Definitions

  • the invention relates to a device for cooling rolled strips, in particular for laminar strip cooling when rolling aluminum strips.
  • the invention has for its object to make a device of the type mentioned maintenance and user friendly and more variable in terms of its uses.
  • cooling segments closed on the outer sides with a cover have a media gap extending over their entire length and several cooling segments with a media gap which is transition-free from cooling segment to cooling segment can be arranged in a row.
  • Media gap is understood here to be the outlet gap for the liquid cooling medium, for example rolling oil, water, etc.
  • the covers which are advantageously flush, but leave the media gap free in a base body provided with a continuous, at least one supply connection and transition into the media gap, the cooling segment or the base body can end at the end, each cooling segment be easily tested for functionality before installation.
  • the covers which are flush with the sides of the cooling segments but do not adversely affect the media gap, make it possible to string together several cooling segments with a laminar flow that is essentially transition-free at the separation points from cooling segment to cooling segment, i.e. the gaps of the individual cooling segments have no difference and are continuous to form a common media gap educated.
  • the segment design allows the strip cooling to be variably adjusted to the width of the strip to be rolled, because it is only necessary to line up either more or fewer cooling segments.
  • zone deactivation can be implemented very easily, namely by switching off the media supply to the cooling segments in question.
  • the cooling segments In view of the cooling segments to be operated with low pressures (from 0.01 bar) for the cooling medium, seals can be omitted because the mechanical surface quality is sufficient for sealing. Finally, the laminar flow, which can be achieved virtually without transition when the cooling segments are placed next to one another, allows the cooling segments to be easily manufactured. In fact, their dimensions can be such that the distributor bore, which extends over the entire length of the base body, can be manufactured using conventional drilling technology. Maintenance and service are also made easier, as segment-by-segment replacement is possible.
  • the base body has a cutout axially exposing the distributor bore with an oblique guide surface which, in interaction with a slide wedge having a corresponding guide surface and arranged in the cutout, forms the media gap. Due to the guiding surfaces, a long jet of the emerging cooling medium can be achieved, which favors the laminar flow of the medium as well as smooth surfaces of the media gap.
  • the cooling segments can be arranged against the rolled strip from above and / or from below, for physical reasons advantageously from below, the distance from the rolled strip being approximately 50 to 100 mm.
  • the gap width of the media gap on each cooling segment can be set individually, gap widths of 0 to 3 mm being able to be set.
  • an optimized gap geometry and thus a quiet operation of the cooling segments is achieved.
  • the slide wedge can be screwed in - in each case from the ends of the cooling segment - by screwing it in more or less move the set screw, which is designed as a grub screw, for example, and thus adjust the gap.
  • Gauges or feeler gauges can be inserted between the guide surfaces to check the respective gap width.
  • cooling segments be screwed together with a box-like steel structure.
  • the cooling segments which can not only be strung together, but can also be arranged in any number one behind the other, are thus arranged on a support frame which, when a liquid is used as the cooling medium, serves at the same time to collect and return the cooling medium to be used in the circuit.
  • a cooling segment 1 shown in FIG. 1 from its narrow or front side consists essentially of a cross section rectangular base body 2 (cf. FIGS. 4 and 5 in conjunction with FIG. 7) and an adjustable or adjustable slide wedge 3 arranged on the base body 2. This is fixed by means of screws 5 (cf. FIG. 4), which are provided by are used below in through bores 4 of the base body 2. The bores 4 are formed with sufficient radial clearance for actuating movements.
  • the slide wedge 3 is inserted into a cutout 6 (see FIG. 7), which extends over the entire length of the base body 2 of the cooling segment 1; it projects with a flow nose 7 into a distributor bore 8 penetrating the base body 2 in the longitudinal direction (cf. FIGS. 4 and 5).
  • the section 6 of the base body 2 which merges into the distribution bore 8 and exposes it axially, as shown in FIG.
  • the slide wedge 3 which has a corresponding guide surface 10
  • it forms a media gap 11 shown in FIGS. 4 and 5 in the basic setting, which can be varied by adjusting the slide wedge 3, through which the cooling medium emerges and is sprayed against a roller belt (not shown).
  • the cooling medium for example water
  • the connections 12 continue into a steel structure 13, which is only schematically indicated in the figures and is box-shaped and carries the cooling segments 1, and are connected to a coolant supply (not shown).
  • the cooling segments 1 are, on the one hand, from FIG. 5, from above, through the slide wedge 3 and the base body 2, fastening screws 14 and, on the other hand, at the side facing away from the slide wedge 3, only through the base body 2, fastening screws 15 (see FIG. 4) screwed to the steel structure 13.
  • the front or narrow sides of the cooling segment 1 are provided with lids 16 which are inserted flush with the end outer surfaces of the base body 2 in the base body 2 and which extend over the entire length 17 and 18 (see FIG. 6) of the Completely seal the cooling segment 1 or 100 (see FIG. 6) extending distributor bore 8 to the outside.
  • the covers 16 are designed such that they end below the media gap 11 defined by the guide surfaces 9, 10, i.e. do not cover this (see Fig. 1).
  • a cooling segment 1 of great length 17 is thus formed by a cooling segment 100 of shorter length 18 to cool the strip for a correspondingly wider rolled strip, the media gaps 11 go at the separation points between the one and the other cooling segment 1 or 100 (see FIG 2 and 6) without any difference in one another, and in this way a transition-free laminar flow can be maintained.
  • cooling segment 1 Apart from the different length dimensions, there are no differences between the cooling segment 1 and the cooling segment 100 (see FIG. 6), although the shorter length 18 of the cooling segment 100 only requires a supply connection 12 for supplying the cooling medium into the distributor bore 8.
  • the series of cooling segments 1, 100 possible with essentially seamless media gap 11 allows the respective segment width of the belt cooling to be easily adapted to the specific requirements, i.e. in particular to adjust the width of the rolled strip.
  • the slide wedge 3 is adjustably arranged in the base body 2.
  • insert blocks 19 are fastened to the two front ends of the base body and, as shown in FIG. 1, project with grooves 20 associated with them in the slide block 3 with projecting ends.
  • a set screw 21 screwed into the projecting end of the block is accessible to an operator from outside through a bore 22, and according to the play or free space in the groove 20, the slide wedge 3 can be adjusted or removed from its guide surface 10 by turning the set screws 21 closer to the corresponding guide surface 9 of the base body 2, which is synonymous with a variable setting of the Media gap 11 is.
