Aluminum foil roughing mill is a machine that rolls aluminum sheet and strip coils with a material of 0.5mm or less through several passes to make them into aluminum foil of 2×0.0045mm or more thickness.
Introduction of aluminum foil rolling mill.
A set of aluminum industry machinery and equipment mainly used for aluminum foil rolling, processing and refining.
Operation and key points
1. Pre-rolling preparation
1.1 Check the operating status of each system to confirm
1.2 Change rolls according to the schedule and check
a) Nozzle status position, blockage
b) Confirm the position of the rolling line
c) Oil mist pipe connection should be good
1.3 Prepare and load the material according to the plan and pay attention to
a) Remove the surface layer to prevent dust and tape from entering the mill to prevent roll marks
b) Confirm the quality of the roll end face? Light sharp bruises handled into a rounded shape.
2. Speed-up process
2.1 Newly changed into the work roll rolling
2.1.1 Heat the rolls for 3~5min according to the normal rolling roll running condition; the heated rolls can be less.
2.1.2 AFC in the nozzle oil spray ratio control in the lower limit of the process table can quickly reach the ideal plate shape after recovery.
2.1.3 Use the largest possible post-tension and pre-tension to stabilize the post-recovery.
2.1.4 Use the appropriate rolling force, bending roll force, tilt value? Mainly rely on the usual experience accumulation to avoid one side loose, one side tight or both sides too loose and too tight.
2.1.5 Speed up as soon as possible to reach the target thickness.
2.2 Normal rolling process speed up
2.2.1 According to the value of each parameter of the upper roll preset rolling force, bending roll force, tilt value can get smooth plate shape.
2.2.2 The speed can be increased in one step not to adjust the plate before the target thickness is relatively small tension value is not conducive to spreading.
2.3 The processing of slippage and open seam breakage during speed rise is mainly in the rough rolling four times.
2.3.1 Shorten the time of rolling deformation increase the rolling force increase the back tension appropriate to increase the front tension.
2.3.2 Improve lubrication conditions using a lower oil temperature open seam at the spray oil often open.
2.3.3 Still can not be rolled when the roll change.
3. Intermediate rolling process
3.1 Good alignment, especially wide material will produce a loose side and a tight side, thus causing the cracked edge of the second rib loose phenomenon affect the next production.
3.2 AFC should be regularly calibrated zero plate type rolls in running condition.
3.3 When the second rib is loose, the ratio of oil spray in AFC can be reduced.
3.4 Broken belt with oil flushing waste for a long time should be sprayed oil all open to avoid roller type change.
3.5 Adjustment when wrinkling, folding, string layer, loose roll
