Silicon-calcium alloy is a composite alloy composed of elements silicon, calcium and iron. It is an ideal composite deoxidizer and desulfurizer. It is widely used in the production of high-quality steel, low-carbon steel, stainless steel and other special alloys such as nickel-based alloys and titanium-based alloys; it is also suitable as a warming agent for converter steelmaking workshops; it can also be used as an inoculant for cast iron and additives in the production of ductile iron.
use
Both calcium and silicon have a strong affinity for oxygen. Calcium, in particular, not only has a strong affinity with oxygen, but also has a strong affinity with sulfur and nitrogen. Therefore, silicon-calcium alloy is an ideal composite adhesive and desulfurization agent. Silicon alloy not only has strong deoxidation ability, and the deoxidized products are easy to float and discharge, but also can improve the performance of steel, and improve the plasticity, impact toughness and fluidity of steel. At present, silicon-calcium alloy can replace aluminum for final deoxidation. Applied to high-quality steel. Production of special steels and special alloys. For example, steel grades such as rail steel, low carbon steel, and stainless steel, and special alloys such as nickel-based alloys and titanium-based alloys, silicon-calcium alloys can be used as deoxidizers. Calcium-silicon alloy is also suitable as a warming agent for steelmaking workshops of converters. Calcium-silicon alloy can also be used as an inoculant for cast iron and an additive in the production of nodular cast iron.
