The advantage of casting powder

(1) Heat insulation to prevent heat dissipation;

(2) Separate the air to prevent the oxygen in the air from entering the molten steel for secondary oxidation, which will affect the quality of the steel;

(3) Absorbing and dissolving inclusions floating from molten steel to slag interface to purify molten steel;

(4) There is a layer of slag film between the mold wall and the solidified shell, which can reduce the drawing resistance and prevent the bonding between the solidified shell and the copper plate;

(5) The air gap between the shell and the mold is filled to improve the heat transfer of the mold.
