Uses of Ferro Silicon Powder
Ferro silicon powder is produced by crushing ferro silicon into granular form and processing it with grinding equipment. Adding a certain amount of ferro silicon powder to steel can significantly enhance its strength, hardness, and elasticity. Therefore, ferro silicon powder is often used as an alloying agent in the smelting of structural steel, tool steel, spring steel, and transformer-grade silicon steel. Ferro silicon for deoxidation provides an effective deoxidation effect, effectively reducing oxides and impurities in steel, thereby improving its purity.
In casting processes, ferro silicon powder is commonly used as an inoculant and nodularizer, preventing the formation of carbides in iron and promoting the precipitation and nodularization of graphite, thereby improving the properties of cast iron. The powder made from ferro silicon 75 is commonly used as a reducing agent in the production of low carbon ferro alloys in the ferroalloy industry. Due to the high chemical affinity between silicon and oxygen, and the low carbon content in LC FeSi (Low Carbon Ferro Silicon), the powder processed from low carbon ferro silicon is also very suitable for use as a reducing agent.
Ferro silicon powder can be used as a suspension phase in the mineral processing industry, aiding in mineral separation. In the welding rod manufacturing industry, ferro silicon powder can be used as a coating for welding rods, improving welding quality. Additionally, high purity ferro silicon powder can be used in the electrical industry to prepare semiconductor-grade silicon, and in the chemical industry for producing products like silicones.
The requirements for the particle sizes of ferro silicon powder vary according to different application fields and uses. Generally, the particle size specifications of ferro silicon powder can be selected based on demand, with common specifications including 325 mesh, 200 mesh, 160 mesh, 100 mesh, 80 mesh, 60 mesh, 40 mesh, 20 mesh, and 10 mesh. For ferro silicon powder used as a binder or deoxidizer, the particle size is required to be below 100 mesh, with a particle diameter of less than 149 microns. The particle size requirement for ferro silicon used in casting is 10-60 millimeters.
In summary, ferro silicon powder is primarily applied in the steelmaking, casting, mineral processing, chemical, and electrical industries. With industrial development and advancements in production technology, the application fields of ferro silicon powder are gradually expanding, and through purification processes, it is expected to be applied in more areas in the future.
