Abstract
The invention discloses a method for reducing the annealing defect of an aluminum product. In the stretch-straightening and washing process of an aluminum strip, after a material tail is separated from the strip, the aluminum strip and the two ends of an aluminum strip on the outermost ring of an aluminum roll are welded and fixed at the rolling position of the aluminum strip till the whole aluminum strip is rolled. After the aluminum strip is stretch-straightened and washed and is rolled, the outer ring of the aluminum roll is fixed, and then a finished product annealing procedure is executed. According to the method for reducing the annealing defect of the aluminum product, the two-end welding manner is adopted for welding and fixing the aluminum strip obtained after the material tail is separated from the strip and the aluminum strip on the outermost ring, the portion with unstable rolling tension and small rolling tension and the aluminum roll on the portion with normal rolling tension can be isolated, and the problem that the layers of the aluminum roll within the number of the welding layers of the aluminum strip are loosened can be effectively avoided. Therefore, annealing bind-damaging defects caused by layer loosening are overcome.
Description
Technical field
The invention belongs to aluminium process for processing technical field, concrete is a kind of method reducing aluminum anneal defect.
Background technology
Generally need the aluminum strip of finished products after the cleaning of straightening technique, aluminium volume outer ring need be fixed, fixed form usually one of following three kinds or certain two kinds with the use of.
1) adhesive tape is used to hand over stub bar to cling;
2) longitudinally use aluminium strip that aluminium is rolled up outer ring to tightly wrap, aluminium strip is generally used for the aluminium of thickness≤1.0mm;
3) longitudinally use steel band aluminium to be rolled up outer ring urgent, steel band is generally used for the aluminium of thickness G reatT.GreaT.GT1.0mm.
Above-mentioned aluminium volume outer ring fixed form mainly deposits quality problems both ways: longitudinally beat the aluminium volume of steel band after annealing, due to the thermal distortion of aluminium and the thermal deformation coefficient of steel different, cause aluminium can produce ankle injury of significantly annealing in steel band corresponding position after annealing.
In addition, when crossing the cleaning of straightening operation before aluminum strip finished products, in the de-band of material tail and threading are run, coiling tension is less and unstable, aluminium is caused to roll up outer perimeter section strip coiling tension force inadequate, there is the slight staggered floor phenomenon of interlayer in annealing process, thus cause aluminium volume outer ring to occur the sticky wound of intensive point-like.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of method reducing aluminum anneal defect, can effectively alleviate, effectively can solve that the annealing produced because of aluminium unwinding layer is sticky hinders defect.
For achieving the above object, the invention provides following technical scheme:
Reduce a method for aluminum anneal defect, in aluminum strip straightening cleaning process, when after the de-band of material tail, batch place in aluminum strip, the two ends that aluminum strip and aluminium roll up the aluminum strip of outmost turns are welded and fixed, until all aluminum strip have been batched; After aluminum strip straightening has been cleaned and batched, aluminium is rolled up after outer ring is fixed and entered finished products operation again.
Further, after aluminum strip straightening has been cleaned and batched, utilize aluminium strip or steel band, along aluminium volume inner core axial direction due, aluminium is rolled up outer ring and fixed.
Beneficial effect of the present invention is:
The present invention reduces the method for aluminum anneal defect, by adopting the mode of two ends welding, the aluminum strip that material tail takes off the aluminum strip after band and outmost turns is welded and fixed, the capable isolation can be involved in by coiling tension is unstable and coiling tension smaller portions and coiling tension normal segments aluminium, effectively can prevent aluminum strip from welding the loose layer problem of the aluminium volume within the number of plies, thus solve that the annealing produced due to loose layer is sticky hinders defect.
In addition, by axially beating steel band, aluminium volume after annealing, it contacts maximum forced position with steel band be band two edge, and aluminum strip needs trimming when manufacturing a finished product, even if two edge occur that steel band ankle injury also can be cut away by as slitter edge, the quality of product can not be affected.
Accompanying drawing explanation
In order to make object of the present invention, technical scheme and beneficial effect clearly, the invention provides following accompanying drawing and being described:
Fig. 1 be existing a kind of utilize aluminium strip or steel band fix aluminium volume outer ring time structural representation;
Fig. 2 is for after the de-band of material tail, and aluminum strip and aluminium roll up the welding position schematic diagram of outmost turns;
Fig. 3 be the present invention reduce in the method for aluminum anneal defect utilize aluminium strip or steel band fix aluminium volume outer ring time structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described, can better understand the present invention and can be implemented, but illustrated embodiment is not as a limitation of the invention to make those skilled in the art.
The present embodiment reduces the method for aluminum anneal defect, in aluminum strip straightening cleaning process, when after the de-band of material tail, place is batched in aluminum strip 1, the two ends that aluminum strip 1 and aluminium roll up the aluminum strip of outmost turns are welded and fixed, until all aluminum strip 1 have been batched, as shown in Figure 2, each spot welding position B as shown in Figure 3 for the position A of welding.After aluminum strip 1 straightening has been cleaned and batched, aluminium is rolled up after 2 outer rings are fixed and entered finished products operation again.Concrete, after aluminum strip 1 straightening has been cleaned and batched, utilize aluminium strip or steel band 3 to roll up 2 inner core 4 axial direction dues along aluminium and aluminium is rolled up outer ring fixed.
The present embodiment reduces the method for aluminum anneal defect, by adopting the mode of two ends welding, the aluminum strip that material tail takes off the aluminum strip after band and outmost turns is welded and fixed, the capable isolation can be involved in by coiling tension is unstable and coiling tension smaller portions and coiling tension normal segments aluminium, effectively can prevent aluminum strip from welding the loose layer problem of the aluminium volume within the number of plies, thus solve that the annealing produced due to loose layer is sticky hinders defect.In addition, by axially beating steel band, aluminium volume after annealing, it contacts maximum forced position with steel band be band two edge, and aluminum strip needs trimming when manufacturing a finished product, even if two edge occur that steel band ankle injury also can be cut away by as slitter edge, the quality of product can not be affected.
The above embodiment is only that protection scope of the present invention is not limited thereto in order to absolutely prove the preferred embodiment that the present invention lifts.The equivalent alternative or conversion that those skilled in the art do on basis of the present invention, all within protection scope of the present invention.Protection scope of the present invention is as the criterion with claims.
