Silicon Calcium Alloy is a new type of deoxidizer used in steel production. It improves the inclusion content and the content of gas elements in steel, reduces the cost, saves the effective new technology of aluminum, and can replace ordinary alloy and pure aluminum for steelmaking. The final deoxidation of the process is particularly suitable for the deoxidation requirements of continuous casting molten steel. It has been proved that it not only meets the deoxidation requirements but also has desulfurization performance.

As a steelmaking deoxidizer, this product can reduce the final deoxidation of molten steel in converter steelmaking or electric furnace steelmaking, which can save 15-25%, and the total amount of oxide inclusions decreases by an average of 29%. Improve the form of non-metallic inclusions in steel, finer grain, steel strength value increased by 6.14%. The acid-soluble aluminum content and recovery rate in the steel are improved, and the quality of the steel and the mechanical properties of the steel can be effectively improved.

Silicon Calcium Alloy is a composite alloy composed of elemental silicon, calcium and iron. It is an ideal composite deoxidizer and desulfurizer. It is widely used in the production of high-quality steel, low-carbon steel, stainless steel and other special alloys such as nickel-based alloys and titanium-based alloys; it is also suitable as a warming agent for converter steelmaking workshops; it can also be used as an inoculant for cast iron. And additives in the production of ductile iron. Silicon Calcium Alloys were produced by electrothermal heating from about 1907.

Application:

Calcium and silicon have a strong affinity for oxygen. In particular, calcium not only has a strong affinity with oxygen, but also has a strong affinity with sulfur and nitrogen. Therefore, silicon calcium alloy is an ideal composite oxygen agent and desulfurizer. The silicon alloy not only has strong deoxidation ability, but also the deoxidation product is easy to float and is easy to discharge, and can also improve the performance of the steel and improve the plasticity, impact toughness and fluidity of the steel. At present, silicon calcium alloy can replace aluminum for final deoxidation. It is used in high quality steel. Special steel and special alloys are produced. For example, steel grades such as rail steel, low carbon steel, stainless steel, and special alloys such as nickel-based alloys and titanium-based alloys can be made of Silicon Calcium Alloy as a deoxidizer.
