CaFe Cored Wire Description
CaFe mixtures are used to treat aluminum-killed steel.
The low density and low boiling point of pure calcium require special addition methods.
Strictly quality control, accept the third party inspection SGS, etc.

Reduced casting machine nozzle clogging caused by aluminum oxide (Al2O3) inclusions produced during previous aluminum deoxidation processes.
Spheroidization of aluminum oxide and complex inclusions improves the transverse properties of the steel: ductility and strength.
Improve the cleanliness of steel.
Calcium has a strong affinity with oxygen and sulfur, and has an auxiliary effect on deoxidation and desulfurization.
First CaO is formed, then oxysulfide is formed, and finally the sulfide CaS is formed.
CaFe wire manufacturers can produce different core-covered wires according to user requirements. Such as calcium silicon core wire, silicon manganese calcium wire, calcium silicon calcium wire, aluminum calcium wire, calcium iron wire, pure calcium wire, etc.
Alloy cored wire is a composite material. Alloy core wire is made by pulverizing various additives (deoxidizer, desulfurizer, modifier, alloy, etc.) added to molten steel or molten iron into a certain particle size, and then packaging it with cold-rolled low-carbon steel strips as a composite material of any length.
