Product Introduction
Ferro Silicon 45 is a ferroalloy product with a silicon content of 41%-47%. It is made from high-quality silica, coke, and steel scrap as the main raw materials, and is produced by high-temperature reduction smelting in an electric arc furnace.
Application Fields
Steelmaking Industry: Used for deoxidation in converters, electric furnaces, and refining furnaces to reduce oxygen content in molten steel, decrease inclusions, and improve steel purity and mechanical properties.
Foundry Industry: Used as an inoculant and auxiliary spheroidizing agent to promote graphitization, reduce white cast iron tendency, and improve casting strength and surface quality.
Ferroalloy Production: Used for silicon supplementation and chemical composition adjustment in the production of low-silicon ferroalloys.
Welding Materials Industry: Used in the production of electrode coatings and flux-cored welding wires to improve welding performance and weld quality.
Main Functions
High-Efficiency Deoxidation: Silicon reacts rapidly with oxygen in molten steel, reducing oxygen content and improving steel purity.
Stabilizing Alloy Composition: Effectively controls the chemical composition of molten steel, improving batch stability and process consistency.
Improving Mechanical Properties: Improves the strength, wear resistance, and impact resistance of steel and castings. Reduce production costs. Meet the requirements of low-silicon processes, reduce the amount of high-silicon ferrosilicon used, and lower the overall alloy cost.
