Definitions
- the invention relates to a device for cooling a roll in a WaIz- scaffold, with at least one, with a cooling medium, in particular water supplied spray bar having spray nozzles for ejecting cooling medium to the surface of the roller and extending in the direction of a spray bar axis , which is arranged parallel to the roll axis.
- a cooling medium in particular water supplied spray bar having spray nozzles for ejecting cooling medium to the surface of the roller and extending in the direction of a spray bar axis , which is arranged parallel to the roll axis.
- EP 0 374 538 A2 discloses a cooling device which is designed to spray water onto the rolls of a rolling mill, for which purpose a cooling beam is used.
- a cooling beam is used.
- the chilled beam is arranged on a support structure, with which it can be moved horizontally and vertically so that the roller can be optimally cooled.
- the present invention is therefore based on the invention to develop a cooling device of the type mentioned so that with a simple and stable construction, which can be realized inexpensively, an optimal adjustment of the cooling beam of the cooling device is possible.
- This is intended in particular to ensure that, after a roll change and the associated changed roll diameter and / or change in the position of the roll, the optimum cooling beam position and orientation can always be set in order to achieve an optimum cooling result.
- the object of this invention is characterized in that the spray bar is arranged directly or indirectly on a lever, wherein the lever is pivotable about a pivot axis parallel to the roll axis and wherein the spray bar axis and the pivot axis are spaced from each other.
- the spray bar can be translationally moved by a pivoting movement of the lever in two spatial directions and thus adjusted relative to the roller to be cooled.
- the lever is preferably connected to an actuating element at a location different from the pivot axis.
- the lever preferably has two legs, wherein the spray bar is attached directly or indirectly to the first leg and wherein the actuating element is attached to the second leg.
- the adjustment options of the spray bar are further increased by the following measures:
- the spray bar can be moved to the lever indirectly via a Be mounted intermediate lever, wherein the intermediate lever is pivotally mounted on the lever about a pivot axis which is arranged parallel to the roll axis.
- a further actuating element can be arranged for pivoting the intermediate lever about its pivot axis.
- the further actuating element is preferably arranged between the second leg and the intermediate lever.
- the spray bar can be firmly connected to the intermediate lever.
- the pivot axis of the intermediate lever is preferably arranged between the spray bar and the point of application of the further actuating element on the intermediate lever.
- the actuating elements are preferably designed for setting defined displacement paths.
- the actuators are designed as hydraulic piston-cylinder systems.
- the same coverage of the spray jets of the individual spray nozzles can always be maintained, so that the same cooling effect can always be achieved, namely with different roll diameters.
- the parameters distance between the nozzle and roller or roller and coverage of the cooling medium jets are always kept constant by a simple and optimal adjustment of the cooling beam at different roll or roller diameters.
- actuators are basically hydraulically, pneumatically or electrically operated actuators, whereby eccentric, cams or joints can be used. It is also possible to use the proposed solution even with parameter changes of the cooling medium in order to influence the cooling effect.
- the same distance of the spray nozzles to the roller and the surface acted upon by the spray nozzle are kept constant.
- the impact pressure and impact point of the cooling medium is kept constant on the roll surface.
- the spray bar can also be pivoted to achieve a vertical change of the impact point and thus a change in the cooling effect.
- a pivoting of the spray bar for selectively changing the coverage of the spray jets is also possible.
- FIG. 1 is a side view of an apparatus for cooling a roll of a rolling stand when using a roll having a first diameter
- FIG. 2 shows the side view of the same device when using a roller with a second, smaller diameter
- FIG. 3 is a perspective, partially sectioned illustration of the device for cooling according to FIG. 1 or FIG. 2, arranged for an upper roll of the roll stand, and an alternatively designed cooling device for a lower roll, FIG.
- Fig. 4 is a perspective view of the cooling device shown in Fig. 3 for the lower roller.
- FIG. 1 an apparatus 1 for cooling a roller 2 of a rolling mill (not shown) outlined.
- An important part of the cooling device is a
- Spray bar 3 which is supplied via a water pipe 15 with water in known way applied via spray nozzles 4 and sprayed onto the surface of the roller 2.
- the spray bar 3 is tubular and has a spray bar axis 5, which is arranged parallel to the roll axis 6.
- the spray bar is not arranged stationary, but movable.
- a lever 7 is provided, which is pivotally mounted about a fixed pivot axis 8.
- the lever 7 has two legs 10 and 11. At the end of the first leg 10, the spray bar 3 is arranged indirectly via an intermediate lever 12.
- On the second leg 11 engages an actuating element 9 in the form of a linear actuator.
- the actuating element 9 is arranged with its other end 16 fixed to the rolling stand.
- the lever 7 is pivoted about the pivot axis 8, so that the end of the first teat ice 10 moves and displaces the spray lugs 3 about the pivot axis 8 in a circular arc. Accordingly, the distance of the spray nozzles 4 is changed to the roll surface. This effect can be used to adjust the spray bar 3 as the roll diameter changes, thus always maintaining the same (optimal) cooling conditions.
- the spray bar 3 is also arranged so that it can be additionally adjusted (in particular rotated about the spray bar axis 5).
- the already mentioned intermediate lever 12 is provided.
- the intermediate lever 12 is used for the indirect arrangement of the spray bar 3 at the end of the first leg 10.
- the intermediate lever 12 is mounted at the end of the first leg 10 of the lever 7, ie it can pivot about the pivot axis 13 relative to the first leg 10.
- the pivoting movement is controlled by a second actuating element 14 which engages with its one end on the intermediate lever 12 and with its other end on the second leg 11 of the lever 7.
- the spray bar 3 can thus be optimally adjusted relative to the roller 2 with respect to its horizontal and vertical position, whereby this movement is superimposed by a rotation of the spray bar 3 about its spray bar axis 5.
- a rolling stand in which an upper roller 2 and a cooperating with this lower roller 2 'are each provided with a cooling device 1 and 1'.
- the two rollers 2, 2 ' are equipped with different cooling devices 1, 1'.
- the device 1 is used, as described in FIGS. 1 and 2.
- the cooling device V also has a spray bar 3 'with spray nozzles 4', but now the spray bar 3 'is fixed directly to a lever 7'.
- the lever T engages the actuating element 9 ', so that the lever 7 'together spray bar 3' on the roller 2 'can be pivoted to or from this.
- the effect of the cooling depends, inter alia, on the cooling medium, its pressure, its temperature, its quantity, the type of nozzle and its arrangement on the cooling beam and, of course, the distance between the nozzle and the roller or roller to be cooled as well as the temperature of the roller.
- another type of nozzle or other overlap may affect the cooling effect across the roll width.
