Solitions for cold rolling mills

Cold rolling mills

Precise knowledge of rolling mill technology facilitates the use of sophisticated technologies in hydraulic screw-downs with precise thickness gauge controls in combination with dynamic drive technology in three-phase AC and DC technology. We have developed comprehensive concepts that we use as solutions in the cold rolling industry.

Our specific products:

Screw-down

  • Hydraulic screw-down for long- and short-stroke cylinders

  • Hybrid screw-down with pre-screw-down
  • Automatic calibration with storage of pass parameters and feasibility studies
  • Rolling force control with envelope protection
  • Position control with envelope protection
  • Seamless switching between operating modes

Thickness gauge control

  • Monitor control (FBC) with downtime pilot control
  • Feed forward control (FFC) with adaptive shift register
  • Mass flow control (MRC) with feasibility studies
  • Skin pass control
  • Elongation control
  • Rolling effectiveness pilot control
  • Tension regulation / speed control

Drive control
