Challenges

  • Avoiding undesired profiles at the strip edge during cold rolling of aluminum strip

Solution

  • Specific high-accurate heating of work roll barrel in the strip edge area by moveable induction spools. Rolling oil based inductor cooling

Technical advantages

  • Precise prevention of tight edges even at high rolling temperatures
  • Improved strip flatness
  • Reduced yield loss by edge trimming
  • Compact design and easy installation
