Problems solved by technology

[0008] However, when this method adopts the finished product annealing process, the requirements for the uniformity of the annealing temperature are high, the temperature control of the annealing furnace is high, and the performance is unstable, especially the yield strength; at the same time, if the cold rolling oil is not cleaned completely, the finished product annealing temperature Relatively low, it is not easy to remove cold rolling oil, and it is easy to produce surface defects such as oil spots, and the surface quality cannot meet the surface requirements of some products, especially advanced anodized appearance materials
