Induction Heaters

Challenges

  • Tight edges of hard rolled strip are not adequately countered by mechanical actuators
  • Strip breaks reduce productivity, yield and delivery performance

Solution

  • An alternating magnetic field induces eddy currents that generate heat directly on the roll surface

Technical advantages

  • Tight strip edges are greatly reduced
  • Higher rolling speeds and lower edge tensions
  • High-accurate heating of work rolls in strip edge area
  • Reduced risk for strip breakage during rolling

Quality

  • Optimized flatness over the complete strip width
  • Stable rolling process
