ROLLING METHOD FOR WIDE METAL STRIP FOIL

WIPO Patent Application WO/2022/217717

A1

A rolling method for wide metal strip foil. A rolling mill provided with working rollers of unequal diameters is used, and the roller diameter of one working roller of the rolling mill is greater than the roller diameter of the other working roller; during rolling, the linear speeds of roller faces of the two working rollers (1,2) are the same, metal strip foil (5) is wrapped on the roller face of one working roller to form a wrapping arc at an inlet side or an outlet side of a roller gap formed by the two working rollers, and the tension is uniformly distributed on the cross section of the wrapping arc by means of the back support of the working roller on the metal strip foil. By means of the method, the rolling mill provided with the working rollers of unequal diameters is used, which is beneficial for thinning strip foil and obtaining a better plate shape. In addition, by means of the method, the strip foil forms a wrapping arc on the working roller, and by means of the back support of the working roller on the strip foil, the front tension is uniformly distributed on the cross section of the wrapping arc at the inlet side, thereby achieving uniform-tension rolling of the strip foil, and breaking through the bottleneck of the development of a strip foil into a wider, thinner and more ideal plate shape being restricted, thereby solving the technical problem in the industry.
