Calcium Silicon

What is Calcium Silicon?

Calcium silicon, also known as ferro silicon calcium, is an alloy that is composed of calcium, silicon, iron, and some impurities such as aluminum, carbon, sulfur, etc. Calcium silicon is mainly used as a deoxidizing agent. Calcium silicon is mainly in calcium silicon lump, calcium granule, calcium silicon powder, and CaSi cored wire. ZXferroalloy introduces the uses of calcium silicon alloy in different shapes.

The Uses of Calcium Silicon

Calcium has a strong affinity with oxygen, sulfur, hydrogen, nitrogen, and carbon in molten steel, calcium silicon alloy is mainly used for deoxidation, degassing and fixation of sulfur in molten steel. After adding molten steel, a strong exothermic effect is produced, which turns into calcium vapor in the molten steel, which stirs the molten steel and is beneficial to the floating of non-metallic inclusions.

Calcium silicon alloy is deoxidized, non-metallic inclusions with larger particles and easy to float are produced, and the shape and properties of the non-metallic inclusions are also changed. Therefore, calcium silicon alloy is used to produce clean steel, high-quality steel with low oxygen and sulfur content, and oxygen-containing alloys. , special performance steel with extremely low sulfur content.  

Calcium Silicon Granule for Sale

Calcium Silicon Granule Uses

Calcium silicon inoculant is an inoculant that can improve the workability of high-strength gray cast iron and a method for preparing gray cast iron. Calcium silicate inoculant reduces the cross-section sensitivity and whitening tendency of gray cast iron and is conducive to obtaining fine and evenly distributed A-type graphite. , the obtained gray cast iron has higher strength and better machinability.

Calcium Silicon Cored Wire Uses

The main raw material of calcium silicate cored wire is calcium silicon powder, which is used as the core material. The outer sheath is steel skin, which is pressed by a wire crimping machine.

When used in steelmaking, it can purify the form of steel inclusions, improve the castability of molten steel, improve the performance of steel, significantly increase the yield of alloys, reduce alloy consumption, reduce steelmaking costs, and have significant economic benefits.

During the smelting and refining process of molten steel, a large number of oxides or deoxidation products will be generated. If these oxides are not removed, they will have a fatal impact on the inherent quality of the steel.

Therefore, calcium silicon cored wire is fed into the molten steel to utilize the strong reducing property of Ca to interact with the steel. The deoxidation product reduces the metal oxides in the steel to generate calcium oxides, or forms low melting point composite compounds with other oxides that easily float in the steel, that is, the denaturation of Ca oxides, thereby reducing the oxides in the steel and purifying the molten steel. improve the purity of steel. Calcium silicon core wire has the characteristics of easy control, easy storage, low calcium treatment cost and stable calcium treatment effect.
