Aluminum alloy straightening process

Straightening process
During the hot rolling process of aluminum plates and aluminum coils, the longitudinal uneven extension and internal stress caused by improper temperature, pressure, roll shape changes, and process cooling control will cause poor plate shape.
The cold rolling process with perfect control means can only partially improve the plate shape. At the same time, poor plate shape may also occur during the cold rolling production process. The final elimination of plate shape defects must be achieved through the finishing straightening process.
The precise straightening of aluminum plates and aluminum coils is divided into 4 straightening methods according to the equipment configuration and application scope:
roller straightening, clamp-type stretch straightening, continuous stretch straightening, and continuous stretch bending straightening.
Among them, continuous stretch straightening is pure tension straightening, continuous stretch bending straightening, and these two are collectively referred to as tension straightening.
Roller straightening and clamp-type stretch straightening are mainly used for straightening of aluminum plates.
Continuous stretch bending straightening and continuous stretch straightening are used for straightening of aluminum coils.
