Definitions

  • a servo valve is preferably provided for each adjusting cylinder and a multi-way valve is provided for each piston surface. Separate servo valves are recommended in order to independently set the work rolls on one side or the other and consequently to be able to vary the roll gap across the gap width.
  • the high-pressure control pump 12 pressurizes the pressure medium or the pressure fluid via the servo valves 14 and multi-way valves 15 Allows piston surfaces A1, A2 to act, the control pump 13 for quick adjustment, which works with a larger flow rate at low pressure, lifts the rollers until they come into contact with the pressure plates 7, 7 '.
  • the support and work rolls 4, 5 are kept in contact via balancing cylinders, not shown.
  • the roll gap can also be preset via roll gap measuring devices.
