Definitions

the present invention relates to a method of surface treatment of a rolling mill cylinder. It relates more particularly to a method of marking cold rolling mill rolls which must impart controlled roughness to a steel sheet.
the subject of the present invention is a method making it possible to achieve this objective.
the method of surface treatment of a rolling mill cylinder which is the subject of the present invention, in which the surface of said cylinder is marked by means of an intermittent laser beam, is essentially characterized in that before carrying out said marking, a coating consisting, at least in part, of a metallic substance is applied to said surface.
a metallic coating composed of nickel, chromium, cobalt or an alloy of at least two of these metals is applied to the surface of said cylinder.
a coating is applied to the surface of said cylinder comprising at least one metal and at least one metal oxide.
the metal oxide can, according to the invention, come from a metal different from that which enters into the composition of said coating.
the presence of nickel oxide, associated with nickel causes an increase in the amount of energy of the laser beam absorbed by the surface; this results on the one hand, an increase in the depth of melting and therefore an increased roughness depth, and on the other hand a better alloy of the metal of the cylinder with nickel and a higher hardness of the solidified bead.
a coating or a powder containing at least one hardening component such as a carbide or a nitride and / or at least one, is applied to the surface of said cylinder. component capable of reacting with at least one component of the material of said cylinder to form said curing component.
the said coating is applied by any method known per se, suitable for the coating material used.
a powder can also be deposited by an appropriate method.
the coating applied to the surface of said cylinder advantageously consists of a substance capable of - or containing at least one capable constituent - to ally with the locally molten material of the cylinder and / or to react with at least one of the constituents of this material.
the hardening effect resulting from the aforementioned alloy or reaction is located essentially in the beads which surround the micro-craters, that is to say precisely in the regions which serve to imprint the roughness. in the sheet rolled with this cylinder.
This implementation therefore ensures maximum efficiency of the process of the invention.
the method of the invention can be illustrated, by way of example, by its application to a rolling mill cylinder of steel of conventional composition.
the surface thus coated was then treated, by means of a laser with a power of 1 kW, so as to form a roughness Ra of 4 to 5 ⁇ m.
the craters formed were well separated.
craters were obtained having a bcurrelet composed of an alloy containing a high proportion of f cobalt, and whose height is of the order of 10 to 15 ⁇ m.
the figure represents a section of one of these beads, photographed with a magnification of 2000 times with a scanning electron microscope.
the coating resin is on the right, the bead of highly alloyed metal is in the center and the metal of the cylinder on the left (this one was prepared by etching for the micrographic examination).
