High-stability metal ultra-thin strip machining technology

Abstract

The invention discloses a high-stability metal ultra-thin strip machining technology. The technology comprises the following steps that Step 1, a copper alloy, an aluminum alloy, steel and titanium are used as materials and are placed in a resistance furnace, homogenization treatment is performed at the temperature of 1800 DEG C, and the materials are poured into a mold of 5-10 mm to be cooled, so that a rolled piece is obtained. The copper alloy, aluminum alloy, steel and titanium materials are subjected to uniform treatment in a molten state and then cooled to obtain the rolled piece, subsequent annealing can be reduced or eliminated, shearing force can be generated on the surface of the rolled piece in a compression mode by the aid of two compression rollers with different rotating speeds, by means of the low-cost mode of pressing and shearing combined asymmetrical rolling, the coiled metal ultra-thin strip with the thickness smaller than 6 micrometers is prepared, the cost is saved, and meanwhile, the flowing speed of the metal ultra-thin strip can be increased.

Description

technical field [0001] The invention relates to the technical field of ultra-thin metal strips, in particular to a high-stability ultra-thin metal strip processing technology. Background technique [0002] In recent years, the rapid development of high-tech fields such as micro-manufacturing, electronics, and computers has raised some micro-materials and micro-forming issues. The micro-materials and micro-devices required by these cutting-edge micro-manufacturing fields are smaller in size and require higher precision. The production level of ultra-thin strips has become the key to realizing micro-manufacturing and promoting product miniaturization. [0003] At present, when producing ultra-thin metal strips, the process of heating and annealing is basically required during the rolling process. Therefore, the production of ultra-thin strips is not only costly, but also time-consuming and laborious, and the current rolling machine There will be impurities such as oxides on t...
