Contact SupplierThe active element in CaSi is calcium. For aluminum-silicon-killed steels, Calcium treatment by CaSi is normally cheaper than by pure Calcium products. For the molten steel, calcium treatment is a must.
Calcium is used to transform alumina into low melting point calcium-aluminates, avoiding nozzle clogging as well as to control the shape of oxide and sulfide inclusions. During the course of deoxidation and inclusion transformation, efficient calcium treatment plays a very critical role.
With advantages as below:
Eliminate alumina nozzle clogging, spheroidize oxide and sulphide inclusions which increases the tranverse toughness and strength of steel. Improve steel purity.
