摘要： A rolling mill is rotated while microscopic dents with peripheral ridges are formed by an intermittent laser beam in the presence of a gas jet directed at the beam impact zone. The output and the angle of incidence of the gas jet are controlled and microscopic dents are formed with a ridge on only part of their periphery. Steel sheet cold-rolled by means of such a roll has uniformly distributed hollows, each hollow partially surrounding an elevation.

摘要： A process for surface treatment of a rolling mill roll coated with a coating of metal wherein the coated roll is surface heated, e.g. by a continuous laser beam in a helical path to melt the coating and a thin superficial layer of the roll thereby forming an uninterrupted molten alloy layer comprising at least a part of the coating and of the superficial layer of the roll, cooling the alloy layer, and marking the roller by an intermittent laser beam, e.g. following the same helical path with a given delay to produce local fusion of the alloy layer and of the roll surface beneath the alloy layer and form micro-craters having bases and rims integrated, after solidification, with the alloy layer.
