Introduction to silicon calcium alloy
Si-Ca alloy is a composite alloy composed of element silicon, calcium and iron. It is a kind of ideal composite deoxidizer and desulfurizer.
Both calcium and silicon have a strong affinity for oxygen.Calcium, in particular, has a strong affinity not only with oxygen, but also with sulfur and nitrogen.So the silicon - calcium alloy is a kind of ideal compound deoxidizer and desulfurizer.Silicon alloy not only has strong deoxidization ability, deoxidization product is easy to float up, easy to discharge, but also can improve the properties of steel, improve the plasticity, impact toughness and fluidity of steel.At present, silicon - calcium alloy can replace aluminum for final deoxidization.It is applied to high quality steel.Special steel and special alloy production.For example, rail steel, low carbon steel, stainless steel and nickel-based alloy, titanium based alloy and other special alloys, can be used as deoxidizer silicon calcium alloy.Si-Ca alloy can also be used as a warming agent in converter smelting workshop, as a inoculant in cast iron and as an additive in ductile cast iron production.
