<p>A heat-treated cladding (44) on the working surfaces of continuous caster rolls (40) reduces sensitization zones. The thermal treatment applied conditions the working surface (44) of the roll substantially uniformly at all positions around the perimeter of the roll (40), thereby disolving carbide formations into an 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.</p> |
