Progress of aluminum foil production technology

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 progress, the so-called electrical equipment upgrade is the control system upgrade. Plate shape instrument, the thickness gauge is with the digital control technology progress and progress. Not much change. Formers are more commonly adopted, performance is more stable, cost is cheaper. In fact, it is difficult to find the difference between the mill 20 years ago and the current mill. VC rolls are increasingly being used on wide foil mills. Cost more and more cheap.

Second, the progress of smelting technology, the application of new smelting technology to improve the inherent quality of aluminum, in particular, in addition to hydrogen and impurities, electromagnetic stirring and other new technologies are widely used, aluminum grain size, hydrogen content can be controlled in the very Stable level. Progress in raw materials makes the production of 6 microns, 5 microns, or even 4 microns of aluminum foil possible. Aluminum foil thickness depends entirely on the quality of raw materials, the last century 80's 7 microns, 90 years 6 microns, to the present 5 microns. Aluminum foil production technology is no different. The difference is that production is more proficient.

Aluminum foil production thickness from 7 microns to 5 microns, width from 1 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 progresses with the progress of society, there is no essential change. This and rolling, rolling the same as there is no essential difference. More prominent progress, that is the progress of raw materials, in particular, is a rolling mill production technology is a revolutionary progress. It reduces the cost of aluminum foil production, as the aluminum foil blank has its unique advantages.
