Calcium iron clad wire

The metal calcium is mixed and coated with a certain proportion of iron powder. The mixture composed of 25-35% calcium particles and the rest iron powder is the core powder material, which is wrapped with strip steel. It is mainly used as deoxidizer and desulfurizer in steelmaking process;

① The addition of calcium iron wire in the steelmaking process can avoid the formation of long strip sulfide inclusions, so as to improve the anisotropy of steel.

② With the help of the wire feeder, the molten steel is quickly input to dissolve in the depth of the molten steel, reduce the blockage of the nozzle, and play the role of deoxidation, desulfurization and inclusion removal.

③ It can fine tune other components to improve the yield of metals, rare earth and other elements and ensure the stability of components. Reduce the addition of precious elements and reduce the refining cost.
