Surface quality control is the whole process of copper busbar production to product packaging control, is a fine management, careful operation of the system engineering, each process is the key to control product surface quality.
The quality of billet surface is greatly affected by whether the continuous extruder cooling system is normal or not. Firstly, the cooling water channel of continuous extruder is reformed, and the cooling water temperature is in the ideal state. Second, according to the actual production, a reasonable proportion of lubricating additive liquid + water is adopted to cool the surface of the blank. The surface quality of the billet has been obviously improved by the transformation of the cooling waterway of the continuous extruder and the use of lubricating additives. The surface of the billet is smooth and bright without oxidation.
The drawing die is lubricated with a water-based lubricant, which is a water-soluble drawing oil. The water-soluble drawing oil has a very high lubricating effect. It continuously provides a lubricating and anti-friction film during plastic deformation, which can effectively improve the surface quality of the copper busbar and effectively reduce the occurrence of scratches and scratches. It has good extreme pressure and anti-wear performance, which is beneficial to protect the mold and prolong the life of the mold. The cooling performance is good, and the drawing oil is completely dissolved in water, which greatly saves the comprehensive use cost. Easy-to-clean product, good stabilization effect, clean workshop environment. It has extremely high wettability and can effectively improve the roughness and precision of copper busbars. Excellent rust resistance, will not corrode sensitive metals. Environmentally friendly products, the additives do not contain sulfur and phosphorus, meet the requirements of environmental protection, and have no effect on the skin. Since the lubricant contains a large amount of water, it is easy to deteriorate. During the use process, attention should be paid to maintenance and monitoring, and it should be replaced regularly according to regulations. Through the use of water-based lubricant, the surface color of the copper busbar is smooth and uniform, and the surface quality has been significantly improved.
