Generally speaking, the shape of aluminum coil plate can be repaired and adjusted only by processing, but the shape of the whole aluminum coil plate cannot be fundamentally changed. Therefore, the shape of the original aluminum coil plate directly affects the shape and dimensional accuracy of the finished aluminum coil plate, as well as the quality of the aluminum coil plate and the horizontal surface of the product. Do you know the specific influencing factors? How much do you know? Is it not clear? It doesn't matter. Next, the aluminum coil manufacturer will introduce it to you.
(1) Effect of alloy state on flatness
Generally speaking, the greater the hardness of aluminum alloy, the more difficult it is to control and adjust the shape of aluminum strip in the finishing process. When controlling and adjusting the aluminum plate and strip, the finishing personnel should cooperate with the previous process control personnel and cross cutting finishing operators.
After making scientific and reasonable judgment, it is necessary to choose appropriate means to straighten the shape of aluminum strip and steel plate. If it is impossible to produce aluminum strip sheet, the adjustment and control of aluminum strip sheet shape should start from adjusting tension, idler position, etc., and strengthen the adjustment of relevant parts.

(2) Influence of installation grade and quality of unit on shape of aluminum plate and strip
Aluminum coil manufacturers said that the installation level of finishing equipment will directly affect the shape of aluminum strip, and the installation level is determined by the local investment policy and the investment cost of aluminum strip finishing process. The installation quality of the train shall be based on the perpendicularity between the middle line of the train and the equipment.
(3) Influence of straightener roll position on aluminum strip shape
At present, the leveling of the roller position is not enough when straightening the aluminum strip in the finishing process, mainly due to the adjustment of the roll position in the production process. In the process of roll replacement and adjustment, the levelness of the upper roll and the lower roll may not be enough at the same time, or one of the upper roll and the lower roll may not be enough. Insufficient levelness of upper and lower rolls may cause double edge wave or single edge wave on the straightened strip.
Strip deviation is also one of the reasons that affect the bad shape of aluminum strip. Therefore, operators should often check the levelness of the straightener to ensure that the shape of aluminum plate and strip is effectively controlled in the actual finishing process.
Aluminum coil manufacturers have introduced the influencing factors of aluminum coil shape above. I believe you will have a new understanding after reading it. If you want to know more, you can pay more attention to our website: http://www.jndclyyxgs.com Hope to help you.
