Abstract: A heat-treated cladding on the working surfaces of continuous caster rolls reduces sensitization zones. The thermal treatment applied conditions the working surface of the roll substantially uniformly at all positions around the perimeter of the roll, thereby dissolving carbide formations into a austenite solution and removing carbide formations and chromium depletion sites or sensitized zones associated with the reheat regions occurring during the welding process. The heat treatment process is accomplished without thermally affecting or altering the properties and dimensions of the base roll material, either at a substantial depth beneath the body working surface or on or beneath the roll journal surfaces.

Abstract: A method is available for forming a surface on a continuous casting mold. A surface of a continuous casting mold is formed by explosion cladding to produce a wear resistant surface having high bond strength. The surface may consist of a hot face of a broad or narrow wall of the continuous casting mold or may comprise the edges of the end walls. Deformation of the mold section is prevented by filling the coolant cavities with a filler prior to explosion cladding.
