Ferro silicon 75 is an important alloy raw material, mainly used in steel smelting and alloy manufacturing. The main components are silicon and iron, and its chemical composition is generally Si 70%-75% and Fe 20%-25%. In addition, it usually contains small amounts of carbon, aluminum, sulfur and other elements.
Use
Steel smelting
Ferro silicon 75 is used as an alloy additive to adjust and improve the composition and properties of steel during the steelmaking process, such as increasing the silicon and carbon content and improving the strength and hardness of steel.
Alloy manufacturing
Ferro silicon 75 is often used in alloy manufacturing, such as stainless steel, special steel, etc., to adjust the composition and properties of the alloy.
Properties and characteristics
Strength and hardness
Due to the addition of silicon in Ferro silicon, the strength and hardness of steel can be significantly improved.
Heat resistance
Ferro silicon 75 has good stability and heat resistance under high temperature conditions, and is suitable for use in high temperature smelting and processing processes.
Deoxidation
The silicon in Ferro silicon 75 can be used as a powerful deoxidizer to help remove oxides from molten steel and improve the quality and surface finish of steel.
Classification by carbon content
Ordinary Ferro silicon: The carbon content is generally higher, usually between 0.5% and 2%. This kind of Ferro silicon is mainly used in steel smelting, which can increase the content of silicon and carbon and improve the strength and hardness of the alloy.
Low carbon Ferro silicon: The carbon content is low, generally between 0.05% and 0.5%. This kind of Ferro silicon is mainly used in the production of stainless steel, special steel and other alloys, and can effectively control the carbon content of the alloy.
Ultra-low carbon Ferro silicon: The carbon content is very low, usually less than 0.05%. This kind of Ferro silicon is used in the smelting of special steel, which can reduce carbon residue and ensure the specific performance requirements of the alloy.
Classification by Aluminum content
Low aluminum Ferro silicon: The aluminum content is low, usually less than 0.5%.
Medium Alumina Ferro silicon: The aluminum content is between 0.5% and 1.0%.
High aluminum Ferro silicon: The aluminum content is relatively high, generally above 1.0%.
Ferro silicon aluminum: Contains high aluminum content, generally above 30%. Ferro silicon is usually used as a deoxidizer, which can effectively remove oxides from molten steel and improve the quality of steel.
Each type of Ferro silicon has its specific uses and scope of application. Different types of Ferro silicon are selected for use according to specific production needs.
