What are the factors affecting the absorption of inclusions in molten steel by casting powder?
The submerged nozzle injection in the mold causes the molten steel to move convection, and the inclusions floating on the steel slag interface of the mold may be involved in the solidification shell due to the fluctuation of the liquid level of the mold, resulting in bad subcutaneous inclusions or slag inclusion on the surface and affecting the surface quality.

How does the casting powder lubricate in CCM?
In the process of casting, the mould vibrates up and down, and the casting billet moves downward, causing friction between the surface of the solidified shell and the copper wall, making the billet shell and the copper wall bond, increasing the resistance of the billet drawing, leading to the crack of the billet shell in the light case, and cracking of the billet shell in the serious case.
