Definitions

  • the invention relates to a roller cooling and / or Lubrication device for cold strip rolling mills, especially fine strip and film rolling mills, assigned to the individual rolls the side plates of the roller stands of one or more Rolling stands attached to the nozzle bars into which the width of the Roller spray nozzles built in and relative to them assigned rollers independently of one another transversely to the direction of travel of the rolled strip can be adjusted in planes parallel to the strip plane are used to regulate the belt tension over the bandwidth a change in the effective roll bale diameter and / or influencing the roller lubrication with a pressure and / or quantity and / or temperature controlled supply of Rolling oil or emulsions.
  • the flatness control of the rolled strip at one Cold strip rolling mill which with a from DE 34 19 261 C3 known roller cooling and / or lubricating device generic type is based on a change of the spray pattern on the surface of the work rolls sprayed rolling oil or sprayed emulsions.
  • the spray pattern is changed by adjusting each Work roll of the rolling mill associated nozzle bar relative to Work roll independent of the other nozzle bar across Belt running direction in a plane parallel to the belt plane and a pressure and / or quantity and / or temperature controlled Supply of rolling oil or emulsions causes.
  • Fine and foil tape on a known one Flatness control equipped quarto or sexto roll stand rolled is characterized by high quality with regard to dimensional and shape accuracy as well as flatness.
  • a disadvantage of roller cooling and / or lubricating devices The generic type for cold strip rolling mills is the insufficient one Accessibility of the nozzle bars with the spray nozzles and the associated control valves, so that repair and Maintenance work on the nozzle bars cumbersome and are time consuming.
  • the invention has for its object the regulation of Strip flatness in cold strip rolling mills using the generic type Roll cooling and / or lubricating device to optimize unwanted strip tension deviations in zones leveled rolled strip, and the accessibility of the in the Nozzle bar of the roller cooling and / or lubricating device built-in spray nozzles and their associated control valves in the With a view to simplification and acceleration of to improve necessary repair and maintenance work.
  • the spray angle of the spray nozzles of the nozzle bars with reference on the rolls, which in the roll cooling and / or lubrication device by pivoting the nozzle bar the longitudinal axis of the bar is adjustable, represents another Command value in addition to the adjustability of the nozzle bar relative to the respective assigned roller across Direction of tape travel as well as the change in quantity, pressure and the temperature of the rolling oil sprayed onto the rolls or the sprayed emulsions to change the spray pattern on the Roll surface in the context of a strip flatness control
  • Spray angle of the spray nozzles as an additional manipulated variable enables optimization of the strip flatness control.
  • the four-high rolling mill stand 1 according to FIG. 1 is not by two roller stand shown formed in which in not shown chocks a lower and an upper Work roll 2, 3 and a lower and an upper backup roll 4, 5 are rotatably mounted.
  • Roll cooling and / or lubrication device for the work rolls 2, 3 and the support rollers 4, 5 each consist of a nozzle bar 7, 8 for the work rolls 2, 3 and a nozzle bar 9, 10 for each the support rollers 4, 5.
  • nozzle bars 7-10 are across the width of the rollers Spray nozzles 11 with upstream, as solenoid valves trained control valves 12 for applying cooling oil and / or emulsions installed on the rollers 2-5.
  • the the Backing rolls 3, 4 assigned to the nozzle bars 9, 10 are stationary, while the nozzle bars 7, 8 assigned to the work rolls 2, 3 in the direction of arrow b, c in the direction of its longitudinal axis 13-13 transversely to the tape running direction a over the bandwidth and around their longitudinal axis 13-13 are pivotable.
  • the respective supply of rolling oil and / or emulsions the adjustable nozzle bar 7, 8 and the stationary Nozzle bar 9, 10 becomes pressure and / or quantity and / or temperature controlled.
  • nozzle bars 7, 8 At the two ends 15, 16 of the work rolls 2, 3 assigned two nozzle bars 7, 8 are adapters 17 rotatable and displaceable mounting of the nozzle bars around and in Direction of the longitudinal axis 13-13 on two hollow journals 18, 19 attached, in side plates 20, 21 on the two Roller stands, not shown, of the four-high rolling mill stand 1 are installed, the supply of the coolant or Emulsions to the spray nozzles installed in the nozzle bars 7, 8 11 and the associated control valves 12 through a feed line 22 in a side plate 20, the cavity 23 of the in Side plate 20 built-in bearing pin 18, the interior 24 of the adapter 17 seated on the journal 18 and the Distribution channel 25 of the nozzle bars 7, 8 takes place.
  • the supply of the coolant to the nozzle bars 7, 8 can also by a feed line 22 in each of the two side plates 20, 21, in these built-in hollow journals 18, 19, the on this seated adapter 17 and the distribution channel 25 of the Nozzle bars are made.
  • the connecting cables for the control valves 12 of the spray nozzles 11 the nozzle bars 7, 8 are in several flexible protective tubes 30 merged, the length of the connecting cable Control valves is dimensioned such that a pivoting of the Nozzle bar 7, 8 around the bar longitudinal axis 13-13 is possible.
  • Temperature sensor 31 for detecting the size of the thermal Roll bales outside the maximum range and in Roll center by measuring the temperature of the roll surface integrated to adjust the roll gap model.
  • Deviating from the above-described embodiment of the new roller cooling and lubrication device Possibility of an additional movability and a Pivotal movement of the nozzle bars 9, 10 for the support rollers 4, 5 in the direction of or around the longitudinal axis of the beam to provide.
  • the nozzle bars 7, 8 can be moved for the work rolls 2, 3 and the nozzle bar 9, 10 for the Back-up rolls 4, 5 together or independently or only a movability of the nozzle bars 7, 8 for the Work rolls 2, 3 from a maintenance position remote from the roll in the working position and from the working position to the Maintenance position should be considered.
