Metallurgical Product Description

Ferro silicon 70 is an iron alloy composed of iron and silicon. Ferrosilicon is an iron-silicon alloy made from coke, steel scraps, and quartz (or silica) as raw materials and smelted in an electric furnace. Since silicon and oxygen easily combine to form silica, ferrosilicon is often used as a deoxidizer in steelmaking. At the same time, since sio2 releases a large amount of heat when it is generated, it is also beneficial to increase the temperature of molten steel while deoxidizing. At the same time, ferrosilicon can also be used as an alloying element additive and is widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel, and electrical silicon steel. Ferrosilicon is often used as a reducing agent in ferroalloy production and the chemical industry.

Manufacture And Use

Ferrosilicon 70 is widely used in steelmaking, cast iron, low-carbon

Because silicon and oxygen are easily synthesized into silica, ferrosilicon is often used as a deoxidizer in steelmaking. At the same time, since SiO2 releases a large amount of heat when it is generated, it is also beneficial to increase the temperature of the molten steel while deoxidizing. At the same time, ferrosilicon can also be used as an alloying element additive and is widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel, and electrical silicon steel. Ferrosilicon is commonly used as a reducing agent in the ferroalloy and chemical industries.

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.
