Then operate the linkage reversion of whole skin pass mill group, observe the strip steel 7 plate shape situation of change after smooth；Observing the ruuning situation of strip steel 7 reversion, when on the reel arriving uncoiler 1 that reverses without the strip steel 7 of shape wave defect after smooth, operation skin pass mill group stops linkage reversion simultaneously；
3) operation coiling machine 6 single action reversion, operation conveyer device 2 single action reversion simultaneously, strip steel 7 is refunded uncoiler 1 place, and free hanging is below the reel of uncoiler 1, until the position, boundary at the position and smooth position that there is shape wave defect on strip steel 7 is positioned at slicing machine 4 place and stops；Operation coiling machine 6 stops single action reversion and conveyer device 2 stops single action reversion；
4) operation slicing machine 4 is sheared, and without after smooth strip steel 7 cutting that there is shape wave defect when skin pass mill group is carried out threading, operation coiling machine 6 draws off after the strip steel 7 that there is shape wave defect is batched；
5) operation conveyer device 2 single action rotates forward, and the strip steel 7 without shape wave defect is sent to the reel of coiling machine 6, the stopping when free hanging stretches without the strip steel 7 of shape wave defect；Then operation conveyer device 2 and uncoiler 1 linkage rotate forward, and the head obtained after being sheared by strip steel 7 is sent into coiling machine 6 and batched；
6) after the head of strip steel 7 completes to batch, and when ensureing that the initial position of raw material that there is shape wave defect on strip steel 7 is between planisher 3 entrance and conveyer device 2, operation skin pass mill group carries out building, and leveling roll roll gap is closed；
7) after skin pass mill group completes to build, start skin pass mill group and run, and controlling planisher 3, to carry out secondary smooth, until completing batching of strip steel 7.
In step 1) described in " build " refer to and make strip steel 7 have tension force by exporting tensioner.Hot rolling loudspeaker volume is reinstalled on the uncoiler 1 of skin pass mill group, then carries out starting, threading；Strip steel 7 completes threading, build after, start skin pass mill group and run, and control the strip steel 7 that loudspeaker are rolled up by planisher 3 and carry out smooth.
In step 2) in first when after smooth strip steel 7 without shape wave defect run the reel to coiling machine 6, and after completing the batching of 1～5 circle on reel without the strip steel 7 of shape wave defect, skin pass mill group is out of service, release tension force；The roll gap of leveling roll opened by operation planisher 3.Owing to after smooth, strip steel 7 without shape wave defect runs the reel to coiling machine 6, and after completing the batching of 1～5 circle on reel without the strip steel 7 of shape wave defect, skin pass mill group is out of service, therefore it is capable of by above-mentioned steps, as it is shown in figure 1, coiling machine 6 is to strip steel 7 smooth between planisher 3.
Owing to the follow-up strip steel 7 being taken up on reel can be made under tension to be close on reel original strip steel 7, if the strip steel on reel 7 exists shape wave defect, the follow-up strip steel 7 being wound on reel will replicate the shape wave defect of original strip steel 7 on reel under tension.Owing in above-mentioned steps, strip steel 7 without shape wave defect completes batching of 1～5 circle on reel, therefore, it is possible to observe, whether the strip steel 7 being wound on the reel of coiling machine 6 replicates deformation, reappears shape wave defect.
In step 2) in carried out above-mentioned steps after, then operate the linkage reversion of whole skin pass mill group, observe strip steel 7 plate shape situation of change after smooth；Observing the ruuning situation of strip steel 7 reversion, when on the reel arriving uncoiler 1 that reverses without the strip steel 7 of shape wave defect after smooth, operation skin pass mill group stops linkage reversion simultaneously.It is operated by skin pass mill group linkage reversion, so that be taken up the strip steel 7 that machine 6 batches to be retired uncoiler 1 place；Simultaneously because when on the reel arriving uncoiler 1 that reverses without the strip steel 7 of shape wave defect after smooth, operation skin pass mill group stops linkage reversion；Therefore can avoiding returning in the process of strip steel 7 in reversion, the strip steel 7 return batches again on loudspeaker are rolled up.
