1.Since calcium has strong affinity with oxygen, sulfur, hydrogen, nitrogen and carbon in molten steel, silicon-calcium alloy is mainly used for deoxidation, degassing and fixed sulfur of molten steel.
2.Silicon calcium is added to the molten steel to produce a strong exothermic effect. Calcium becomes calcium vapor in the molten steel, which agitates the molten steel and is advantageous for floating non-metallic inclusions.
3.After deoxidation of the silicon-calcium alloy, non-metallic inclusions with large particles and easy to float are produced, and the shape and properties of the non-metallic inclusions are also changed. Therefore, silicon-calcium alloy is used to produce clean steel, high-quality steel with low oxygen and sulfur content, and special performance steel with extremely low oxygen and sulfur content.
4.The addition of silicon-calcium alloy can eliminate the nodulation of steel with aluminum as the final deoxidizer in the ladle, and the problem of blockage of the continuous tank steel | iron tank intermediate tank. In the refining technology of steel, the deoxidation and desulfurization are carried out with silicon calcium powder or core wire to reduce the oxygen and sulfur content in the steel to a very low level; the sulfide form in the steel can also be controlled, and the utilization rate of calcium is also improved.
5. In the production of cast iron, in addition to deoxidation and purification, the silicon-calcium alloy also plays a role in the formation of fine or spherical graphite; it makes the graphite in the gray cast iron evenly distributed, reduces the tendency of white mouth; desulfurization, improve the quality of cast iron.
