Description
Technical field
The present invention relates to the technical field of the production technology of double-zero aluminum foil, the technique that especially a kind of casting-rolling method produces 8011A alloy double-zero aluminum foil.
Background technology
In known technical field, through developing rapidly of nearly more than two decades, the foil industry of China has been achieved for the achievement caught people's attention, and has become as the big aluminium foil manufacturing country of undisputed the first in the world. In numerous aluminium foil products, double zero foil is one of them part and parcel, owing to double zero foil production difficulty is big, with high content of technology, and added value of product is high, so the level of production of double zero foil represents the integral level that a national aluminium foil produces to a certain extent. At present at home, the production Technology of double zero foil is also ripe day by day, and increasing aluminium foil manufacturing enterprise can produce the high-grade double zero foil product of wide cut, great surface quality, low pin hole. In the past, the production of double zero foil mainly adopts fine aluminium series alloy to be main, is that alloy is for major alloy kind to produce double zero foil with 1235,1145 etc. 1. But in recent years, along with the raising of the development in market and production Technology level, adopting 8 is that the enterprise of contour alloy double zero foil gets more and more. High alloy double zero foil, because of the surface quality of its uniformity and excellent mechanical performance, more and more obtains the favor of domestic and international aluminium foil client. Adopting hot rolling technology to produce high alloy double zero foil, because structural homogenity is likely to be obtained sufficient guarantee, so having inborn advantage compared with casting and roll process, the high alloy double zero foil of current domestic a lot of producers also adopts hot rolling woollen to produce. Comparatively speaking, adopt casting and roll process to produce high alloy double zero foil, due to the restriction by manufacturing condition, it is easy to internal structural flaw occurs, cause the instability of product quality. This point currently also annoyings a lot of aluminium foil factory. How to adopt casting-rolling technology, produce high-quality alloying double zero foil, just become a pendulum problem in face of vast technologists.
8011A aluminium alloy: refer to that, according to the requirement in standard GB/T/T3190-2008, corresponding alloy designations is the aluminium alloy kind of 8011A, and its ferrum, silicone content are higher than pure aluminum alloy.And the double zero foil product produced at present both at home and abroad, major part is the alloys such as 1235,1145, and its fine aluminium content is far above 8011A alloy.
Double zero foil: the aluminium foil products of dinger thickness degree≤0.01mm, owing at aluminium foil production field, more double zero foil product thickness≤0.007mm, so the double zero foil described in this patent, also referring to the aluminium foil products of thickness≤0.007mm. The application of current this product is increasingly extensive, and production technology reaches its maturity. But adopt casting-rolling method to produce the double zero foil of 8011A alloy, also belong to pioneering at present at home. High alloy double zero foil, because of its good surface quality and excellent mechanical performance, is increasingly subject to the favor of high-end aluminium foil application market.
The application of double zero foil is mainly packaging industry, electron trade and tobacco business, such as tetra pak package, food Soft Roll, pharmaceutical pack, power capacitor, cigarette package etc. Double zero foil client domestic at present is mainly distributed on Pearl River Delta, Yangtze River Delta Area, Circum-Bohai Sea and the Northeast also client, and foreign customers is mainly European and American areas and the ground such as Southeast Asia, Japan. Products application is very extensive, and customer group is very huge. Along with the raising of expanding economy and living standards of the people, estimate quickly to increase further as the consumption figure of the aluminum per capita of the developing countries such as China, India. Therefore, double zero foil has very wide market prospect. At present, the production technology of double zero foil is mature on the whole, and product is domestic all can produce for major part. But some are high-end, the double zero foil product that technology content is higher, such as great surface quality, low pin hole, high performance double zero foil product, current production technology is also not as ripe, produce 8011A alloy double zero foil in particular by casting-rolling technology, substantially belong to blank at present at home.
Adopt casting-rolling method to produce 8011A alloy double-zero aluminum foil, from the angle analysis of technology, mainly have the following aspects:
1. due to the increase of ferrum, element silicon in metal, the control difficulty making interior tissue uniformity is big;
2. risen by melting point metal and solidify difficult impact, production process producing center segment and center-line segregation defect occurrence probability increases;
3. due to the increase of impurity element so that following process and grain size control difficulty increasing in heat treatment process;
4. significantly raised due to alloy strength so that the thinning difficulty of rolling process product increases.
For above several phenomenons, We conducted the conscientious analysis of causes, it is believed that mainly have following items reason:
1. its maximum feature of casting-rolling technology, it is simply that the solidification of aluminum liquid and roll forming simultaneously complete, nearly 700 DEG C of temperature of aluminum liquid before solidification. In this case, even if keeping high intensity of cooling, it is also difficult to realize heavy reduction rate rolling in moment. Particularly 8 is alloy, and owing to the iron content in its alloying component is high, it is bigger to the control difficulty of structural homogenity in strip casting process;
2. in casting production process, in the product band completed of final solidification, the phenomenon of the uneven superfluous compositions of concentration is occurred in that near central core, it is called intracrystalline or center-line segregation, this segregation mainly belongs to a kind of component segregation, the position of segregation occur, the content of its alloy part composition is significantly larger than normal standard-required. Producing heavy alloyed product, owing to its alloying component content is high, particularly Fe element and Si constituent content are apparently higher than 1235 alloys, and its product strength is high, and rolling difficulty is big, therefore, in process of production, it is easier to center-line segregation occur.And center-line segregation is one of double zero foil major reason pin hole occur. In production process, it is necessary to this phenomenon is caused enough attention, only this controlling factors is good, is only possible to and produces high-quality double zero foil with casting and roll process;
3. general 8 be alloy in casting production process, because its alloying component content is high, when Casting Rolled Sheet detect, it is found that it occurs that the situation of big crystal grain is little, its control difficulty will lower than pure aluminum alloy. But this brings a lot of problems also to the control of follow-up annealing operation simultaneously. In production process, producing 8 is that alloy this phenomenon often occurs, it is simply that when casting produces, detection grain size is one-level, but in subsequent anneal process, occurs as soon as serious Phenomena of Grain Growth. Particularly some high ferros, high manganese, this phenomenon becomes apparent from. If if this is because deal with improperly in follow-up annealing process, even if Casting Rolled Sheet grain size is controlled well, in subsequent process, still because of the impact of some alloying element, recrystallization process can be there is. If long for heat time heating time in follow-up intermediate annealing operation, also easily there is secondary recrystallization, i.e. recrystallization process, cause the situation that crystal grain is grown up further. The woollen of this surface quality, in follow-up production process, aluminium foil surface, especially the dark face of pairing aluminium foil there will be obviously fibrous tissue, and surface quality can be severely impacted, simultaneously, the horizontal mechanical performance of product also can worsen, and product shows as obvious anisotropy;
4. owing to 8 is that alloy product intensity is higher, if casting and cold-rolling process controlling improper, the production difficulty of subsequent process can be made to strengthen. The situations such as especially in the operation of rolling of aluminium foil operation, arising that roll-force raises, rolling pass increases, and product is difficult to thinning, mill speed substantially quickening. In this case, in process of rolling aluminum foil, it is necessary for constantly adjusting various technological parameter, such as gloss level of roll, convexity, the proportioning of rolling oil additives, in production process, operator are in order to reach target thickness, are also forced to adjust the rolling technological parameters such as rolling oil temperature, front and back tension force, mill speed. Also can frequently there is broken belt because being difficult to thinning in product, have impact on the normal of aluminum foil rolling to produce and production efficiency, simultaneously, this continuous improper adjustment, also stablizing of aluminum foil rolling process system it is unfavorable for, the stability of whole production process can be destroyed, the production of other kind is also brought along adverse effect. So, adopting 8 is alloy production double zero foil, it is necessary to solve product strength high, it is difficult to thinning problem.
