CORED WIRES - MATERIAL DETAILS
Crushing the additives (deoxidant,desulfurizer,alloys) into certain granulation (in the form of powder), then,using the equipment to fill the powder into the “U” shaped sheath, which is made of high quality cold rolled steel strip, lastly, tightly closing the wire, so a multiple material(cored wire) with certain length will be obtained.Calcium Silicon (CaSi) is a potent deoxidizer and desulfurizer utilized in the production of high grade steels. Calcium Silicon is used to control the shape, size and distribution of oxide and sulfide inclusions improving fluidity, machinability, ductility, and impact properties of the final product.Calcium iron (CaFe) contributes greatly to deoxidation, desulfuration and impurity removing, it also helps increase the collecting rate of rare earth elements and other elements, enable the stability of the composition, reduce the usage amount of valuable mental elements.
