Definitions

  • a drive system is particularly adapted to use in conjunction with a hot .rolling mill that receives continuously cast, hot metallic strand, particularly strands of copper and copper alloys, and produces a high quality narrow strip with precisely controlled dimensions, profile and camber and with a high reduction.
  • the mill has only two working rolls with a comparatively small diameter, each mounted for rotation in chock blocks. One roll is fixed and the other roll and its chock blocks are movable vertically under the control of a pair of hydraulic cylinders to vary the gap between the rolls.
  • this mill can produce a bite in excess of 2.54 cm (one inch) and approaching 5.1 cm (two inches) and bite ratios of as low as 5:1 without slippage.
  • each roll 42 is driven independently by one of the hydraulic motors 46. There is therefore no gearing or other power transmission coupling which is usually employed to transmit power from one driven roll to another slave roll or rolls.
  • the motors are coupled directly to the rolls through the spline coupling assembly 80 including a "roll half" 80a found integrally with one end of each roll and mating "motor half” 80b mounted on the drive shaft 46a of the motor.
  • the coupling halves 80a and 80b are simply mated and bolted to one another. This coupling avoids transmission power losses and greatly reduces the bulk, complexity and cost of the roll drive. It also allows rolls to be changed easily.
