What is Calcium silicon alloy？
Calcium silicon alloy is a composite alloy composed of silicon, calcium, iron and other elements. It is an ideal composite deoxidizer and desulfurizer. At present, calcium alloy can replace aluminum for final deoxidation and is used in the production of high-quality steel, special steel and special alloys. Such as rail and mild steel, stainless steel, steel and nickel-based alloys, titanium alloys and other special alloys, Calcium silicon alloys are used as deoxidizers and desulfurizers in the manufacture of high-grade steels. In fact, both calcium and silicon have a strong chemical affinity for oxygen. Calcium, in particular, has a strong chemical affinity not only for oxygen, but also for sulfur and nitrogen. The steel industry accounts for approximately 90% of global CaSi consumption. The alloy is also used for the modification of non-metallic inclusions. Calcium silicon is used to control the shape, size and distribution of oxide and sulfide inclusions and improve the fluidity, workability, ductility and impact properties of steel products.
