Short-process rolling method for cold-rolled 5182 alloy tank cover material

The invention provides a short-process rolling method for a cold-rolled 5182 alloy tank cover material, and solves the problems that cold rolling is divided into six passes, and each pass is drifted, so that in the rolling process, the consumed time is long, the working efficiency is low, the number of times on a machine is increased and the probability of generation of bumping defects is also increased. The method comprises the following steps of: 1, single-stand cogging, wherein the thickness of a plate subjected to single-stand cold rolling is converted from 2.8 mm to 1.38 mm; 2, double-stand edge trimming, wherein the thickness of the plate subjected to double-stand cold rolling is converted from 1.38 mm to 0.76 mm and then converted to 0.46 mm, then the plate subjected to cold rolling is cooled to the rolling temperature of 60 DEG C and then is transferred to a finishing edge trimmer, and the edges of the plate are cut by 20 mm separately; 3, single-stand cold rolling, wherein the thickness of the plate
