In order to improve the efficiency of aluminum production, to ensure a reasonable finish rolling temperature, in the device allows the use of high-speed rolling so far. In the aluminum actual production process, should determine the different speeds depending on the rolling rolling stages. 1. Start rolling Shandong large-diameter tubes stage system manufacturers, ingot thick and short, absolute reduction greater difficulty biting large diameter tubes Shandong, in order to facilitate the bite, usually a lower rolling speed. 2. intermediate rolling stage, in order to control the finish rolling temperature and increase productivity of large diameter tubes, as long as conditions allow, as far as possible the use of high-speed rolling. 3. Finally rolling stage. because the strip becomes thin and long, rolling temperature drop big loss strip and roll the contact time is longer, in order to obtain an excellent surface quality and good aluminum plate, should be based on the actual situation, the appropriate choice of rolling speed. This helps reduce the impact on the mill, to protect the safety equipment. quality standards aluminum coil, the surface can not have a clear indentation, holidays, through the coating damage, and ripples, scratches, bubbling are not allowed. These are easy to see, the most important thing is you have to look carefully aluminum coil color, if not pay attention to Ji'nan large diameter tubes, it is not easy to see, but at the time of application will affect the final decorative effect. The current aluminum curtain wall will do with electrostatic spraying surface treatment, powder coating materials mainly for polyurethane, swelling resin, epoxy resin and other raw materials with high color retention pigment obtained dozens of different colors powder coating, decorative the effect is also very good.
