Technological skin pass mill controls

Challenges

  • Defined roughness and flatness
  • Suppress Lüders lines

Solution

  • Technological control system with hydraulic gap control (HGC) and elongation control (ELG)
  • HGC force control with pressure transducer
  • Also available with X-Shape Flatness Measurement and Control

Technical advantages

  • Calculation of force => maintenance free => no load cells
  • Maintenance-free calculation of rolling force, no direct force measurement required
  • Roll change without line stop possible

Quality

  • Highest product quality

Productivity

  • Minimization of downtime
