Abstract
The object of providing a method for conditioning a working roll with which the material properties of a working roll can be set in a process-reliable and uniform manner is achieved by a method in which a roll and at least one pressure tool are rotated relative to each other, in which pressure is applied locally to the roll by means of the at least one pressure tool, comprising at least one pressure element, via the at least one pressure element, and in which a deep rolling process is carried out.
Claims18
A method for structurally conditioning a roll body of a working roll of a roll stand, comprising the following steps,
- rotating said roll body of said working roll relative to at least one pressure tool, wherein said pressure tool comprises at least one pressure element,
- applying a pressure locally to said roll body of said working roll by means of said at least one pressure tool via said at least one pressure element, and
- moving said at least one pressure tool relative to said roll body of said working roll with a feed motion in the axial direction of said roll body of the working roll such that said pressure is applied to at least one surface section of the roll via the at least one pressure element,
- whereby a deep rolling process of said roll body of said working roll is carried out.
