The use of silicon calcium alloy
What is silicon calcium alloy
silicon calcium alloy is a compound alloy composed of silicon, calcium and iron, which is an ideal compound deoxidizer and desulfurizer. It is widely used in the production of high quality steel, low carbon steel, stainless steel, nickel base alloy, titanium base alloy and other special alloys; And suitable for the bof steel training workshop used as heating agent; It can also be used as inoculant of cast iron and additive of nodular cast iron production. silicon calcium alloy was produced by electrosilica-thermal process from about 1907.
The use of silicon calcium alloy
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. So silicon calcium alloy is an ideal compound gelling agent and desulfurizer. Silicon alloy not only has strong deoxidation ability, deoxidation products are easy to float, easy to discharge, but also can improve the performance of steel, improve the plasticity, impact toughness and fluidity of steel. At present silicon calcium alloy can replace aluminum for final deoxidation. It is applied to high quality steel. Special steel and special alloy production. For example, steel such as rail steel, low carbon steel, stainless steel and special alloys such as nickel base alloy, titanium base alloy can be used as deoxidizer. silicon calcium alloy can also be used as heating agent in converter training workshop and as inoculant in cast iron and additive in ductile iron production.
