Aluminum alloy strip material rolling method

Abstract

The embodiment of the invention discloses an aluminum alloy strip material rolling method. The method comprises the following steps: measuring the maximum critical friction force, namely a first friction force, between a roller and an aluminum alloy strip material when the aluminum alloy strip material revolves transversely; and controlling the friction force between the roller and the aluminum alloy strip material to be not less than the first friction force when the roller rolls the aluminum alloy strip material. In the technical scheme provided by the embodiment of the invention, in the aluminum alloy strip material rolling process, the friction force between the roller and the aluminum alloy strip material is improved to avoid the transverse revolving of the aluminum alloy strip material so that the stress among layers can be distributed uniformly and stress concentration is prevented, thereby avoiding or reducing rolling damage defect. Compared with the prior art, in the scheme, the rolling speed does not need to be reduced, thickness of an oil film on the surface of the aluminum alloy strip material does not need to be reduced, therefore the defect of rolling damage in the aluminum alloy strip material rolling process is overcome on the premise of not influencing the production efficiency and not increasing the production cost, and the product quality is improved.

Description

Technical field: [0001] The invention relates to the technical field of mechanical processing and manufacturing, in particular to an aluminum alloy strip rolling method. Background technique: [0002] In industrial production, when using high-speed rolling mills to roll aluminum alloy strips, especially when rolling some high-strength aluminum alloy strips, due to problems such as deformation and heat generation of aluminum alloy materials, poor sheet metal or uneven lubrication, it is easy to The transverse movement of the aluminum alloy strip is caused, resulting in interlacing between layers during the coiling process, resulting in coiling sticking defects. As a common defect in aluminum alloy strip rolling, the coiling sticking defect seriously affects the quality of the product. Therefore, the occurrence of this defect should be strictly controlled in the actual production process. [0003] Such as figure 1 Shown is a schematic diagram of the aluminum alloy strip duri...

AI Technical Summary

Problems solved by technology

[0004] However, reducing the rolling rate will inevitably affect production efficiency, and increasing the thickness of the oil film on the surface of the aluminum alloy strip will increase the production cost. Therefore, the existing solutions to the problem of coiling sticking are not conducive to large-scale promotion and application
