Gray Solid Grade 72 Ferro Silicon

Ferro silicon 72 is mainly composed of silicon and iron with high silicon content, which makes it have unique properties. First of all, ferro silicon 72 has good deoxidation performance, which can effectively remove oxygen from molten steel and improve the quality of steel. In addition, ferro silicon 72 has high thermal stability and chemical stability, and it can maintain stable performance in harsh working environment. As an important alloy material, ferro silicon 72 is widely used in metallurgy, chemical industry, machinery and other industries.

Ferro silicon 72 plays a vital role in metallurgical industry. Firstly, as a deoxidizer, it can effectively remove oxygen from molten steel. Oxygen is a harmful element in steel, which will increase the brittleness and decrease the mechanical properties of steel. Ferro silicon 72 reacts with oxygen in molten steel to generate oxides insoluble in molten steel, so as to remove them from molten steel and improve the quality and performance of steel. In addition, ferro silicon 72 can react with other impurity elements in molten steel such as sulfur and phosphorus to form stable compounds, thus further purifying molten steel. By adding ferro silicon 72, we can significantly improve the purity of steel and improve its processability and corrosion resistance.

Ferro silicon 72 also plays an important role in foundry industry. It can be used as an inoculant to promote the spheroidization of cast iron. Ductile iron has excellent mechanical properties and corrosion resistance and it is widely used in automobile, machinery and other fields. The addition of ferro silicon 72 can significantly improve the spheroidization rate of cast iron and improve its microstructure and properties. At the same time, ferro silicon 72 can refine the grains of cast iron and improve its density and strength. This is helpful to reduce the defects such as shrinkage cavity and air hole, and improve the quality and reliability of castings.
