Description
Technical Field
The invention belongs to the field of processing of aluminum and aluminum alloy non-ferrous metal materials, and particularly relates to a processing method of 1050 aluminum alloy medicine cover materials.
Background
At present, along with the rapid development of the bio-pharmaceutical industry, the standards of pharmaceutical packaging design of pharmaceutical manufacturers are getting higher and higher, and an oral liquid aluminum medicine cover serving as a medicine packaging material matched with an oral liquid glass bottle is one of main components of medicine packaging of antibiotics and the like, has excellent sealing property, attractiveness and flexibility, and is widely applied to the bio-pharmaceutical industry. Nowadays, China is continuously introducing and upgrading machinery and materials in the aspect of biological medicine, and industrial production of aluminum medicine caps shows a new situation.
A typical technical route for 1050 aluminum alloy aluminum pharmaceutical cover stock is as follows: smelting and casting → ingot sawing → ingot surface milling → ingot homogenizing and heating → hot rolling → cold rolling → finishing, cleaning and trimming → intermediate annealing → cold rolling → finished product cleaning and trimming and straightening → finished product inspection.

The tensile strength and the earing rate can not meet the special requirements of customers on the performance of 1050 aluminum alloy aluminum medicine cover materials.
Disclosure of Invention
The invention aims to provide a processing method of 1050 aluminum alloy pharmaceutical cover materials, which can improve the tensile strength of 1050 aluminum alloy pharmaceutical cover materials, reduce the earing rate and meet the requirements of customers on the performance of the pharmaceutical cover materials by adjusting the cold rolling processing rate, adjusting the intermediate annealing process and the like.
In order to achieve the purpose, the invention adopts the technical scheme that: a1050 aluminum alloy chemical cover material processing method comprises the steps of heating, hot rolling, cold rolling, cleaning and trimming 1050 aluminum alloy ingots after saw cutting and surface milling, and inspecting finished products to obtain chemical cover material products; carrying out intermediate annealing process treatment in the cold rolling process, wherein the intermediate annealing process comprises two annealing processes, the first annealing process is carried out at the temperature of 455-465 ℃ for 6.5-7.5 h, and the second annealing process is carried out at the temperature of 415-425 ℃ for 4.5-5.5 h; the final rolling temperature of the hot rolling is 295-310 ℃, and the cold rolling pass processing rate after the intermediate annealing process is 80-85%.
The temperature of the first-stage annealing is 458-465 ℃, and the time is 7 hours; the temperature of the second-stage annealing is 418-425 ℃, and the time is 5 h.
The cold rolling pass reduction rate is 81-84%.
The heating treatment is homogenizing heating at 560 ℃ and 580 ℃ for 22-26 hours.
The temperature of the homogenization heating is 565-575 ℃, and the time is 23-24 h.
The 1050 aluminum alloy cast ingot adopted by sawing is a cast ingot produced by a semi-continuous water cooling casting method.
The invention has the beneficial effects that: the processing method provided by the invention fully utilizes the alloy characteristics of 1050 aluminum alloy, controls the final rolling temperature of the hot-rolled coil by optimizing the ingot casting homogenization heating process of 1050 aluminum alloy, and ensures that the internal recrystallization (cubic) texture of the hot-rolled coil accounts for more than 70%; and regulating and controlling the processing rate of the cold rolling pass of the intermediate annealing, and combining the influence of the intermediate annealing on the internal texture of the material to produce the 1050 aluminum alloy pharmaceutical cover material with high tensile strength and low earing rate, thereby meeting the special requirements of customers on the material.
The principle analysis of the method adopted by the invention is as follows:
1. and regulating and controlling the final rolling temperature of the hot rolled coil. The finish rolling temperature is an important factor influencing the proportion of the internal texture of the material, the finish rolling temperature is low, and the internal texture of the hot rolled coil is an obvious rolling texture; when the finish rolling temperature is normal, the internal structure of the hot rolled coil contains a certain amount of cubic texture, and a part of rolling processing texture exists at the same time; when the finishing rolling temperature is high, the cubic texture occupation ratio of the internal texture of the hot rolled coil is more than that of the rolling texture. The cubic texture of the hot rolled coil with the cubic texture occupying ratio more than that of the rolled texture is converted into other textures in the subsequent cold rolling process, and the retained trace cubic texture becomes a cubic texture nucleation point. After subsequent intermediate annealing, the cubic texture nucleation points promote the growth of the cubic texture and balance with the cold rolling texture, and the final finished product can obtain ideal earing rate. Therefore, if the finishing temperature of the hot-rolled coil is too high, the cubic texture proportion is too high, which leads to the material having too high cubic texture content after intermediate annealing, and 0/90-degree direction earing is formed. If the finishing temperature of the hot-rolled coil is too low, the proportion of the rolling texture in the material is too high, so that the rolling texture content of the material after intermediate annealing is too high, and 45-degree direction earing is formed. Based on the above, the finishing rolling temperature provided by the invention is a range capable of meeting the product performance requirements under the condition of comprehensively considering the characteristics of 1050 aluminum alloy materials, the temperature control of heating treatment and the intermediate annealing process.
2. And adjusting the cold rolling pass machining rate after intermediate annealing. At present, the cold rolling pass working rate of 1050 aluminum alloy is about 57%, but the tensile strength can not meet the requirement of a chemical cover material. In contrast, the larger the cold rolling pass machining rate after intermediate annealing of the aluminum alloy material is, the more internal energy storage is increased, the higher the tensile strength of the material is shown, but when the pass machining rate is too high, the higher the work hardening degree of the material is, and the pine twig pattern defect on the surface can appear when the material is continuously rolled due to the capability of a cold finishing mill, so that the surface quality of the product is influenced; in the severe case, the rolling cannot be continued. Therefore, the cold rolling pass working rate provided by the invention can improve the tensile property of the material, avoid the surface defects in the rolling process and increase the proportion of the rolling texture so as to be beneficial to obtaining the ideal earing rate.
3. And adjusting the intermediate annealing process. The key point of the invention is that a high-temperature short-time intermediate annealing process method is adopted, the material reaches the required temperature in the shortest possible time by a higher-temperature rapid heating method, and simultaneously the formation of a large amount of cubic textures is facilitated, the 80-85% large processing rate of cold rolling after intermediate annealing is beneficial to the formation of a large amount of rolling textures, the cubic textures and the rolling textures can reach balance, and further the ideal earing rate (within 2%) is obtained. The grains in the annealed material are uniform and fine, and the second phase and the like can be dissolved more fully, so that an ideal annealed structure is obtained. At present, when the conventional medicine cover material is prepared, a relatively low-temperature long-time annealing process is generally adopted, although the material can be subjected to heat treatment to be in a complete recrystallization state, crystal grains in the material are not fine and uniform enough, the number of cubic textures is not enough, the material cannot be balanced with a rolled texture after annealing, and finally the material has poor anisotropy and the earing rate cannot be ensured.
4. And optimizing the ingot casting homogenization heating process. After semi-continuous water-cooling casting, the 1050 aluminum alloy ingot has dendritic crystal segregation in different degrees, which causes non-uniformity of components and structures. The ingot is heated uniformly in order to eliminate defects of ingot components and uneven structure generated during casting. And with reference to the heating temperature and the heating time of 520 ℃ and 16h of the normal 1-series aluminum alloy ingot, because the temperature is low, the external power is not enough to dissolve precipitated phases, the congenital defect can occur, so that the cold-rolled finished product has relatively uneven structure, large lug making rate dispersion and poor stability. The adoption of the homogenization heating of the invention can fully dissolve the precipitated phase in the internal structure of the cast ingot, the internal structure of the finished product is uniform and consistent after cold rolling, the material has better anisotropy, and the earing rate can be further controlled.
