People often ask me, aluminum foil mill daily maintenance should be how, today zhuozhou Feiya Machinery Co., Ltd. will tell you.
Due to the frequent use of VC roller in production, the control of VC oil pressure directly affects the shape quality of aluminum foil. Too small oil pressure will cause edge waves in strips, while too large oil pressure will cause intermediate waves in strips. Only moderate oil pressure can obtain straight strips [6]. Usually in the production process, there are often more complex asymmetric shape defects, so the shape automatic control system will make VC roll system and other control means of one or several at the same time to participate in the adjustment, such as hydraulic bending roll, roll tilt, rolling force, roll cooling system, etc.. When VC roll and hydraulic bending roll are used together, a variety of different roll gap shapes can be obtained. The influence range of dynamic roll gap setting system is obtained by the combination of these two systems. When the VC roller participates in the action, increasing the VC pressure can make the whole bending roll action range move to the right and lower part, so that the whole control window can adapt to the range becomes larger. The participation of the VC roller system can make a considerable improvement in the flatness of the strip to meet the requirements of users for small flatness tolerances.
The four high cold rolling mill and aluminum foil mill with variable crown back-up roll are developed in view of the limited ability of the bending roll of the traditional cold rolling mill and aluminum foil mill to adjust the parabolic shape deviation. At present, the use of the variable crown back-up roll is mainly divided into two categories: one is the full length of the variable crown back-up roll, the second is to change the end diameter, the middle of the flat part of the width of the back-up roll, by adjusting the crown to affect the overall crown, such as TP roll and SCR roll. After commissioning and running, 1800mm aluminum cold rolling mill can produce various specifications of strip and can roll 0.06mm aluminum with thickness deviation of 10μm and normal speed of about 10m/s.
