Definitions
- the invention relates to a roll for a roll stand, comprising a roll axis at least one roller ring arranged thereon, the roller axis being axial is movable.
- the rolling stand for rolling a metal strip can e.g. as Be designed as a duo, quarto or sexto framework.
- the thickness and cross-section are through Roll gap determined.
- the exact contour of the roll gap that occurs under load depends on various influencing factors. These are the wear and tear of the Work rolls, the elastic deformation of the roll system, the roll grinding (Crowning) and the thermal crowning as a result of uneven heating the roller bale between the center of the bale and the edge of the bale. Without the correction the crowning of the work rolls increases with actuators Rolling material throughput is constantly increasing, and due to the changing thermal Bombing increasingly deviates from the target contour, e.g. a Parabola, ab.
- the invention is therefore based on the object of a generic roller create with which the setting of the roll gap during the rolling process simplify and make more precise than the known measures and which reproduces the setting options of the individual roller pairs.
- the actual shape can be set much more precisely because of the multi-part construction and assembly the roller according to the invention already within a single roller offers a variety of ways to change the outer contour of the roller set the desired roll gap. All the more so if after a suggestion the invention not only the roller axis, but also the or Roller rings are axially displaceable.
- Another advantage of the invention Roller is that its outer surface, i.e. the area the largest Wear is subject to an axially parallel or cylindrical shape. At the Regrinding this surface therefore needs no consideration of any Contouring to be taken, like the one-piece, curved contoured Rolling is the case in which when reworking the respective roller pairs opposing surface contour must be taken into account precisely. With one A roller according to the invention having internal curvature, however, is sufficient simple, cylindrical cut.
- roller axis and the inner roller ring or the outer surface of an inner and the inner Surface of an outer roller ring have a curved contour, wherein the roller rings can be made in one or more parts.
- roller rings can be made in one or more parts.
- the mutually facing are curved contoured surfaces interlockingly formed, with can be provided with a thread. It can be taken into account that it is under Circumstances may be necessary between the individual components of the roller To transmit moments beyond the maximum that can be transmitted solely by friction Moment go out.
- a roller 1 shown in FIG. 1 to be used as a work or intermediate roller consists of a roller axis 2 with an inner roller ring arranged thereon 3 and a concentrically surrounding outer roller ring 4.
- Die Surface 5 of the roller axis 2 like the - inner - surface 6 of the inner roller ring 3 a contour curved in the axial direction, the Surface contours of this pair are rotated by 180 ° to each other.
- the outer Roll ring 4 however, has a cylindrical, i.e. uncontoured shape.
- the inner Roller ring 3 axially displaceable; an operating position with the adjustment to the left inner roller ring 3 and roller axis 2 shifted to the right is in FIG. 2 shown.
- FIG. 3 and 4 show examples of the use of the roller 1 as backup rollers for one-piece work rolls 7, 8 at different widths of the rolled strip 9 (Fig. 3) or 10 (Fig. 4).
- the load or Band width of the support width by means of the rollers 1 neither the inner roller rings 3 the roller axes 2 are still axially displaced. In this situation takes place over the entire axial course of the curved contour one touch - corresponding to the Length of the inner roller rings - the curved surfaces 5 and 6 of the roller axis 2 and inner roller ring 3 instead.
- FIG. 3 shows examples of the use of the roller 1 as backup rollers for one-piece work rolls 7, 8 at different widths of the rolled strip 9 (Fig. 3) or 10 (Fig. 4).
- the load or Band width of the support width by means of the rollers 1 neither the inner roller rings 3 the roller axes 2 are still axially displaced. In this situation takes place over the entire axial course of the curved contour one touch - corresponding to the Leng
- FIG. 5 A configuration to possibly between the individual elements of the Roller to transmit such moments that can be transmitted only by friction maximum torque is shown in Figs. 5 and 6, being there the roller axis 102 and the roller ring 103 concentrically surrounding it are positively connected.
- a work or backup roll 100 with on the inner roller ring 103 also arranged cylindrical outer Roller ring 104 is there the axial displaceability with non-cylindrically contoured Surfaces guaranteed by a roller axis thread 12 (see. Fig. 6).
