Cored wire is a kind of composite material, which is made of strip steel wrapped with alloy powder. According to the different alloy powder, cored wire can be divided into many types. Here are some common cored wire materials:
Si-Ca cored wire: The cored wire is made of alloy powder composed of silicon, calcium, etc. It is mainly used for deoxidation, desulphurization and alloying of molten steel.
Silicon-manganese-calcium wire: cored wire made of alloy powder composed of silicon, manganese, calcium and other elements, which has the functions of deoxidation, desulphurization, alloying and grain refinement.
Silicon-calcium-barium wire: cored wire made of alloy powder composed of silicon, calcium, barium and other elements, mainly used for deoxidation, desulfurization and alloying of molten steel, which can improve the mechanical properties and corrosion resistance of steel.
Barium-aluminum wire: cored wire made of alloy powder composed of barium, aluminum and other elements, mainly used for deoxidation of molten steel and grain refinement.
Aluminum-calcium wire: Cored wire made of alloy powder composed of aluminum, calcium and other elements, mainly used for deoxidation, degassing and alloying of molten steel.
Calcium-iron wire: A cored wire made of alloy powder composed of calcium, iron and other elements, mainly used for deoxidation and alloying of molten steel.
Pure calcium wire: cored wire made of pure calcium powder, mainly used for deoxidation and alloying of molten steel, which can improve the purity and mechanical properties of steel.
In addition, there are some other special material cored wire, such as rare earth cored wire, titanium iron cored wire, carbon cored wire, etc., they all have their own characteristics and uses.
It should be noted that the material selection of the cored wire should be determined according to the specific process requirements and steel characteristics to ensure the effect and safety of the cored wire in the molten steel.
