the Description of silicon calcium
Calcium silicate alloy is made of elemental silicon, calcium and iron composite alloy, is a more ideal compound oxygen absorber,desulfurizer. It is widely used in steel, low carbon steel, stainless steel and other steel grades and nickel-based alloys, titanium-based alloysand other special alloys in the production; It is also suitable as a warming agent for converter steelmaking workshop; It can also be used as an inoculant for cast iron andnodular cast ironadditives in production. From about 1907, the electro-silicon-thermal method was used to produce silicon-calcium alloys.
the application of silicon calcium
Both calcium and silicon have a strong affinity for oxygen. Calcium, in particular, has a strong affinity not only for oxygen, but also for sulfur and nitrogen. Therefore, calcium silicate alloy is an ideal composite glue oxygen agent and desulfurizer.Silicon alloysNot only is the deoxidation capacity strong, the deoxidation products are easy to float and discharged, but also can improve the properties of the steel, and improve the plasticity, impact toughness and fluidity of the steel. At present, silicon-calcium alloys can replace aluminum for final deoxidation. is applied to steel. Special steels and special alloys are being produced. For exampleRail steel, low carbon steel, stainless steel and other steel grades and nickel-based alloys, titanium-based alloys and other special alloys, can be used as deoxidizer for silicon-calcium alloys. Calcium silicate alloy is also suitable as a warming agent for converter steel workshop, and can also be used as an inoculant for cast iron and an additive in the production of ductile iron.
