Abstract
A continuous casting mold includes a metallic substrate, an upper portion where the meniscus of molten metal is located during operation, a lower portion having a cross-sectional area smaller than the upper portion, the upper portion and lower portion being joined by a smooth curved surface, a coating of metal dissimilar to the substrate metal, highly resistant to wear, and extending over the curved surface, the curved surface having a radius of curvature at least fifteen to twenty-five times the thickness of the dissimilar metal coating, whereby the dissimilar metal will adhere strongly to the substrate to resist scratching and abrasion to thereby produce a smooth mold piece.
