In the production of double sheet foil, aluminum foil rolling sub roughing, intermediate rolling, finishing three processes, from a process point of view, can generally be divided from the strip thickness, the points system is generally thicker than exports or equal to 0.05mm for the roughing, exit thickness between 0.013 to 0.05 of the rolling, the thickness of less than 0.013mm leaflets export finished products and finished double-rolling to finishing.

Features roughing rolling and aluminum strip similar to control the thickness of the rolling force and rely mainly on post-tension, the thickness of the rough rolling processing rate is very small, which is completely different from the characteristics of the rolling rolling aluminum strip, with aluminum foil rolling particularity, which is characterized by the following main aspects:

Aluminum rolling.

For thin aluminum strip mainly rely on the rolling force, and therefore the thickness of the automatic control mode is constant roll gap control mode AGC body, even rolling force change at any time adjust the roll gap to maintain a certain value of the roll seam thickness can be obtained consistent plate and strip.

ARB

For thickness less than 0.012mm (thickness size and the work roll diameter related) of thin aluminum foil, since the elastic flattening roll, rolling with a single method is very difficult, so the use of double-rolling method, namely the two middle with foil oil, then combined rolling process (also known as ARB).

Speed effects

Aluminum foil rolling process, with the rise of the thickness of the foil-rolling system and thinning phenomenon known as speed effect. For speed effect mechanism yet to be explained in-depth study
