Metallurgical Product Description

Ferrosilicon 72 is made from quartzite and coke as raw materials and is heated and smelted in an electric furnace through professional processes. Ferrosilicon 72 has a silver-gray appearance with metallic luster and can be processed into natural blocks, standard blocks, granules, and powder according to requirements.

Product Parameters

Product Advantages

Ferrosilicon 72, usually ferrosilicon containing 72% silicon, with intermediate carbon, sulfur, and phosphorus content.

Ferro silicon 72 is divided into metallurgical material grades according to its elements. The silicon content in ferrosilicon 72 is 72%. The higher the silicon content, the higher the price will be. The national standard ferrosilicon 72 has a medium silicon content, so the purchase volume is also high. Very large. Every year, major smelters are constantly looking for ferrosilicon 72 manufacturers with high quality and favorable prices. Therefore, smelters need to see a national standard ferrosilicon 72 supplier that takes both quality and price into account.

Manufacture And Use

Used as a deoxidizer and alloying agent in the steelmaking industry.

Used as an inoculant and spheroidizing agent in the cast iron industry.

The main use of ferrosilicon natural blocks is as an alloying agent in steel production.

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

Applications

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.

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.

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.

The main use of ferrosilicon natural blocks 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.
