1. Silicon calcium alloy is a new type of deoxidizer used in steelmaking production. It can improve inclusion content and gas element content in steel, reduce costs, and save aluminum. Effective new technology can replace ordinary alloys and pure aluminum for steelmaking. The final deoxidation of the process is especially suitable for the deoxidation requirements of continuous casting molten steel. Practice has proved that it not only meets the deoxidation requirements but also has desulfurization performance. 2. As a deoxidizer for steelmaking, this product can save 15-25% in the final deoxidation of molten steel in converter steelmaking or electric furnace steelmaking, and the total amount of oxide inclusions is reduced by an average of 29%. Improve the morphology of non-metallic inclusions in steel, finer than grain, and increase the strength value of steel by 6.14%. The content and recovery rate of acid-soluble aluminum in the steel are increased, which can effectively improve the quality of the steel and the mechanical properties of the steel. Silicon calcium alloy is a composite alloy composed of elements silicon, calcium and iron, and 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 steel grades and special alloys such as nickel-based alloys and titanium-based alloys; it is also suitable as a warming agent for converter steel refining workshops; it can also be used as an inoculant for cast iron. and additives in the production of ductile iron. Since about 1907, silicon-calcium alloys have been produced by the electrosilicothermic method. use: Both calcium and silicon have a strong affinity for oxygen. Calcium, in particular, 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 colloidal oxygen agent and desulfurizer. Silicon alloy not only has strong deoxidation ability, and the deoxidized products are easy to float and discharge, but also can improve the performance of steel, and improve the plasticity, impact toughness and fluidity of steel. At present, silicon-calcium alloys can replace aluminum for final deoxidation. Applied to high-quality steel. Special steel and special alloy production. 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 all use silicon-calcium alloys as deoxidizers. Silicon-calcium alloy is also suitable as a warming agent for converter steel refining workshop. Silicon-calcium alloy can also be used as an inoculant for cast iron and an additive in the production of ductile iron.
