Repeat-rolling is carried out in milling train, is implemented room temperature cooling after the completion of rolling, blank after cooling is subjected to Double Milling；It e, will step
The dispensing that Double Milling is completed in rapid d carries out breaking down；F, the blank that breaking down is completed in step e is put into and is moved back into annealing furnace
Fire is carried out room temperature cooling after completing annealing；G, the blank that annealing is completed in step f is subjected to secondary rolling；H, by step g
The middle blank for completing secondary rolling carries out double annealing；I, the blank that double annealing is completed in step h is subjected to preliminary pickling；j、
The blank that preliminary pickling is completed in step i is rolled three times, then the blank rolled three times is annealed again, is completed
Pickling is carried out after annealing；K, the blank that pickling is completed in step j is subjected to four rollings, forms banding finished product；It l, will be in step k
Banding finished product carry out degreasing pickling, then its surface is passivated and dried.
Using above-mentioned technical proposal, by four rollings, make blank gradually thinning, and respectively to blank after each rolling process
It anneals, reduces hardness, convenient for rolling；And by the two-sided implementation Double Milling to blank, the flat of blank surface is ensured with this
Whole degree, while also ensure the quality of the brass band processed, it is allowed to can be used in highly sophisticated device using.
The present invention is further arranged to：The thickness of blank after tentatively being rolled in step e is 3.0mm -3.5mm；Step g
In secondary rolling blank thickness for 1.0mm -1.7mm, while the flash notch at its both ends is wiped out.
0.3mm -0.5mm is removed on the surface of blank per facing cut during Double Milling in step d；Annealing furnace in the step f passes through
3h -4h rises to 500 DEG C -580 DEG C heat preservations, and naturally cooling to 80 DEG C -90 DEG C after heat preservation 3h -4h comes out of the stove.
The blank for completing to roll three times in step j enters in annealing furnace rises to 400 DEG C -460 DEG C by 3h -3.5h, protects
70 DEG C -80 DEG C are naturally cooled to after warm 3h -4h to come out of the stove.
Using above-mentioned technical proposal, above-mentioned thickness is rolling to successively, makes blank thinning in proper order, by constantly annealing and rolling
System, you can ensure the surface smoothness of brass band, while the toughness of the brass band and plasticity can be made more preferable, be not easily broken and grind
Damage.
Specific embodiment
