Processing method.
Background technology
Specular aluminium is using quality control on the surface as the specialities of core in aluminium fabricated product, by its product handling system mode
Difference, can using rough segmentation as oxidation plate and it is non-oxide use plate, in the beginning of this century, the preparation process of anodic oxidation specular aluminium,
Mechanical polishing normal direction rolling upgrading is broken away from, and is succeeded first in Germany's peace aluminium and SUMITOMO CHEMICAL；The minute surface of the country of China
Aluminium processes the industrial chain for initially forming completion in 2010, but so far, and product concentrates on non-oxide 1100,1060 productions
On product and the low-end products such as 1070,1080 of oxidation, Zhejiang and the Henan for representing domestic specular aluminium processing highest level are related
Unit has made good try and breakthrough being with hot rolling in basic 1070 and 1080 mirror finish, but to representing
The aluminium purity of mirror board high-end level is achieved no breakthrough in 1085 or more oxidation with plate.
Invention content
The object of the present invention is to based on the single chassis unidirectional type cold-rolling mill that the country generally uses, one kind is provided
The Cold-forming process of 1090 minute surface woollens is provided for specular aluminium rolling, it is ensured that minute surface woollen fully meets mirror finish and sun
The needs of pole oxidation.
In order to solve the above technical problem, the present invention provides the following technical solutions：
A kind of Cold-forming process providing 1090 minute surface woollens for specular aluminium rolling, steps are as follows：
（1）First time cold rolling：1090 specular aluminium hot rolling blanks carry out cold rolling, general working rate 60~70%, wherein first
Secondary working modulus≤35%, with oil cleaning after cold rolling；
（2）Intermediate annealing：It is principle to passing through step using perfect recrystallization（1）The blank of processing is annealed；
（3）Second of cold rolling：By step（2）The blank of processing carries out cold rolling, and head pass reduction is 45~50%, it
Afterwards, continue to roll by single pass working modulus≤12%, general working rate 55~60%；
（4）By step（3）After processing, trimming, cleaning, straightening obtain 1090 minute surface woollens.
Preferably, step（1）The working roll for the use of surface roughness being 0.46~0.50 μm carries out cold rolling.
Preferably, step（1）The first time pass reduction is 33~35%.
Preferably, step（2）Annealing temperature be 330 DEG C, annealing soaking time be 8h.
Preferably, step（3）The working roll for the use of surface roughness being 0.30~0.40 μm carries out cold rolling.
Preferably, in step（3）In, after completing head passes, continue to roll by single pass working modulus 10~12%, always
Working modulus 55~60%.
Brightness after being aoxidized with minute surface（Containing mirror-reflection and diffusing reflection）And uniformity（Mainly aoxidize front and back material
Line, also compared with shading）For core, and the performance and surface features of minute surface woollen, woollen minute surface can be rolled and anode oxidation process
Product result tremendous influence acts on, and wherein process is cold worked mainly following aspects to woollen quality product in minute surface woollen
It directly affects：
1）Minute surface roughness and surface cleaning
Minute surface woollen, is one of the core elements that control this systems of 1090 specular aluminiums, the surface uniformity and spatter property of minute surface woollen,
It is the basis of diffusing reflection rate and aberration after influencing specular aluminium oxidation；And the roughness of working roll and clean twice, to work is cold worked
The surface cleaning of sequence minute surface woollen plays a decisive role.
2）The specific aim of specific pass reduction controls
Specific aim control to specific pass reduction is one of the core control point in the cold working of minute surface woollen, especially
It is second of slubbing being cold worked time that the slubbing time of cold working for the first time is stepped back in, it will be to the surface cleaning of minute surface woollen
It causes to directly affect with uniformity, and to show in the weight of the height of diffusing reflection rate and low temperature directly after mirror finish
Come.
3）Intermediate annealing process and woollen Properties Control
The intermediate annealing process of woollen is the middle direct shadow of annealing process where the core of entire minute surface woollen cold working process
The aberration and reflectivity after woollen mirror finish are rung, and entire woollen processing technology carries out technological balance with mirror finishing process
When most crucial factor.
The present invention carries out minute surface woollen production using the domestic single chassis unidirectional type cold-rolling mill generally used, is suitable for work
Industry mass production, production cost is low, and product disclosure satisfy that the cold rolling of all kinds of high-purity minute surface woollens, and practicability is extensive,
Production and control difficulty and at low cost, product competitiveness in the market is apparent, remarkable in economical benefits.This technique is suitable for 1090 minute surface hairs
The cold working of material is applied equally to the woollen cold working of 1080,1085 specular aluminiums of same purposes.
Specific implementation mode

In the description and interpretation present invention, it is not intended to limit the present invention.
Embodiment 1 is for processing 1090 minute surface woollens of 1.2mm × 1270mm H16
Supplied materials uses 1090 specular aluminium hot rolling blank of 7.5mm × 1310mm F states, and equipment can not using common single chassis
Inverse formula cold-rolling mill.
（1）First time cold rolling：The working roll for the use of surface roughness being 0.46~0.50 μm carries out cold rolling, each road to blank
Design is as follows：7.5mm → 5.0mm → 2.7mm, is cold-rolled to 2.7mm（The purpose for being rolled into 2.7mm is ensured after intermediate annealing
Second of cold-rolled process in, absolute draft amount meets the intensity of minute surface woollen finished product 1.2mm and elongation percentage meets technique and wants
It asks）, first time cold rolling finished product with oil cleaning complete surface rolling oil, aluminium powder cleaning, be completed at the same time upper and lower surface exchange so that
The upper surface of hot rolling blank（Namely face cleaning）Surface is used for final finished（Surface quality is optimal at this time）.
（2）Intermediate annealing：Using perfect recrystallization as principle, to passing through step（1）The blank of processing is made annealing treatment, and is moved back
Fiery temperature is 330 DEG C, and annealing soaking time is 8h.
（3）Second of cold rolling：After the working roll for the use of surface roughness being 0.30~0.40 μm is to intermediate annealing process
Blank carries out cold rolling, and each road design is as follows：2.7mm → 1.35mm → 1.2mm, wherein the first passages of 2.7mm → 1.35mm are greatly
The purpose of work rate realizes the violent broken and microstructure homogenization of the crystal grain of interior tissue, the small processing of the second passages of 1.35mm → 1.2mm
