Definitions

  • the invention relates to a roll stand with support and / or work rolls for rolling sheets or strips, with at least one arranged between chocks of one of the rolls, preferably the upper roll associated rolling beam and adjacent to the rolling beam arranged inlet / outlet guide for a medium , eg Cooling water od. Like., And with sealants to prevent dripping of the medium on the rolling stock.
  • a medium eg Cooling water od.
  • the DE 100 49 032 A1 is a rolling stand with support and / or work rolls for rolling steel sheets or strips .berianen.
  • This mill has between the work roll chocks arranged, the upper roll associated with a rolling bar, which has attached at the lower roll circumference and the roll bar a water scraper, which can be adjusted outwardly by adjusting against the roll surface.
  • the formed with profile cross-section water scraper is guided in a support bar that in the water scraper extending in the extension of the support bar cavity is formed and that of Cavity with a pressure medium can be acted upon. It is provided in one embodiment that the water scraper is elastic and is guided in a slot of the support bar.
  • the support bar is connected to the roll bar and that the support bar is releasably secured to a mounting surface which is parallel to the roll axis.
  • the water scraper is applied to the full length of the media pressure, so that a contact line arise and thereby even a molding roll could be stripped off.
  • the contact pressure could be maintained independently of the fretting wear.
  • a very accurate adjustment of the support strip accounts, moreover, a minimum number of parts is required.
  • the supply of the pressure medium takes place by means of a compressed air connection in a groove on the back of the water scraper, the profile cross section ends at the end with a sealing lip, in the groove, the pressure medium is introduced.
  • the KR 1020040092252 A shows a stripping device with a shielding device for preventing uneven cooling of a strip by splashing.
  • the described arrangement serves to provide a stripping device with a shielding device for preventing uneven cooling of a strip by spray water, which can be attached to the frame of a hot rolling mill of a hot rolling mill, to effectively drip splashed or leaking cooling water onto the surface of the machined water To avoid rolling stock.
  • the scraper means comprises a front and a rear moving part having a plurality of frame parts which are moved forward and backward to the side of the roller on an upper surface of a scraper body, a scraper arm being attached to a front part of the scraper body, and drive pinions are further provided which engage the frame members to move them forward and backward. Furthermore, a pneumatic motor is provided to move the frame parts by the rotation of the drive pinion forward and backward. Otherwise provided an auxiliary panel which is moved back and forth in front of the frame members with a front part of this auxiliary panel closely abutting the roller at an upper part of the scraper arm to mainly seal cooling water from a plurality of nozzles for cooling the roller.
  • a mounting part via which the additional panel is connected to the front part of the frame parts, such that a front part of the additional panel is in linear contact with the roller and elastically tight against this, according to a change in the rolling gap between the rollers , By spring action as a function of the diameter of the roll and the thickness of the rolling stock.
  • the object of the invention is to improve or further develop the known arrangements while retaining the previous advantages in such a way that media such as e.g. Roll cooling water, emulsion, etc. are eliminated before dripping between the inlet / outlet guides and the rollers / roller fittings, the desired arrangement should be as simple as possible and subject to the least possible wear.
  • the sealing means for preventing the dripping of the medium is formed in particular on the rolling stock as at least one arranged between the rolling beam and the inlet / outlet guide sealing strip.
  • the sealing strip is arranged in a receiving groove arranged in the region between the rolling beam and the inlet / outlet guide.
  • the receiving groove is arranged in the rolling beam in a preferred embodiment.
  • the sealing strip is mounted biased in the receiving groove against the rolling beam.
  • the sealing strip thus fulfills the required sealing effect between the inlet / outlet guides and the roller bar without any further adjustment work. It is recommended that at least one spring device is provided for biasing the sealing strip in the receiving groove. About this spring device is thereby sealed when pressing the inlet / outlet guides the gap between the rolling beam and inlet / outlet guides just by the spring-loaded sealing strip, whereby the media are retained against dripping on the rolling stock.
  • the arrangement of the sealing strip in the receiving groove comprises a retaining device for the sealing strip, on these, the sealing strip if necessary, be kept in a non-operational position.
  • the retaining device is designed for the arranged in the receiving groove sealing strip as at least one screw.
  • the rolling mill according to the invention is generally designated 1.
  • the roll stand 1 is provided with support and / or work rolls 2,3,4,5 and is used for rolling sheets or strips. It is in the Fig. 1
  • the drawing shows a partial side view of a roll stand 1, comprising an upper work roll 3, a lower work roll 4 and an upper support roll 2 and a lower support roller 5, not shown separately.
  • the rolling mill 1 according to the invention comprises in the illustrated embodiment, see Fig. 1 the drawing, arranged between the work roll chocks 7, the upper work roll 3 associated rolling beam 8 and an adjacent this rolling beam 8 arranged inlet / outlet guide 9 for a medium, eg cooling water, emulsion or the like.
  • the rolling mill 1 further comprises sealing means 10 for preventing dripping of, for example, cooling water on the rolling stock, see the Fig. 2 the drawing with a detailed representation of this sealing means 10 having partial area of the roll stand 1.
  • sealing means 10 for preventing dripping of, for example, cooling water on the rolling stock
  • Fig. 2 the drawing with a detailed representation of this sealing means 10 having partial area of the roll stand 1.
  • FIG. 1 The drawing illustrated embodiment are, moreover, the main design features a rolling stand 1 while the skilled person known and therefore not shown in detail in the drawing or the structural details shown in detail in detail not described in detail.
  • the sealing means 10 for preventing dripping example of cooling water on the rolling stock as in the illustrated embodiment a between the rolling beam 8 and the inlet / outlet guide 9 arranged sealing strip 11 is formed, see in particular the Fig. 2 the drawing.
  • a rolling stand 1 results for the first time, in which the medium is retained on the rolling stock before dropping by sealing the gap between rolling beam 8 and inlet / outlet guide 9 by the sealing strip 11 during pressing of the inlet / outlet guide 9 ,
  • the inventive arrangement results in a particularly favorable as well as robust, low-wear and reliable solution.
  • the sealing strip 11 is arranged in a arranged in the region between the rolling beam 8 and the inlet / outlet guide 9 receiving groove 12; the receiving groove 12 is arranged here by way of example in the roll bar 8.
  • the sealing strip 11 in the receiving groove 12 is further biased against the rolling beam 8.
  • the sealing strip 11 thus fulfills the required sealing effect between the inlet / outlet guide 9 and the rollers / roller fittings without further adjustment.
  • a spring means 13 see again Fig. 2 .
  • this spring means 13 while pressing the inlet / outlet guide 9, the gap between the rolling beam 8 and inlet / outlet guide 9 just sealed by the spring-loaded sealing strip 11, whereby the said media are retained on the rolling stock before dripping.
  • a pneumatic system or a hydraulic system is also conceivable to provide deviating means or systems for forming a bias.
  • the sealing strip 11 in the rolling stand 1 according to the invention is further provided, see again the Fig. 2 the drawing, which includes the arrangement of the sealing strip 11 in the receiving groove 12 a retainer 14 for this sealing strip 11, about this, the sealing strip 11 may be kept in a non-functional position and prevented from falling out, if desired.
  • This retaining device 14 for the arranged in the receiving groove 12 sealing strip 11 is presently designed as a screw 15.
