(1) Used as deoxidizer and alloying agents in the steel industry. In order to obtain qualified chemical composition and guarantee the quality of steel, in the last stage of the steel must be deoxi- dized. The chemical affinity between silicon and oxygen is very large,Thus ferrosilicon is strong deoxi- dizer used in sedimentation and diffusion deoxidation of steel-making. Add a certain amount of silicon in the steel, can significantly improve the strength, hardness and elasticity of steel.
(2) Used as a nucleating agent and spheroidizing agent in the iron industry. Cast iron is a kind of important modern industrial metal materials，It is much cheaper than steel, easily to melt refining, with excellent casting performance and seismic capacity is much better than steel. Especially the nodular cast iron,Its mechanical properties at or near the mechanical properties of steel. Add a certain amount of silicon in cast iron can prevent iron in formation, promote the precipitation of graphite and carbide spheroidizing. Thus in nodular iron production, ferrosilicon is a kind of important inoculants ( Help separate out graphite)and spheroidizing agent.
Properties and advantages of ferrosilicon
1. High purity
The silicon content of high-purity ferrosilicon is very high, usually between 70-75%, so it has a very high purity. This high purity makes high-purity ferrosilicon very important in the fields of iron and steel smelting and casting, because it can provide high-quality silicon element, thereby improving the quality of steel and castings.
2. Good stability
The chemical properties of high-purity ferrosilicon are very stable, and it is not easy to react with other elements. This stability makes high-purity ferrosilicon very popular in fields such as iron and steel smelting and casting, because it can ensure the stable quality of steel and castings and avoid quality problems.
3. Good processing performance
High-purity ferrosilicon has very good processing properties and can be processed by smelting, casting and other methods. This processability makes high-purity ferrosilicon very practical in fields such as iron and steel smelting and foundry, because it can be easily processed into castings and steel products of various shapes and sizes.
4. Good high temperature resistance
High-purity ferrosilicon has very good high temperature resistance and can maintain stability in high temperature environments. This high temperature resistance makes
High-purity ferrosilicon is very practical in fields such as iron and steel smelting and casting, because it can maintain stability in high temperature environments and avoid
Avoid quality problems.
