轧制是将金属坯料通过一对旋转轧辊的间隙（各种形状），因受轧辊的压缩成型

Rolling <br>is a press working method in which a metal billet is passed through a gap (various shapes) of a pair of rotating rolls, and the cross-section of the material is reduced and the length is increased due to the compression forming and rolling of the rolls. <br>Rolling classification: <br>According to the movement of the rolling piece, it is divided into: vertical rolling, horizontal rolling, cross rolling. <br>Longitudinal rolling: It is a process in which metal passes between two rolls that rotate in opposite directions, and plastic deformation occurs between them. <br>Cross-rolling: The moving direction of the rolled piece after deformation is consistent with the direction of the roll axis. <br>Skew rolling: The rolling piece is in helical motion, and the rolling piece and the roll axis are not at a special angle.

ollIt is a pressure processing method in which the metal blank passes through the gap (various shapes) of a pair of rotating rolls, and the cross section of the material is reduced and the length is increased due to the compression molding rolling of the rolls.Rolling classification:According to the movement of rolled pieces, there are longitudinal rolling, transverse rolling and skew rolling.Longitudinal rolling: It is the process in which metal passes between two rolls with opposite rotation directions and plastic deformation occurs between them.Transverse rolling: the movement direction of the rolled piece after deformation is consistent with the axis direction of the roll.Inclined rolling: the rolled piece moves spirally, and the rolled piece is at a non-special angle with the roll axis.
