When ferrosilicon balls are used as steelmaking additives, it can achieve rapid deoxidation and adjust iron trace elements in molten steel, which is mainly due to the internal silicon Si and iron C elements, and the corresponding ferrosilicon balls are put into molten steel according to the standard. When the temperature reaches the dissolution standard, the ferrosilicon balls are uniformly dissolved in the molten steel, and the silicon and oxygen in the molten steel react to form silicon dioxide. This element is harmless to the molten steel and makes the oxides in the molten steel float on the surface of the molten steel, which is easy to screen. out, so as to improve the purity of molten steel and improve the quality of molten steel.

The use of ferrosilicon balls in the foundry industry can be used as a good inoculant and graphite modifier. After the silicon element is dissolved in the molten steel, the silicon element can be dissolved in the molten steel, thereby producing a seeding effect and significantly increasing the number of eutectic particles, thereby Improve the quality of cast iron, and the addition of iron element can improve the graphite ability in the casting process, improve the graphite morphology through a-b, significantly reduce the white mouth tendency of cast iron, and improve the flow of molten iron.

Ferrosilicon balls are widely used in some industrial production of pig iron smelting and general casting, and are a good material. Ferrosilicon balls are generally mainly used in the smelting of pig iron from steel slag, which increases the output and speeds up the production speed. , are also used in ordinary casting and other production.
