Aluminum foil production technology and equipment of the latest developments

Aluminum foil production technology progress, mainly due to two aspects
The first is the progress of automatic control technology, computer applications, especially the application of digital technology, aluminum foil production equipment is the main content of the progress of the so-called electrical equipment upgrade is the main control system upgrade. Plate-shaped instrument, thickness gauges are with the progress of digital control technology and progress. Not much change. The shape meter is more commonly used, the performance is more stable, the cost is cheaper. In fact, it is very difficult for you to find the rolling mill 20 years ago and the current mill in the mechanical What is the obvious difference. VC rolls are increasingly being applied to wide aluminum foil mills. The cost is getting cheaper.
Followed by the progress of smelting technology, the application of new smelting technology to improve the inherent quality of aluminum, especially in addition to hydrogen removal, electromagnetic stirring and other new technologies are widely used, aluminum grain size, hydrogen content can be controlled in very Stable level. The progress of raw materials makes it possible to produce 6 microns, 5 microns, or even 4 micron aluminum foil. The thickness of the aluminum foil is entirely dependent on the quality of the raw material, 7 microns in the 1980s, 6 microns in the 1990s, and now 5 microns. There is no difference in the production technology of aluminum foil. The difference is that production is more skilled.
Aluminum foil thickness from 7 microns to 5 microns, width from 1 meter to 2.3 meters, rolling speed from 500 meters to 2000 meters there is no essential difference. In other words, aluminum foil production for nearly a hundred years is a gradual process, it progress with the progress of society, there is no essential changes. This is the same as rolling, rolling copper, there is no essential difference. More prominent progress, that is the progress of raw materials, especially casting and rolling production technology is a revolutionary progress. It reduces the cost of aluminum foil production, as aluminum foil blank has its unique advantages.
