2024 aluminum plate generally needs to go through the process of casting and rolling before forming. Then fission may occur during casting and rolling. At this time, how do we control it?Next 2024 aluminum plate manufacturers to introduce to you, 2024 aluminum plate casting and rolling crack edge control method.

2024 Aluminum plate casting and rolling crack edge will reduce the casting and rolling yield, at the same time, the crack edge will increase the amount of oil in the edge, increase the rolling oil consumption, increase the difficulty of oil removal, cause oil spot, affect the surface quality of the plate and strip.

The casting and rolling zone is composed of liquid phase zone, two phase zone and rolling deformation zone.Roll casting process, when the strip roll contact surface and the inner temperature difference is bigger, the rolling deformation, surface deformation, low working temperature are less strip center environment high temperature deformation, 2024 aluminum plate surface and roll surface without the relative sliding, 2024 by rolling thin aluminum plate making center, and after the metal part of the students produce a large sliding, both between each other can generate shear stress, produce different deformation, and information transfer to the fluid cavity shell, the shell of the internal management development through the same deformation and shear forces.When the shear force produced by the deformation exceeds the shear strength of the solidified shell metal, the edge of the strip will crack at first. The edge of the strip is affected not only by the shear stress, but also by the post-friction force exerted by the ear on the side of the strip and the transverse rolling force.

According to different alloy composition, the casting and rolling edge of 2024 aluminum plate can be effectively controlled by adopting appropriate control of casting and rolling process parameters.The casting and rolling crack edge of 2024 aluminum plate can be controlled at about 3mm.The processing sequence of the casting edge crack is reduced, and the fuel side of the strip is reduced, so the fuel consumption is reduced and the plate quality is improved.

The above is the control method of casting and rolling crack edge of 2024 aluminum plate. If you need 2024 aluminum plate, please contact us.
