Product Description:

First of all, we should understand the main theoretical knowledge of ferrosilicon. Ferrosilicon is a



kind of metallurgical material rich in silicon elements, which is often used in casting and steelmaking. It is a good deoxidizer in steelmaking and a good accelerator in casting. Ferrosilicon can be divided into different grades according to its silicon content, among which ferrosilicon 75 is a frequently used ferrosilicon product, which is not only used in China, but also exported widely. The grade of ferrosilicon used for different steelmaking and casting products is also different.

The steel-making is an old smelting technique, in the steel-making, the ferroalloy material is heated and melted by an electric furnace to form a steel liquid, and a large amount of oxygen is present in the steel liquid, and the oxygen can form an oxide with the impurities in the steel to greatly reduce the quality of the finished steel product, so that the deoxidation of the molten steel is necessary, The ferrosilicon is the effect of deoxidization, and the rich silicon element in the ferrosilicon can be used as a good deoxidization effect with the oxygen generated in the steel liquid. In the general steel-making steel liquid, the silicon element is required to be in the range of 0.15-0.35%, the silicon-containing 0.40-1.75% in the structural steel, the silicon-containing 0.30-1.80% in the tool steel, and the bullet The content of silicon in spring steel is 0.40% and 2.80%, in stainless acid steel is 3.40% and 4.00, in heat resistant steel is 1.00% and 3.00, in silicon steel is 2% or higher.

Foundry is a new smelting technology after steelmaking. Compared with the low cost and low product quality of steelmaking, ferrosilicon can play a good promoting role in casting and improve the distribution of graphite. At the same time, it can promote the formation of graphite nucleation and greatly shorten the process of graphite nucleation. The addition of ferrosilicon into cast iron can be used as inoculant for ductile iron, and can prevent the formation of carbides, promote the precipitation and spheroidization of graphite, and improve the properties of cast iron.

Through the above explanation, we can see that the steel-making and foundry use ferrosilicon oil is very different, only in steelmaking and casting "the right remedy" can be better production of higher quality products.
