2017/4/17 15:34:17
In the aluminum foil production enterprises, the focus has been on how to double the overall performance of aluminum foil to enhance, so that the product level is improved. The past double aluminum foil alloy material is mainly 1235 alloy, the use of traditional production technology to produce the product, its various aspects of the performance can not fully meet the actual requirements. Therefore, based on the good performance of pinhole, surface quality and mechanical properties of 8006 alloy and 8011 alloy in air-conditioning foil and 8006A alloy, it is proposed to use 8006 alloy and 8011 alloy to produce 0.0065 Millimeter-level double-zero aluminum foil production process. After the corresponding theoretical research and a period of time test test, proved the actual effect is more ideal.
First, the test program
In the course of the test, the first 1235 alloy and 8011 alloy related test, and then comprehensive test results and user feedback, the 8006 alloy double zero foil test. For the 030065x787 mm product specifications, the use of different annealing process for each alloy and experimental study. The effect of intermediate annealing, homogenization annealing, conventional intermediate annealing and other processes on the performance of aluminum foil products was mainly improved between 1235 alloy and 8011 alloy. Based on the test of 1235 alloy and 8011 alloy double zero aluminum foil production process, the work hardening and annealing process of 8006 alloy were studied, and the pinhole, surface and performance of industrial annealed materials were studied.
(A) different alloy test program
1.1235 alloy test program
The first process is 7.5 mm cast steel plate, homogenized annealing cold rolling 3.8 mm, intermediate annealing cold rolling 0.4 mm, then rolling aluminum foil, normal process annealing combined 0.0065 mm. The second process is a 7.5 mm cast roll, which is cold rolled by 0.8 mm in the middle, then cold rolled and rolled aluminum foil, normal process annealed 0.0065 mm.
2.8011 alloy test program
The first process is 7.5 mm cast steel plate, the middle annealing is cold rolled 0.8 mm, then rolled aluminum foil, the normal process annealing double 0.0065 mm The second process is 7.5 mm cast plate, uniform The annealing was carried out by cold rolling of 3.8 mm, intermediate annealing followed by cold rolling of 0.8 mm, followed by rolling of aluminum foil, normal process annealing combined 0.0065 mm.
3.8006 alloy test program
The first process is homogenized annealing of 7.5 mm standing plate, 0.4 mm cold rolling in the middle annealing, then rolling aluminum foil, double 0.0065 mm, then the cutting and annealing experiments, and then the industrial annealing experiment, Finally packed. The second process is homogeneous annealing of 7.5 mm cast slabs, intermediate annealing cold rolling 0.4 mm, then double 0.0065 mm, followed by slitting, finished annealing, and final packaging.
(B) Main inspection items and testing equipment
Starting from the aluminum foil wool, the mechanical properties of the road by the test, the processing of hardening curve drawing. The aluminum foil finished product, the brushing test, plate quality, surface quality, pinhole, mechanical properties of the test. Among them, the brushing test can be in the multi-layer aluminum foil roll material after the use of water and absorbent cotton; plate quality, surface quality can be directly observed; the use of standard pinhole pinhole detection: the use of electronic tensile testing machine Performance detection.
