Definitions

  • This invention relates to improvements in a four high mill of a paired-roll-crossing type.
  • a mill according to the first part of the main claim is known from the FR-A-1413732 and partly from the CH-A-295443.
  • Those rclling mills include means for separately setting the left and right roll gaps, oil hydraulic jacks for roll bending, and a paired-roll-crossing mechanism which can be adjusted to move the pair of the upper work roll and backup roll and the pair of the lower work roll and backup roll to cross each other at predetermined angles with respect to a line normal to the rolling direction. In this way they can attain the end described above.
  • This invention is aimed at overcoming the drawbacks of the proposed mills, and it provides a four high mill of a paired-roll-crossing type which comprises a housing, an upper and a lower backup roll bearing cases held within the housing, an upper and a lower equalizer beams in contact, respectively, with the uppermost and lowermost surfaces of said bearing cases and made both movable upwardly and downwardly, pairs of work rolls and backup rolls in four high arrangement, upper and lower work roll chocks installed inside said bearing cases characterized in that roll-crossing means are mounted in said housing to turn said bearing cases about a common vertical axis on the same horizontal plane so that said upper and lower pairs of rolls can cross each other, and means for separately setting the left and right roll gaps between said upper and lower work rolls.
  • work roll bending means may be mounted at both ends of the work rolls.
  • the numeral 1 indicates a slab or strip of steel to be rolled by a pair of work rolls 2, 2', which are held one above another and supported, respectively, by work roll chocks 6, 6' as shown.
  • a pair of backup rolls 3, 3' in rolling contact with the non-working sides of the work rolls 2, 2', are held within upper and lower bearing cases 7, 7' for the backup rolls.
  • the pair of screw-down devices 11 equipped with the screws 4 constitute means for separately setting the left and right roll gaps as desired between the upper and lower work rolls 2, 2'.
  • the upper and lower backup roll bearing cases 7, 7' are held in a suitably spaced relation within the housing 8 so they may move upwardly and downwardly along the housing frames and also, as will be described later, they may turn about their common vertical axis.
  • the upper and lower work roll chocks 6, 6' are vertically slidably housed in the upper and lower backup roll bearing cases 7, 7'.
  • Between the both ends of the backup roll bearing cases 7, 7' and those of the work roll chocks 6, 6' are interposed roll-bending devices (oil hydraulic jacks) 5, as shown in Fig. 1.
  • equalizer beams 21,21' are disposed between the upper backup roll bearing case 7 and the screws 4 and between the lower bearing case 7' and the hydraulic reduction cylinders 10, which are movable upwardly and downwardly but are horizontally constrained unmovably by the inner walls of the housing 8.
  • Jacks 13a, 13b, 13c, and 13d are supported by brackets 20, 20', which in turn are provided, as shown, on the upper and lower portions on both sides of the housing 8. These jacks are operated so as to turn the upper and lower backup roll bearing cases 7, 7' on the same horizontal planes about their common vertical axis.
  • the brackets 20, 20' combine with the jacks 13a to 13d to constitute roll-crossing devices disposed in the housing 8.
  • the numeral 15 designates a cylinder for balancing the inner housing, mounted on top of the housing 8, with a rod 14 suspending the top roll assembly.
  • Radial bearings 16, 16' for the work rolls 2, 2' are supported themselves by the work roll chocks 6, 6'.
  • the work rolls 2, 2' (Fig. 3 showing only the roll 2' for simplicity) are supported at one ends by thrust pads 18 through thrust bearings 17.
  • the thrust pads 18 are secured to the upper and lower backup roll bearing cases 7, 7' with chock plates 19.
  • the line V-V be the centerline of width of a slab or strip being passed through the rolls (hereinafter called the "passing line")
  • the line X-X be a straight line that extends across the middle point of length of the rolls and parallel to the passing line V-V
  • the line Y-Y be a straight line at right angles to the line X-X
  • the intersection of the passing line V-V and the line Y-Y be W.
  • the initial roll gaps c ⁇ , e 2 between the upper and lower work rolls 2, 2' can be adjusted by suitably operating the left and right screw-down devices 11. Also, proper control of the roll-bending forces F 1' F 2 is made possible by the roll-bending devices 5.
