as shown in fig. 3, the present application has an increased number of front and rear S-roll sets as compared with a general rolling mill. And after the aluminum strip passes through the front S roller set and the rear S roller set, the front S roller set 2, the main rolling mill 3 and the rear S roller set 4 form a splayed shape with an included angle of 60 degrees. Therefore, the wrap angle between the aluminum strip and the front and rear outlet turning carrier rollers of the main rolling mill 3 is larger, the stability of the aluminum strip in rolling the mirror surface is improved, and the shake is reduced to ensure the stability of the mirror surface effect. In addition, the front S roller set and the rear S roller set can ensure that the aluminum strip passes between the mirror surface rollers of the main rolling mill straightly and does not slide towards the left side and the right side by adjusting the traction tension of the motors of the front S roller set and the rear S roller set. The traditional rolling mill can only provide tension by the uncoiler 1 and the coiler 5 because of no front and rear S roller sets, but because the surface of an aluminum strip after passing through a rolling mirror is very fragile, if the tension is too large, the surface of the aluminum plate can be bruised, and the aluminum plate can be scratched like a needle.

Solves the problem of contusion of the mirror rolling surface.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
