Calcium Silicon Alloy is a binary alloy of silicon and calcium, its principal components are silicon and calcium, but also contain different amounts of iron, aluminum, carbon, sulfur and phosphorus and other metals. Due to the strong affinity between calcium and oxygen, sulfur, hydrogen, nitrogen and carbon in liquid steel, Calcium Silicon Alloy is mainly used for deoxidation, degassing and fixing sulfur in liquid steel, calcium silicon after adding liquid steel produces a strong exothermic effect, calcium becomes calcium vapor in liquid steel, stirring effect on liquid steel, which is conducive to the floating of non-metallic inclusions. After deoxidation, the silicon calcium alloy produces non-metallic inclusions with large particles and easy to float, and also changes the shape and properties of non-metallic inclusions. Therefore, the silicon calcium alloy is used to produce clean steel, high-quality steel with low oxygen and sulfur content, and special steel with extremely low oxygen and sulfur content.
1.Product Overview:
Calcium Silicon Alloy is a binary alloy of silicon and calcium, its principal components are silicon and calcium, but also contain different amounts of iron, aluminum, carbon, sulfur and phosphorus and other metals.
2.Application:
1）Due to the strong affinity between calcium and oxygen, sulfur, hydrogen, nitrogen and carbon in liquid steel, Calcium Silicon Alloy is mainly used for deoxidation, degassing and fixing sulfur in liquid steel, calcium silicon after adding liquid steel produces a strong exothermic effect, calcium becomes calcium vapor in liquid steel, stirring effect on liquid steel, which is conducive to the floating of non-metallic inclusions. After deoxidation, the silicon calcium alloy produces non-metallic inclusions with large particles and easy to float, and also changes the shape and properties of non-metallic inclusions. Therefore, the silicon calcium alloy is used to produce clean steel, high-quality steel with low oxygen and sulfur content, and special steel with extremely low oxygen and sulfur content.
The addition of Calcium Silicon Alloy can eliminate the nodulation of the steel with aluminum as the final deoxidizer in the ladle, and the blockage of the water mouth of the intermediate tank in continuous casting steel and iron making.
2）Casting application:
In the production of cast iron, in addition to deoxidation and purification, Calcium Silicon Alloy also plays a certain inoculation role, which helps the formation of fine-grained or spherical graphite, so that the graphite distribution in gray cast iron is uniform, reducing the tendency of white mouth; And can increase silicon, desulfurization, improve the quality of cast iron, has a very wide range of application prospects.
