Rolling classification

According to the motion of the rolling piece, the rolling methods are divided into: longitudinal rolling, cross rolling, and cross rolling.
The longitudinal rolling process is a process in which metal passes between two rolls that rotate in opposite directions and produces plastic deformation between them.
Cross rolling: The direction of movement of the rolled piece after deformation is consistent with the direction of the roll axis.
Skew rolling: The rolling piece moves in a spiral, and the rolling piece and the roll axis have no special angle.
According to the metal state, there are: hot rolled cold rolled.
