The Melting Point Of Ferro Silicon

What is the melting point of ferro silicon?

Generally speaking, the melting point of ferro silicon is between about 1410℃ and 1460℃. Specifically, the melting point of ferro silicon with a silicon content of 30% is about 1410℃, while the melting point of ferro silicon with a silicon content of 75% is about 1460℃. In addition to being affected by factors such as silicon content and carbon content, the melting point of ferro silicon is also related to factors such as pressure and impurity content. When there are a lot of impurities in ferro silicon, its melting point will increase significantly. In addition, the melting point of ferro silicon will also increase under high pressure conditions. The melting points of ferro silicon produced by different manufacturers will also vary.

Ferro silicon is an iron alloy composed of iron and silicon. Ferro silicon is an iron-silicon alloy made by smelting in an electric furnace using coke, steel scraps, and quartz (or silica) as raw materials. Since silicon and oxygen can easily combine to form silicon dioxide, ferro silicon is often used as a deoxidizer in steelmaking. At the same time, since a large amount of heat is released when SiO2 is generated, it is also beneficial to increase the temperature of molten steel while deoxidizing. At the same time, ferro silicon can also be used as an alloying element additive, widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel. Ferro  silicon is often used as a reducing agent in ferroalloy production and chemical industry.

Ferro silicon is an indispensable deoxidizer in the steelmaking industry. In torch steel, ferro silicon is used for precipitation deoxidation and diffusion deoxidation. Brick iron is also used as an alloying agent in steelmaking. Adding a certain amount of silicon to steel can significantly improve the strength, hardness and elasticity of steel, improve the magnetic permeability of steel, and reduce the hysteresis loss of transformer steel.

General steel contains 0.15%-0.35% silicon, structural steel contains 0.40%~1.75% silicon, tool steel contains 0.30%~1.80% silicon, spring steel contains 0.40%~2.80% silicon, stainless acid-resistant steel contains 3.40%~4.00% silicon, heat-resistant steel contains 1.00%~3.00% silicon, and silicon steel contains 2%~3% silicon or more.
