High Carbon Silicon 6515

The chemical composition of high carbon silicon 6515 is Si65%, C15%. It is a new type of steelmaking deoxidizer that improves the physical, mechanical and process properties of steel. Silicon carbon alloy 6515 has a strong ability to remove gas and change non-metallic inclusions, and has the functions of refining and desulfurizing inclusions, spheroidizing and refining grains, improving steelmaking quality and mechanical properties. It ensures low Als in steel, less AL203 inclusions, and can reduce and eliminate large calcium aluminum silicate particle inclusions in steel.

The deoxidizers used in domestic metallurgical steelmaking production are mainly ferromanganese, ferrosilicon, and silicon manganese, and the final deoxidizer is mainly aluminum and aluminum alloys. The traditional deoxidation methods include direct deoxidation with metallic aluminum, deoxidation with aluminum and aluminum alloys, and the deoxidation product AL203 is a microscopic inclusion or ultra-microscopic inclusion, which is not easy to be removed from the molten steel, affecting the quality and mechanical properties of the steel. High carbon silicon 6515 is a new alloy composed of Si and C. Its function is to improve the quality of steel, meet the deoxidation requirements in the metallurgical steelmaking production, ensure that there are few AL203 inclusions in the steel, and improve the grain size and mechanical properties of the steel.
