Iron Silicon Alloy

Product Overview
Iron Silicon Alloy (FeSi75), also known as silicon iron, is a type of ferroalloy primarily composed of coke, scrap steel, and quartz (SiO2). It has a high silicon content, typically around 75%, and plays a crucial role in the steelmaking, casting, and other metallurgical industries, particularly as a deoxidizer and alloying agent. It is an essential additive in the metallurgy industry for improving steel quality and processing efficiency.

Product Features

• High Silicon Content:FeSi75 contains a high proportion of silicon (around 75%), providing excellent deoxidation effects.
• Strong Deoxidizing Action:Effectively removes oxygen from steel, improving the efficiency of steelmaking and enhancing the quality of the product.
• Energy Savings:Silicon iron helps increase temperature during the deoxidation process, which reduces energy consumption.
• Versatile Applications:Can be used as a metal additive for producing various steel grades and cast iron products.
• Improves Cast Iron Performance:When added to cast iron, silicon iron helps promote graphite precipitation and spheroidization, which enhances the mechanical properties of cast iron.

Applications

• Steelmaking Industry:Silicon iron is widely used as a deoxidizer in steelmaking processes to improve the quality of steel and reduce energy consumption.
• Steel and Casting Industries:FeSi75 is used in the production of low-alloy steels, structural steels, spring steels, bearing steels, heat-resistant steels, and electrical silicon steels.
• Cast Iron Production:Used as a spheroidizing agent and alloying agent in the production of cast iron, particularly ductile iron, to improve mechanical properties.
• Low-Carbon Reducing Agent:High-silicon FeSi is used as a low-carbon reducing agent in ferroalloy production.
• Welding Materials:Silicon iron powder is widely used in the manufacture of welding rods, especially for the coating of welding electrodes and in mineral processing industries.
