The kinematics of steel pipes rolling phenomenon

The continuation of rolling process for steel pipe rolling and reducing process. steel pipes rolling is a steel pipes with mandrel movement process in the multiple frame, and steel pipe deformation and movement of the rollers and mandrel work together. Can is a free floating mandrel, also is all by metal drive forward movement; Can also be a limit of lift, that is, to a speed of rods, limit the freedom of movement. In the process of movement, the mandrel, roll and steel pipe connection into a whole, the change of any one of these links will cause the change of the state of the system as a whole, and rolling theory is the theory of study of the relationship between them.
