sica inoculant

SiCa inoculant (Calcium silicon alloy): It is a composite alloy composed of elements silicon, calcium and ferro. 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; and is suitable as a warming agent for converter steel-making workshops; it can also be used as an inoculant for cast iron And additives in the production of ductile iron. 

SiCa inoculant grades and chemical composition 

The role of SiCa inoculant: Calcium and silicon have a strong affinity with oxygen. Especially calcium, not only has a strong affinity with oxygen, but also has a strong affinity with sulfur and nitrogen. Therefore, the SiCa inoculant is an ideal composite oxygenation agent and desulfurizer. Silicon alloys not only have strong deoxidizing 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. It is applied to high-quality steel. Special steel and special alloy are in production. For example, steel grades such as rail steel, low carbon steel, stainless steel and special alloys such as nickel-based alloys and titanium-based alloys can all use silicon-calcium alloys as deoxidizers. SiCa inoculant is also suitable as a warming agent for converter steel-making workshops. SiCa inoculant can also be used as an inoculant for cast iron and an additive in the production of ductile iron.
