Laser cladding the flanks of mill roll grooves* [Full subscriber]

Abstract To reduce the costs of maintaining mill roll shells, efforts have been made to extend roll shell life and to maintain the roughness of the tips of roll grooves through a season without the need for roll arcing. Techniques for maintaining the diameter of the roll and the roughness of the groove tips have been previously developed, including tungsten carbide-impregnated hardfacing and picots. These techniques for coating the tips of the grooves have a deficiency in that they do not protect the lower flanks of the grooves. As a result, the lower flanks continue to wear away at an…
