Silicon Calcium Alloy

Silica calcium alloy is a composite alloy composed of elemental silicon, calcium and iron, which is a kind of ideal compound deoxidizer and desulfurizer. It is widely used in the production of high-quality steel, low carbon steel, stainless steel and other steel and nickel-based alloys, titanium-based alloys and other special alloys; it is also suitable for use as a temperature increaser in converter steel workshop; it can also be used as an inoculant in the production of cast iron and additive in the production of ductile iron.

Both calcium and silicon have a strong affinity for oxygen. Especially calcium, not only with oxygen has a very strong affinity, but also with sulfur and nitrogen have a strong affinity. Therefore, silicon calcium alloy is a more ideal composite glue oxygen agent, desulfurization agent. Silicon alloy not only deoxidizing ability, deoxidizing product is easy to float, easy to discharge, but also can improve the performance of steel, improve the plasticity, impact toughness and mobility of steel. At present, calcium silicon alloy can replace aluminum for final deoxidation. Being applied to high-quality steel. Special steel and special alloy production. For example, rail steel, mild steel, stainless steel and other steel and nickel-based alloys, titanium-based alloys and other special alloys, can be used calcium silicate alloy as a deoxidizer.

Product Description

Calcium silicon alloy is a compound alloy made up of elements silicon, calcium, and iron, is an ideal compound deoxidizer, desulfurization agent.

At present calcium alloy can be used instead of aluminum for final deoxidation, is applied to high-quality steel, special steel and special alloys production. Such as rail and low carbon steel, stainless steel, steel and nickel base alloy, titanium alloy and other special alloy,

Calcium Silicon Alloys are used as deoxidizer and desulfurizer in the manufacturing of high grade steel. Indeed, Calcium and Silicon both have a strong chemical affinity for oxygen. Especially calcium, have a strong chemical affinity not only for oxygen, but also for sulphur and nitrogen. The steel industry accounts for around 90 % of global CaSi consumption.
