Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy plate processing, and in particular to a rolling device for an aluminum alloy strip and a processing method thereof. Background Art

[0002] Aluminum alloy sheet and strip rolling is a processing technology that processes aluminum alloy ingots or billets through pressure processing such as rolling, so that they are gradually thinned in the thickness direction, and the length and width directions change accordingly, and finally form plate-shaped or strip-shaped aluminum alloy materials. This is a very important link in aluminum alloy processing. Through rolling, aluminum alloy sheets and strips of various specifications can be produced to meet the needs of different industrial fields.

[0003] At present, the rolling process of aluminum alloy plates and strips mainly rolls the aluminum alloy plates through rolling rollers. In order to achieve the rolling effect on the aluminum alloy plates, the gap between the rolling rollers and the support rollers needs to be gradually reduced. Although the aluminum alloy plates can be rolled into aluminum alloy plates and strips, this will undoubtedly lead to an excessively large volume of the rolling device, resulting in an excessively large floor space.
