Definitions

  • This invention relates to rolling mills of the type having, in addition to the pair of driven rolls, a second pair of rolls which are normally only rotated by the action of a workpiece moving in the direction of its length between, and in engagement with, these rolls.
  • Beam and section mills are mills of this type in that they have a pair of driven horizontal rolls and at least one pair of vertical rolls. The rolls constituting the or each pair of vertical rolls are positioned on opposite sides of the passline between the horizontal rolls and they are freely rotatable about their vertical axes.
  • the present invention resides broadly in a rolling mill of the type set forth in which each of the normally non-driven rolls has a separate electric motor means associated with it by which the roll can be rotated so that when the workpiece and the roll come into engagement the engaging surfaces of the roll and workpiece are moving in the same direction.
  • the electric motor means to rotate the rolls while the workpiece is passing through the mill between the rolls but simply to adjust the direction of rotation of the rolls and preferably the speed also so that they are substantially matched when the workpiece engages with the rolls.
  • a universal rolling mill comprises a pair of horizontal rolls 2, 4 each having roll necks rotatable in bearings in bearing chock assemblies [chocks] 6, 8, respectively.
  • the chocks are arranged in a mill housing strucutre 10.
  • a pair of vertical rolls 12, 14 are freely rotatable on bearings 16, 18 which surround a pair of stationary shafts 20, 22 mounted in bearing chock assemblies [chocks] 24, 26, respectively.
  • the horizontal rolls are driven by electric motors (not shown) by way of drive shafts 28, 30 but the vertical rolls 12, 14 are normally undriven and rely on the movement of the workpiece between the vertical rolls and in engagement therewith to cause the rolls to rotate.
  • each of the chocks 24, 26. which are associated with the vertical rolls has electric motor means associated with it.
  • each chock has two or more recesses 32, 34, 36 in which are located electric motors of the linear type, indicated by references 38, 40, 42.
  • These motors consist of stationary windings which, when energised, interact with the metal of the adjacent roll 12, 14, to cause it to rotate. Motors of this type are available from Linear Motors Limited, Empress Road, Loughborough, England. Excitation of the motors applies a turning force to the rolls sufficient to cause them to rotate or, if they are rotating in the opposite direction, to have a braking and then reversing effect on these rolls.
  • a workpiece W is passed between the pairs of rolls causing the vertical rolls to rotate such that the peripheral speed of the vertical rolls matches the linear speed of the workpiece.
  • the vertical rolls continue to rotate about their vertical axes.
  • the workpiece is halted on a run-out table (not shown) on the opposite side of the mill and the drive to the horizontal rolls is reversed and then the driven rolls of the run-out table are reversed to feed the workpiece back into the mill.
  • the linear motors are actuated to impart a turning force on the vertical rolls in a direction opposite to that in which they are rotating.
  • the linear motors are controlled so that, when the workpiece re­enters the mill, at least the rolls are rotating in the correct direction and preferably the peripheral speed of the vertical rolls is substantially matched to the linear speed of the entering workpiece.
  • each vertical roll 12, 14 has three motors 38, 40, 42 associated with it whereas in the Figure 3 arrangement only two motors 38, 42 are employed.
  • Each motor is conveniently of the form shown in Figure 4 in which a housing 50 carries the windings on an arcuate stator.
  • the stator has terminals 44 in a terminal box 46 and passages 48, 52 enable a cooling fluid to be circulated through the stator housing.
  • the pair of vertical rolls may have their longitudinal axes in the same vertical plane which contains the longitudinal axes of the horizontal rolls.
  • the mill may have one pair of vertical rolls arranged with their longitudinal axes in a vertical plane parallel with that containing the longitudinal axes of the horizontal rolls.
  • two pairs of vertical rolls may be provided and located upstream and downstream respectively of the horizontal rolls.
