In the manufacture of aluminum and aluminum alloy strips and materials, such as the thickness of the plate and strip manufacturing, it can be divided into thick plate, medium plate, thin plate and aluminum foil. The thickness of ≥ 8.0mm is called thick plate; the thickness of 5.0-8.0mm is called medium plate; the thickness of 0.2-5.0mm is called thin plate, the thin plate is called strip; the thickness is less than 0.2mm. For aluminum foil. At present, most enterprises in the world use a pair of flat rolls to longitudinally roll aluminum alloy sheets and strips. Aluminum and aluminum alloy sheets and strips can be manufactured into the following types:
1) According to the rolling temperature, it can be divided into hot rolling, warm rolling and cold rolling.
2) According to the manufacturing method, it can be divided into block rolling and belt rolling.
3) According to the rolling arrangement, it can be divided into single-stand rolling, multi-stand semi-continuous rolling, continuous rolling, continuous casting and continuous rolling and continuous casting and rolling.
In the manufacturing practice, the appropriate manufacturing method can be selected according to the alloy composition, variety, specification, use, quantity and quality requirements, market demand, equipment configuration and national conditions.
