Embodiment Construction
[0035] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0036] Such as Figure 1 to Figure 5 Shown, a kind of cold-rolled sheet manufacturing process comprises the following steps:
[0037] S1. Plate cleaning: manually clean the residual dust and impurity particles on the surface of the plate;
[0038] S2. Surface treatment: remove the grease, iron oxide scale and rust on the surface of the plate by pickling, and then remove the residual acid by water washing;
[0039] S3, plate cold rolling: the plate processed in step S2 is rolled into a cold-rolled plate by a four-roll cold rolling mill;
[0040] S4, inspection and screening: the cold-rolled sheet in step S3 is inspected manually, and the cold-rolled sheet with obvious scratches and streak defects on the surface of the sheet is removed;
[0041] S5...
