  • Method of improving the state of the surface of a roll
    Patent number: 4628179
    Abstract: A method for treating the surface of a roll, e.g. for a rolling mill, by focusing a substantially continuous concentrated corpuscular beam, e.g. a laser beam or an electron beam, on the roll surface, guiding the beam to impinge on the roll surface in a helical path, and regulating the concentration of the beam, the relative speed of rotation of the roll, and the translation speed of the beam so that the ratio of the pitch of the helical path and the width of the path of the beam on the roll surface is less than 1.
