A cold-rolled sheet manufacturing process

Abstract

The invention relates to a cold-rolled plate manufacturing process. A bottom plate, a conveying device and a laminating device are included, the conveying device is arranged at the upper end of the bottom plate, the laminating device is arranged above the conveying device, and the laminating device is arranged on the bottom plate. The cold-rolled plate manufacturing process can solve the problemsthat existing cold-rolled plates are usually stacked in a direct stacking mode after rolling, however, in the stacking process of the plates, scratches on the surfaces of the plates easily occur due to mutual friction between the plates, and the surface quality of the plates is influenced; and at the same time, during laminating protection of the existing cold-rolled plates, the film attaching effect is poor, films are prone to falling off, bubbles exist between the films and the cold-rolled plates after attachment, and the subsequent use of the plates is not facilitated.

Description

technical field [0001] The invention relates to the field of cold-rolled sheet production, in particular to a cold-rolled sheet manufacturing process. Background technique [0002] Cold-rolled sheet has good performance, that is, through cold-rolling, cold-rolled strip and steel sheet with thinner thickness and higher precision can be obtained, with high flatness, high surface finish, clean and bright surface of cold-rolled sheet, and easy for coating Processing, many varieties, wide application, high stamping performance, no aging, low yield point, so cold-rolled sheet has a wide range of uses, mainly used in automobiles, printed iron drums, construction, building materials, bicycles and other industries. At the same time, it is also the best choice for the production of organic coated steel sheets. [0003] The existing cold-rolled sheets usually have the following defects in the manufacturing process: 1. After the existing cold-rolled sheets are rolled, they are usually ...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the problem that the existing cold-rolled plates are usually stacked directly after rolling. However, during the stacking process, the friction between the plates may easily cause scratches on the surface of the plates and affect the surface quality of the plates. At the same time, when the existing cold-rolled sheet is coated with a protective film, the bonding effect of the film is poor, and the film is prone to fall off, and there are air bubbles between the film and the cold-rolled sheet after bonding, which is not conducive to the subsequent use of the sheet.
