Definitions

  • the invention relates to a method for cleaning rollers and / or rolls in strip casting plants, rolling mills and / or Belt process lines, especially skin pass rolls or similar rolling mills, for production and / or Treatment of metal strips, after which the rollers and / or Roll each with at least one cleaning nozzle Cleaning liquid and the Cleaning nozzle along the roller or roller in question going back and forth.
  • metal straps also includes steel straps.
  • JP 05 042309 A makes it part of the prior art the technology, a cleaning nozzle with adjustable distance to position against a roller. This measure may in itself a certain improvement in the cleaning effect enable because of this different Diameters of the roll or roll concerned will be carried.
  • the invention has for its object a method for Cleaning of rolls and / or rolls in belt casting machines, Rolling mills and / or belt process lines, especially skin pass rolls or the like rolling mills to indicate which through a particularly efficient cleaning effect distinguished and an adaptation to different roller or roll diameter as well as on different strip materials and belt speeds. Moreover a device is to be created to carry out this cleaning method is particularly suitable and is characterized by simple and functional design.
  • the cleaning of the relevant rolls or rollers at least considerably relieved, if not superfluous in some cases.
  • the relevant Metal tape when cleaning liquid rolls over a roll is acted upon, consequently the relevant Metal tape in the course of cleaning on the roll can support against the fluid pressure. Because preferably with a fluid pressure of at least 100 bar cleaned.
  • the cleaning fluid can be anti-corrosive Additives are added.
  • the invention also relates to a device for Carrying out the claimed process, with rollers and / or rollers for generating and / or treating one Metal strip and at least one of the respective Cleaning nozzle assigned to rollers or rollers, the Cleaning nozzle along the roller or roller in question traversed.
  • This device is characterized in that that the cleaning nozzle on the piston rod of a controllable or adjustable cylinder piston assembly is attached or vice versa, which on the roller to be cleaned or Role is directed.
  • the cleaning nozzle also on the cylinder of the cylinder piston arrangement can be attached if the piston rod is a stationary Takes position and the cylinder against the relevant Roller or roller can be moved.
  • the cylinder piston assembly can be used as pneumatic cylinder or hydraulic cylinder be trained.
  • an in constructively relatively simple construction realized the cleaning nozzle in the course of a change in distance against the relevant roll shell or To move the roller jacket.
  • the cleaning nozzle is according to the invention designed as a rotary nozzle, which is characterized by has a particularly good cleaning effect.
  • the spray angle between the relevant roller or roller and the cleaning nozzle, z. B. is adjustable between 60 ° and 120 ° the cleaning nozzle taking into account the respective Diameter ratios optimally against the one to be cleaned To be able to turn on the roller or roller. It can also succeed in that the angle of inclination of the cylinder piston assembly with the cleaning nozzle opposite the one in question Roller or roller is adjustable. In both cases the setting can also be made by means of a regulation.
  • FIG. 1 In the figures is a device for cleaning rollers 1 in skin pass mills in the course of treating a metal strip M shown.
  • the rolls 1, namely both work rolls 1a and backup rolls 1b are each by means of at least one cleaning nozzle 2 with cleaning liquid applied.
  • the cleaning nozzles 2 are along the relevant one Rollers 1 can be moved back and forth.
  • the cleaning nozzles 2 on the piston rod 6 of a controllable or adjustable cylinder piston assembly 7 attached, which directed to the rollers 1 to be cleaned and on the traversing carriage 4 are mounted.
  • the distance A between the cleaning nozzles 2 and the roller jacket 8 of the relevant rollers 1 is adjusted or controllable. Consequently, even then a constant distance A between the cleaning nozzles 2 and set up the relevant rollers 1 when the rollers 1 are ground be or rolls 1 of different diameters be used. Because the distance A between that Roller jacket 8 is made by moving the cleaning nozzles 2 kept constant, namely less than 100 mm. Moreover the traversing speed of the reciprocated Cleaning nozzles 2 depending on the belt speed and / or the strip material and / or the strip surface set or regulated.
  • the cleaning nozzles 2 are designed as rotary nozzles.
  • the spray angle between the rollers 1 and the cleaning nozzles 2 is adjustable, e.g. B. adjustable between 60 ° and 120 °.
