The output of aluminum alloy aluminum plate aluminum strip aluminum coil and aluminum foil accounts for about 60% of the total aluminum processing. Since these aluminum plates, aluminum coils and aluminum foils are widely used, the rolling technology of aluminum alloys has also developed rapidly.
1. Hot rolling machines are developing in the direction of large-scale, automated control and precision. The method of only two rolling mills has been eliminated. Appropriately develop the production method of hot rough rolling and hot finishing rolling, and vigorously develop the hot continuous rolling production method to greatly improve the production efficiency and the quality of aluminum plates.
2. Continuous casting and continuous casting and rolling are developing in the direction of high speed, high precision and ultra-wide thin wall.
3. Cold rolling is developing in the direction of wide width width greater than 2000 mm, high speed, maximum speed of 45 meters per second, and highly automated control. And the cold continuous rolling process has begun to develop, which can greatly improve production efficiency.
4. The rolling of aluminum foil is developing towards wider, thinner, more precise and more automated directions. Ultra-thin aluminum foil of 0.004 mm can be produced by double rolling with different thicknesses. At the same time, other methods of producing aluminum foil such as spray forming have been developed.
