Definitions
- the invention relates to a device for applying lubricants to the circumferential surface of rolls in roll stands for rolling strips, in particular multi-roll stands with support and work rolls, in which the lubricant in each case covers a region of the circumferential surface of the work roll acting on the rolled strip between the upper one or lower belt surface and possibly a scraper positioned against the circumferential surface
- Devices of this type are used, with the aid of the lubricant applied to the circumferential surface of the rolls, to determine the size of the friction d. Between the work roll resting on the rolled strip and the strip surface. H. reduce the coefficient of friction.
- the lubricant applied to the surface of the strip enables reductions in rolling force, improvements in the surface of the strip and increases in the service life of the rollers.
- the lubricant is spray nozzles such.
- B. flat jet nozzles are applied to the peripheral surfaces of the support roller and are transferred from this to the peripheral surface of the work roll. The transfer leads to a thin lubricant distributed uniformly over the peripheral surface of the work roller, which is correspondingly evenly transferred from it to the surface of the roll belt.
- the application of lubricant is effected via application rollers that can be pressed against the peripheral surface of the work roll, the circumference of which is acted upon by the circumference of a transfer roller mounted in a parallel axis, on the peripheral surface of which the lubricant is applied by spraying, centrifugal or immersion transfer devices these devices effecting the application of the lubricant to the peripheral surface of the transfer roller can be set so that only predetermined width regions of the peripheral surface are acted upon by the lubricant.
- further intermediate transfer rollers arranged between the transfer roller and the application roller can also be provided.
- the application roller and, if applicable, the transfer roller and the intermediate transfer rollers can be covered with an elastic, liquid or pasty material-absorbing material.
- a further possibility of applying and transferring the lubricant can be brought about by means of an endless belt comprising material which absorbs liquid or pasty substances and has two parallel-axially mounted guide rollers, to which spraying, centrifuging or dipping devices for applying lubricant are assigned.
- This endless belt can be assigned a pressure roller pair which acts on the outer and inner surfaces in a pressure-adjustable manner.
- a further possibility for the targeted distribution of the lubricating liquid is to arrange displaceable cover plates arranged parallel to the axis of rotation between the spray nozzles and the transfer roller or to provide wipers which can be placed on the peripheral surface of the transfer roller and are difficult to move parallel to the axis of rotation thereof.
- the application roller or these and the transfer rollers together with the intermediate transfer rollers and the spraying, spinning or immersion transfer device can be arranged on a carrier which can be moved transversely parallel to the axis of rotation of the work roller is arranged.
- Applicator roller, intermediate transfer roller, transfer roller and spray spinner or immersion transfer device can also be arranged as a group pair with an assigned carrier from positions in the area at the two ends of the work roller above the respective longitudinal edges of the rolled strip and displaceable relative to one another in the region of the longitudinal center of the rolled strip and back again ,
- Such carriers can advantageously be designed as independent, possibly interchangeable cassettes which can be connected to the roll stand and can be moved in and out of the working position.
- a further possibility for advantageously influencing the process of applying the lubricant to the circumferential surface of the work roll is that the carriers or the axes of the application rolls are moved in an oscillating manner parallel to their axes of rotation.
- Another possibility for the targeted distribution of the lubricant on the application surface of the work roll can be achieved in that the application roll and possibly the transfer roll and the intermediate transfer roll have different axis lengths.
- a very uniform, possibly locally limited distribution of the lubricant on the circumferential surface of the work roll and thus a homogeneous distribution of the coefficient of friction can be achieved.
- the lubricant can also be dosed more precisely and therefore leads to a considerably lower consumption of it.
- the intermediate transfer rollers between the transfer roller and applicator roller can intensify this effect.
- the cladding of the rollers, in particular the applicator roller, with an elastic material that absorbs liquids or pasty substances leads, for example, when pressed against the peripheral surface of the work roller. B. to the fact that a water film present on this peripheral surface is pressed through and thus the lubricant can be safely applied to the peripheral surface.
- any irregularities caused by the rolling operation on the surface of the work roll can be bridged and thus compensated for.
- the circumferential widths of the adjust the layers of lubricant applied to the circumferential surface of the work roll and also adjust their thicknesses according to requirements.
- the arrangement of the application roller and the transfer rollers on a carrier which can be displaced transversely to the axis of rotation of the work roller not only improves the distribution of the lubricant on the peripheral surface of the work roller; it can also be used for edge lubrication of the rolled strip in order to improve the edge wear and the profile of the rolled strip.
- Figure 1 is a view of a radial section through the rollers of a multi-roll stand with two different embodiments of the device in a schematic representation
- Figure 2 is a partial view of Fig. 1 with another embodiment of the device on an enlarged scale
- Figure 3 is a top view of another different form of training
- FIG. 5 shows a further embodiment of the device in a schematic representation.
- the multi-roll stand (not shown in more detail) has two support rolls SW1 and SW2, each of which is assigned a work roll AW1 or AW2.
- the two work rolls AW1 and AW2 are friction-driven by the support rolls SW1 and SW2 in the direction of the arrows and act on the rolled strip WB moved in the rolling direction WR; their peripheral surfaces are acted upon by cooling or anti-peeling devices KE.
- the peripheral surface of the work roll AW1 facing away from the rolling direction WR is acted upon by an application roll ATW, which is followed by an intermediate transfer roll ZÜW and a transfer roll ÜW. These rollers are in frictional connection with one another and the transfer roller ÜW dips with its circumference into an immersion trough TW which contains the lubricant.
- a spray device for the lubricant can also replace the dip pan TW.
- the peripheral surface of the work roller AW1 acting wipers AS are arranged above and below the application roller ATW with the intermediate transfer roller ZÜW, the transfer roller ÜW and the immersion trough TW.
- Another scraper ASÜ which is displaceable parallel to the axis of rotation of the work roll AW1 in a manner not shown, lies on the circumference of the transfer roll ÜW.
- the circumferential surface of the other work roll AW2, below the roll belt WB, is acted upon by an endless belt EB, which consists of an elastic, lubricant-absorbing material and comprises a guide roller pair UR, which is driven in a manner not shown.
- the surfaces of this endless belt EB facing upwards and downwards are sprayed Blasting nozzles SD acted on with lubricant, and the upper run of the belt passes through the pinch gap of a pinch roller pair QR.
- wipers AS acting on the peripheral surface of the work roll AW2 are also arranged.
- the arrangement of the application roller ATW, the intermediate transfer roller ZÜW and the transfer roller ÜW according to FIG. 2 corresponds to the drawing shown and explained in FIG. 1 with the proviso that the transfer roller ÜW is assigned a spray nozzle SPD here, in the spray jet of which, parallel to the axis of rotation the transfer roller ÜW slidable disk diaphragm SB is arranged, with the help of which the application field for the lubricant on the part of the peripheral surface of the transfer roller ÜW facing the spray nozzle SPD can be determined and, if necessary, changed.
- This can also be achieved with the wiper ASÜ, which can be placed on the circumferential surface of the transfer roller ÜW, and the thickness of the lubricant can also be regulated.
- applicator roller ATW, intermediate transfer roller ZÜW, transfer roller ÜW and spray nozzle SPD are each arranged together on a carrier, not shown, which can be moved in the direction of the double arrow PF parallel to the axis of rotation x-x of the working roller AW.
- the supports with the rollers and the respective spray nozzle can be moved towards and away from one another from the positions shown above the respective edges WBR of the rolled strip WB parallel to the axis of rotation xx of the work roller AW, and also allow, in particular, the areas of the edges to apply lubricant to other areas of the rolled strip.
- the rollers are driven oscillating in the direction of their axis of rotation. This can be done for one or more rolls. Coordinated lengths of the rollers ÜW, ZÜW and ATW favor the even distribution of the lubricant to be applied.
- a brush roller BW is arranged above this roller and its immersion tank TW so as to be drivable, the elastic brush elements BE of which fling the lubricant from the surface of the transfer roller ÜW onto the surface of the intermediate transfer roller ZÜW. From this, the lubricant is transferred to the application roller ATW, as in the embodiment according to FIG. 1, and is pressed by the latter onto the surface of the work roller AW. Between the brush roller BW and the intermediate transfer roller ZÜW, as in the embodiment according to FIG.
- a displaceable disc diaphragm SB is arranged, with the aid of which lubricant is applied to the areas of action on the surface of the intermediate transfer roller ZÜW and, via these, the areas of exposure to the surface of the application roller ATW, depending on the width, for example can be applied to the edge lubrication of the strip rolling belt WB.
