The invention relates to the technical field of strip steel manufacturing, in particular to a cold-rolled strip steel manufacturing process. The process comprises the following steps: step 1, carrying out oil removal, rust removal and acid pickling on raw materials; 2, cold rolling is conducted on the raw materials through cold rolling equipment, and strip steel is obtained; 3, releasing the internal stress of the strip steel during cold rolling by using a manufacturing device, and cooling the strip steel; fourthly, the corners of the strip steel are cut and rolled, and manufactured cold-rolled strip steel is obtained; the manufacturing device comprises a rotating roller capable of rotating around the axis of the rotating roller, a plurality of protrusions evenly formed on the surface of the rotating roller and a base used for rotation of the rotating roller, a gear motor is installed on the base, and the rotating roller is driven by the gear motor to rotate. Non-uniformly distributed stress in the strip stee
