Ferrosilicon

Ferrosilicon is an iron alloy composed of iron and silicon. Silicon iron is a silicon alloy made of coke, steel dandruff, quartz (or silicon) as raw materials. Because silicon and oxygen are easy to synthesize silicon, silicon iron is often used as a deciduous agent when steelmaking. At the same time, it is also beneficial to improving the temperature of the steel water at the same time as the deoxidation. At the same time, Silicon Iron can also be used as alloy elements. It is widely used in low alloy structure steel, spring steel, bearings steel, heat -resistant steel and electrical silicon steel. Silicon iron is often used as a reducing agent in the iron alloy and chemical industry.

Zhenan supplies FeSi75,FeSi72,FeSi65,FeSi45,and we can provide standard lumps, granules, powder and other processing granularity according to customer requirements.

(1) In the steelmaking industry, it is used as an oxygen and alloy agent. In order to obtain the quality of steel and guarantee steel that qualify for chemical composition, deoxidation must be performed during the steelmaking stage. The chemical affinity between silicon and oxygen is very large. Essence Add a certain amount of silicon in steel, which can significantly increase the strength, hardness and elasticity of the steel, so it is When SiO.40-2.8%) and transformers are used as alloy agents for silicon steel (including silicon 2.81-4.8%). At the same time, improving the form of miscellaneous objects and reducing the content of gas elements in the steel liquid is an effective new technique of improving steel quality, reducing costs, and saving iron. It is particularly suitable for the sealing of the water -casting steel water deoxidation requirements. Practice has proved that the silicon iron not only meets the steelmaking deoxidation requirements, but also has the advantages of desulfurization performance, large proportion, and strong penetration.

(2) In the cast iron industry, it is used as a breeding agent and a ballized agent. Cast iron is an important metal material in modern industries. It is cheaper than steel, easy to melt and smelting, and has excellent casting performance and much better seismic ability than steel. Especially for the mechanical properties of the mechanical performance of the ball and cast iron, the mechanical properties of the mechanical properties are approaching steel. Adding a certain amount of silicon iron to the cast iron can prevent the formation of carbides in the iron and promote the precipitation and ballization of graphite. Therefore, in the ball cast iron, silicon iron is an important breeding agent (help analyzes graphite) and ballized agents.

(3) The iron alloy is used as a reducing agent. Not only is the chemical affinity between silicon and oxygen, but the carbon content of high silicon iron is very low. Therefore, high silicon iron (or silicon alloy) is a commonly used reducing agent when the iron alloy industry low -carbon iron alloys.

(4) 75#Silicon iron is often used in the high temperature smelting process of metal magnesium in the magnesium of magnesium in Pishe. Metal magnesium plays a great role.
