Introduction to Ferrosilicon

Ferrosilicon is a new type of alloy, which is silver gray in color and appears in block, spherical, granular, and powder forms.

Introduction to Silicon Iron 65

Silicon iron 65 has always been one of the metallurgical materials purchased by metallurgical material manufacturers. The price of silicon iron 65 is slightly lower than that of silicon iron 75 72, but the silicon content is much better than that of low silicon iron. The national standard silicon iron content is better, and the effect in the metallurgical process is also more obvious. At the same time, the smelting cost is greatly reduced. Therefore, the national standard silicon iron 65 is very popular among metallurgical manufacturers!

65 silicon iron is mainly an iron alloy composed of iron and silicon. Due to the easy combination of silicon and oxygen to form silica, ferrosilicon is often used as a deoxidizer in steelmaking. The oxidation reaction itself is an exothermic reaction. Can increase the temperature of molten steel. At the same time, ferrosilicon can also be used as an alloying element additive, widely used in low alloy structural steel, spring steel, bearing steel, and electrical silicon steel, etc. Meanwhile, ferrosilicon is commonly used as a reducing agent in ferroalloy production and chemical industry.

Specification and particle size: natural lump, 10-100mm, powder or according to customer's requirement.

Packing: one metric tonne in a big bag or according to customer's requirement

Application of ferrosilicon 65

1. Used as an inoculant and spheroidizer in the cast iron industry. Cast iron is an important metal material in modern industry. It is cheaper than steel, easier to melt and smelt, and has excellent casting performance and better impact resistance than steel. Especially ductile iron, its mechanical properties are comparable or close to steel. Adding a certain amount of ferrosilicon to cast iron can prevent the formation of carbides in iron, promote the precipitation and spheroidization of graphite. Therefore, in the production of ductile iron, silicon iron is an important inoculant (which helps to precipitate graphite) and crystallizer.

2. Used as a deoxidizer and alloying agent in the steelmaking industry. In order to obtain steel with qualified chemical composition and ensure its quality, deoxidation must be carried out during the steelmaking stage. Silicon and oxygen have a strong chemical affinity, so ferrosilicon is a strong deoxidizer for precipitation and diffusion deoxygenation in steelmaking. Adding a certain amount of silicon to steel can significantly improve its strength, hardness, and elasticity. Therefore, in the smelting of structural steel (0.4%~1.75% Si), tool steel (0.3%~1.8% Si), spring steel (0.4%~2.8% Si), and silicon steel for transformers (2.81%~4.8% Si), ferrosilicon is also used as an alloying agent.

3. Other uses. Fine ground or atomized silicon iron powder can be used as a suspended phase in the mineral processing industry. Can be used as a coating for welding rods in the welding rod manufacturing industry. High silicon ferrosilicon is used in the chemical industry to manufacture products such as silicone.

4.Among these uses, the steelmaking, casting, and ferroalloy industries are users of ferrosilicon. They consume approximately 90% of the silicon iron in total. Among various grades of ferrosilicon, 75% ferrosilicon is currently widely used. In the steelmaking industry, 75% of 3-5 kilograms of silicon iron are consumed for every ton of steel produced.
