Beschreibung
Zusammenfassung:	Continuous casting mould includes a substrate layer and a wear resistant layer with the upper part of the boundary between the layers formed as a curved surface having a radius of curvature of 15 to 25 times the thickness of the wear resistant layer. Used for reinforcing mould inner wall of continuous casting mould. Corrosion resistance, heat-resisting fatigue and high temp. proof stress are provided in an upper part of the mould in contact with the molten steel and corrosion resistance and wear resistance are provided in a lower part of the mould in contact with a solidified surface of a casting.
