Description
Technical field
The invention belongs to aluminium alloy manufacture field, and in particular to a kind of anodic oxidation granule surface contral work of soft state aluminium alloy
Skill.
Background technology
1090 aluminium alloys of anodic oxidation, belong to international with commercial-purity aluminium at present（Aluminium purity is >=99.90%, is not typically surpassed
Cross 99.93%）For base material, it is widely used in the alloy product of the highest ranking in illumination and decoration field, by its use state, and
It is divided into the soft state of anodic oxidation（State containing medium-soft）With hard state product, its Anodic Oxidation is with 1090 soft states for product and anodic oxidation
（State containing medium-soft）Product, so that Mingguang City's type is reflective 1090 reflectors are used（The country is also referred to as reflection shield）For represent, product with high brightness,
With the characteristics of high forming ability, it is widely used in indoor and outdoor and field is shone in traffic；And anodic oxidation is with 1090 hard state products, then with
1090 mirror boards are representative（1085 mirror boards that Germany's peace aluminium is used, are that Ti contents control model beyond BSEN 573-3-2009
Product after enclosing, its mother metal aluminium purity ＞ 99.90%, so the category of 1090 aluminium alloys is included in the industry）, product has
Quality characteristic of the high brightness without shading, is widely used in the fields such as high-end traffic, decoration, indoor and outdoor lighting.It is domestic at present to hand over
The alloy product in logical illumination and decoration field, concentrates on 1070 and 1050,1060 etc. grade aluminium alloys of low and middle-end, and reflecting rate exists
60～70%, the processing method of such product, except DC（Hot rolling）Outside processing mode, or even also CC（Casting is rolled）Roll
The method production of system, the disappearance of this core technology and the disorderly competition of domestic market, not only result in domestic enterprise's exploitation
The investment risk of 1090 high-end anodic oxidation materials is raised, while also causing China to develop the paces of anodic oxidation product high-endization
Stagnation.
The anodic oxidation concrete processing technology of 1090 aluminium alloys, is slightly different with the difference of its product purpose, but,
It finally has to pass through anodised technological process requirement and essentially identical product quality demand, determines that anodic oxidation is used
The typical technology path of 1090 alloy products is as follows：
1）, the anodic oxidation aluminium alloy typical technology route of hard state 1090
The anodic oxidation aluminium alloy of hard state 1090, its main work flow is needed through the casting of plate ingot, the sawing of plate ingot and milling face, plate
Ingot is homogenized and hot-working, plate ingot cold working, sheet material thick material cleaning, sheet material intermediate heat-treatment, sheet material mirror finish, sheet material straightening
With trimming, sheet material cleaning and overlay film, sheet material anodic oxidation, ten key links are waited.But for technical difficulty, before mirror finish
The four processes such as the casting of plate ingot, plate ingot hot-working, the cold working of plate ingot and intermediate heat-treatment, be the core technology institute of whole industry
, also, this four processes also has the internal relation of mutual check and balance, specifically, the hard state of anodic oxidation
The typical technology route of 1090 products is as follows：
Casting → → plate ingot the sawing of plate ingot and milling face → → plate ingot homogenization → → hot rolling → → cold rolling → → intermediate annealing → →
Minute surface rolling → → straightening trimming → → cleaning overlay film → → anodic oxidation → → finished product
2）, the anodic oxidation aluminium alloy typical technology route of soft state 1090
The anodic oxidation alloy product of soft state 1090, because there is notable difference with hard state product in purposes usage, so in processing
A certain degree of difference is there is also in flow process, most typical work flow is mainly included：The casting of plate ingot, the sawing of plate ingot and milling face,
Plate ingot is homogenized opens plate, plate stamping shaping, anodic oxygen with hot-working, plate ingot cold working, coiled material cleaning, coil annealing, coiled material
The nine big links such as change, the technological core of whole industry still concentrates on the casting of plate ingot, plate ingot homogenization and hot-working, plate ingot table
Several core links such as face process, specifically, anodic oxidation is as follows with the typical technology route of the alloy product of soft state 1090：
Casting → → plate ingot the sawing of plate ingot and milling face → → plate ingot homogenization → → hot rolling → → cold rolling → → cleaning → → annealing
→ → open plate → → punching press（Or spinning）Shaping → → anodic oxidation → → finished product.
1090 alloy products of anodic oxidation, are respectively high reflecting rates with two very clear and definite technical indicators
（It is referred to as brightness in the industry, while being characterized with mutually contradictory specular reflectivity and diffusing reflection rate）It is anti-without affecting with after anodic oxidation
The shading of optical uniformity.The factor of reflecting rate is affected, the oxidation being concentrated mainly on after plate ingot grain size, plate ingot aluminium purity, oxidation
Five aspects such as the interface state control of film uniformity and dense degree, woollen surface uniformity and uniformity and mirror finish；
And the principal element of impact shading defect, then when concentrating on surface with interface uniformity, woollen surface cleaning and mirror finish
Three aspects such as interface state control accuracy, and interface state control accuracy during mirror finish concentrates on absolute draft again
Amount control, plate form control and lubricating status control, these three influence each other and mutually in the technical indicator of balance.
Based on exemplary process flow process of the anodic oxidation with 1090 products, the principal element of product quality is affected
Following aspects：
1）Plate ingot casts
1090 aluminium alloys belong to commercial-purity aluminium series of products, and needs solve the aluminium purity control for mutually liquidating when plate ingot casts simultaneously
System controls two key problems with grain size.Aluminium Pureness control is exactly that casting process cleans control, to prevent other as far as possible
Constituent element is introduced as principle and carries out process cleans control, and plate ingot grain size is controlled, and must reach the water product of one-level, and objective
Substantial amounts of grain refiner is needed to participate in the casting of plate ingot in sight, and, product finally needs to carry out anodised product manufacturing
Feature, causes grain refiner while participating in grain size and controlling again, the B element in strict control panel ingot, so as to can only
The lean B grain refiners for selecting grain refining effect weaker, the usage amount for increasing grain refiner is needed so as to client is upper again
To ensure plate ingot grain size number, cause the increase of the content of Ti, aluminium purity is reduced again in turn, so as to need aluminium purity more
High fine aluminum liquid come enter andante ingot casting（1090 U.S. sub- aluminium alloys of Hong Kong of most significant end in the world, be exactly using price very
Expensive aluminium purity be 99.95% industrial rafifinal casting 1090 aluminium alloy plate ingots, it is domestic then do not develop completely on an equal basis
The plate ingot of quality level）, sum it up, core technology of this product in terms of casting, is how to the greatest extent may be used using aluminium purity
The low aluminium liquid of energy, by technology controlling and process and balance, obtains the 1090 aluminium alloy plate ingots that grain size is one-level, so as to low cost
Commercial-purity aluminium（99.90%）Carry out cast sheet ingot, and reach external using industrial rafifinal（99.95%）The quality water of cast sheet ingot
It is flat.
2）Hot-working and cold worked surface control with interface uniformity and spatter property
1090 alloy product anodic oxidation purposes surfaces and the realization of interface particular/special requirement, are by hot-working work and cold working
Realize that this requirement is needed in theory by arc length with based on method, and with hot-working interface is realized with interface hereditary effect in surface
Uniformly turn to target design hot rolling technology, realize that surface conformance is technological design core with cold working, and by hot-working with
Cold worked technological balance, completes interface and Surface uniformization and uniformity, and the such as U.S. Asia industry of external colleague by heat
The multi-frame continuous hot-rolling mill of manufacturing procedure（Malaysian U.S. Asia industry is " 1+3 " continuous hot-rolling mill）To realize this special process work(
Energy.
3）High-elongation demand and sheet material organizational controls（Heat treatment）
The interface uniformity of rafifinal system product derives from structural homogenity, but high pure lines product in casting because of aluminium purity very
Height, need to strictly control the use of grain refiner during casting, the structural homogenity of high pure lines product is most rambunctious.Anodic oxygen
Change with the organizational controls core of 1090 alloy products, concentrate on plate ingot grain size control, hot worked tissue reformation and timeliness,
Cold worked Interface Control and finished product recrystallization annealing aspect, and this completes hot worked plate ingot homogenizing annealing process and
Core content in terms of the design of hot finish to gauge aging temp and cold rolling finished product annealing process and balance.
