Copper strip control surface quality measures

Copper strip high purity, fine tissue, oxygen content is very low. It has good electrical conductivity, thermal conductivity, corrosion resistance and machining properties, and can be welded and brazed. Measures to control the surface quality of red copper strip: first of all, we should strengthen the control of the production process. Use brush and water to clean up the impurities on the surface of the red copper strip, and wrap with lining paper before rolling to prevent the surface from being scratched. In addition, the all-oil rolling method should be adopted, the oil removal device of the mill should be modified, and the rolling speed should be slowed down, and all feasible measures should be taken to remove residual contaminants from the surface. At the same time, production management personnel to strengthen production management, increase monitoring efforts.

Secondly, the protection of inert gases during heat treatment should be strengthened. Since copper has very active chemical properties, it can react quickly with more active gaseous substances in the air when heat treated at high temperature. Then it is necessary to protect the inert gas more effectively to prevent the copper strip from being oxidized. When necessary, the appropriate increase of inert gas is also one of the feasible methods.

Again, of course, it is necessary to strengthen the surface cleaning, maintain a high degree of finish. In rough rolling and annealing process, copper strip surface will inevitably produce oxide, so the necessary cleaning methods such as pickling, degreasing, passivation to ensure that the implementation of good.

Strengthen the control of finished product packaging. The copper strip must be dried after pickling. The humid environment will speed up the corrosion of copper and affect the precision of the finished product. Therefore, in order to ensure the drying of the product, it is necessary to take a double approach, while drying the finished product as much as possible, but also working on the packaging. When packing, the packing box can be padded with moisture-proof paper, and then wrapped with plastic bags, so as to effectively prevent the influence of external moisture during transportation.
