Ca30si60 Silicocalcium Alloy Lump Ferro Alloy Deoxidizer
Silicon Calcium Description
Silicon Calcium 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.

Silicon Calcium Application
Since calcium has a strong affinity with oxygen, sulfur, hydrogen, nitrogen and carbon in liquid steel, silicon calcium alloy is mainly used for deoxidization, degassing and fixation of sulfur in steel fluid.
It is widely used in high quality steel, low carbon steel, stainless steel production and nickel base alloy, titanium alloy and other special alloy production.
-
Silicon Calcium can be obtained in lump or powder form. The most widely used method to integrated steel applications is in the form of cored wire. This is because calcium has a low density and high reactivity in the ladle making it difficult to introduce and retain in the melt. Cored wire eliminates these variables: CaSi powder is blown deep into the steel melt through immersion of steel tubes.
