Metallurgical Product Description

Ferro silicon 65 is made from coke, steel scraps, and quartz (or silica) as raw materials and smelted in an electric furnace. In steelmaking, ferrosilicon is used as a precipitation deoxidizer and diffusion deoxidation and is an indispensable deoxidizer in the steelmaking industry. Ferrosilicon can also be used as an alloying agent in steelmaking.

Applications

First: used as a deoxidizer and alloying agent in the steelmaking industry. To obtain steel with a qualified chemical composition and ensure the quality of steel, deoxidation must be carried out in the later stages of steelmaking. The chemical affinity between silicon and oxygen is very large, so ferrosilicon is a strong deoxidizer for steelmaking for precipitation and diffusion. deoxidation.

Second: used as an inoculant and spheroidizing agent in the cast iron industry. Cast iron is an important metal material in modern industry. It is cheaper than steel, easy to melt and smelt has excellent casting properties, and is much better than steel in earthquake resistance. Adding a certain amount of ferrosilicon to cast iron can prevent the iron from Forming carbides and promote the precipitation and spheroidization of graphite. Therefore, ferrosilicon is an important inoculant and spheroidizing agent in the production of ductile iron.

Third: used as a reducing agent in ferroalloy production. Not only is the chemical affinity between silicon and oxygen very high, but the carbon content of high-silicon ferrosilicon is very low. Therefore, high-silicon ferrosilicon is a commonly used reducing agent in the ferroalloy industry when producing low-carbon ferroalloys.

Fourth: The main use of ferrosilicon natural block is as an alloying agent in steel production. It can improve the hardness, strength, and corrosion resistance of steel, and can also improve the weldability and processability of steel.

Fifth: Use in other aspects. Ground or atomized ferrosilicon powder can be used as a suspended phase in the mineral processing industry.
