Technological skin pass mill controls (ELG, HGC)

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

Technical advantages

  • Calculation of force => maintenance free => no load cells
  • Roll change without line stop possible

Quality

  • Highest product quality

Productivity

  • Minimization of downtime
