It is preferred that, the optimum thickness of the chromium plating roll chromium coating is 80-100um.Roll chromium coating thickness is to combine roll in itself
The finished product thickness of material characteristic, size and institute's calender roll mirror board is determined.It is the reduction of chromium coating blocked up tack, easy to fall off；
The excessively thin hardness reduction of chromium coating, easy damaged.
In such scheme, the percentage pass reduction of the 4-roller cold rolling mill is 30-50%.
In further technical scheme, the passes power of the chromium plating roll is 80-150t.
Further in technical scheme, keep not changing face rolling during the mirror roller rolling, the one side of minute surface all the time only with plate face
Contact.
By above-mentioned technical proposal, the aluminium provided and aluminium alloy mirror board of the invention, the processing method of band are directed in production process
Easy produced problem is improved, and chromium plating process is carried out to common roll surface, and chromium coating has very high hardness, and its hardness is most
Big reachable 1000HV, and chromium coating has preferable heat resistance.Under rolling temperature, its glossiness, hardness have no significant change,
The coefficient of friction of chromium coating is small, particularly dry friction coefficient, is minimum in all metals, so chromium coating has very well
Wearability, the aluminium powder amount produced in calender line is few, and the pollution to roll surface is small；Chromium coating has good chemistry steady simultaneously
It is qualitative, do not had an effect with ROLLING OIL, it is pollution-free to ROLLING OIL.
Compared with prior art, have the following advantages that：
1st, roll maintenance cost is reduced.The wear-resistant and antibody Monoclonal ability of chromium plating roller surface is strong, can avoid other in production process
The injury of roller system and plate face to roller surface, suppression roll surface roughness fall off rate, the mirror effect of long sustaining roller surface,
The usage cycles of roll are extended, roller surface maintenance cost is reduced.
2nd, production efficiency is improved.Due to reducing in production process because in the production disruption and production process caused by roller surface defect
Roll change number of times, substantially increase production efficiency.
3rd, aluminium sheet mirror-quality is lifted.The aluminium powder amount produced in the chromium plating roll operation of rolling is small and is not adhere on roll, easily rinses,
So that mirror board, the specular light brightness uniformity of volume, and otherness is small, batch is stable.
