A silicon-calcium alloy is a composite alloy composed of the elements of silicon, calcium, and iron. It is an ideal composite deoxidizer and desulfurizer. It is suitable for use as a heating agent in converter steelmaking shops; It can also be applied as a primer for cast iron and an additive in the production of ductile iron.
Calcium and silicon have a strong affinity for oxygen. In particular, calcium has a strong affinity not only for oxygen, but also for sulfur and nitrogen. Therefore, the silicon-calcium alloy is an ideal composite deoxidizer and desulfurizer.
Silicon-calcium alloy not only has strong deoxidation ability, the deoxidation product is easy to melt and discharge, but also can improve the performance of steel, improve the ductility, toughness and fluidity of steel. At present, a silicon-calcium alloy can replace aluminum for final deoxidation. It is used in steel grades such as rail steel, mild steel, stainless steel, as well as special alloys such as nickel-based alloys and titanium-based alloys. The silicon-calcium alloy can be used as a deoxidizer. The silicon-calcium alloy is also suitable for use as a heating agent in converter steelmaking plants. The silicon-calcium alloy can also be used as a primer for cast iron and an additive in the production of ductile iron.
As the name suggests, silicon-calcium powder is a product of crushing and sieving a silicon-calcium alloy. It has various particle sizes and can be manufactured according to customer requirements.
