SPIDEM (CLECIM), REVERSING ROLLING MILL
Production data: Real productivity achieved:
AA 1xxx – 8xxx series (reroll for after foils tock) up to 13.2 ton/h
AA 1xxx – 3xxx series (reroll for sheet coils) up to 11.6 ton/h
AA 5052 (reroll for hard sheet coils) up to 8.3 ton/h
Main mill advantages:
- All table rollers are driven, which is an important factor of quality
- The entry and exit guides are powerful, which is advantage for alloys
- Largely sized pinion stand
- Quite high rolling speed can be used for final passes (140 m/min.) – productivity
- Low thickness reachable – 3.0 mm
- Exit edge trimme on-off device (better quality of reroll edges & higher productivity)
- Exit and entry side table and crop shears (provide a min. process scrap & better quality)
