Inductive edge heating
Aluminum cold rolling millsEfficiency
- Reduced yield loss due to edge trimming
- Tremendous decrease of energy consumption compared
to conventional hot edge spray system
Quality
- Prevention of strip breakages
- Absolute strip flatness improved by 15 I-Units
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
