Abstract: Improved casting powders and improved casting slags enable production of steels having high aluminum contents of greater than or equal to 1% by weight and, in some cases, high manganese content of greater than or equal to 15% by weight. In some examples, such steels may also or alternatively include greater than or equal to 0.2% by weight titanium. The casting slag may result from a casting powder that comprises CaO and Al2O3 components essentially in the form of prefused calcium aluminate. Methods for casting steel, including methods for continuously casting steel, are also disclosed based on the use of the disclosed casting powders or casting slags.

Abstract: A casting mould for casting steel melt into a continuously drawn strand is provided herein. A surface texture is formed on at least one inner surface of the casting mould facing towards the melt to be cast. The surface texture extends at least over region of the casting mould which, during operation, is wetted with slag floating on the melt that has been poured into the casting mould. The casting mould allows optimum solidification behaviour in the region of the casting mould that is critical in terms of the risk of crack formation. The surface texture is designed as a closed structure with self-contained, randomly distributed indentations.
