What are the defects in the shape of hot-rolled aluminum alloy plates

The aluminum plate is not straight and presents a concave and convex state. The degree of concave and convexity of the aluminum plate is generally determined by the wave height, wave spacing and wave beam in the rolling direction, which will affect the customer's use of the aluminum plate.

The edge wave refers to the edge of the aluminum plate, which is uneven and the edge of the aluminum plate repeatedly waves, which will affect the customer's use of this aluminum plate.

The middle wave is the unevenness of the center of the aluminum plate. The repeated waves in the center of the aluminum plate will prevent customers from using this aluminum plate.

The 1/4 wave is along the horizontal direction to the aluminum plate, and the edge distance is 1/4 of the plate width It is uneven, or there is a slight degree of unevenness close to the edge, which will affect customers' use of the aluminum plate.

Short-cycle scooping refers to the short-cycle unevenness on the aluminum plate when it is in the magazine, and any position and direction of the aluminum plate. The short-cycle peak and back of the wave between 500 mm. It cannot be used if it exceeds the standard.
