Abstract
1,223,188. Rolling; stretching. METAL BOX CO. Ltd. 9 May, 1969 [7 June, 1968], No. 27292/68. Headings B3E and B3M. A rolling mill for metal strip comprises a pair of back-up rolls 7, 8, a pair of work rolls 9, 10 and a pair of support rolls 11, 12 for the work rolls and movable relative to the work rolls. The strip 1 is tensioned by bridle rolls 4, 5, 16, 17 and by a pair of driven rolls 13, 14. The work rolls 9, 10 are mounted in a housing (20), Fig. 3 (not shown), which is rotatable to facilitate initial insertion of the strip. The axis of the lower back-up roll 7 is fixed and the upper back-up roll 8 moved by worm 71 and screw 73 arrangement after rotation of the housing. The support rolls 11, 12 are similarly mounted and a normal or hydraulic spring 82 may be provided between the screw 81 and a load-cell 80 of the support roll 11. Load-cells 70, 75 are also provided on the adjustment for the rolls 8, 12. The rolls are driven through gearing, Fig. 5 and 6 (not shown), although the work rolls may be free. The position of the support roll 12 is adjusted to provide the required wedge angle (83), Fig. 1 (not shown), and the other support roll 11 moved to a floating position. The degree of reduction is determined by the back-up screw adjustment and the support roll 11 screw adjustment. The load is influenced to a lesser extent by the strip tension and the torque applied to the rolls. Sensing devices (not shown), may be provided to measure the strip thickness before and/or after rolling and the signals used to operate the screw 81 of the support roll 11, and/or the tension applied to the strip by the bridle rolls 4, 5, 16, 17. In an alternative embodiment, Fig. 7 (not shown), the support rolls are in rolling contact with the work rolls. The diameters of the work rolls need not be the same.
