Steel Tube Rolling

- Jul 03, 2017-

Continuous rolling process is used for continuous rolling and sizing reduction of steel pipe. Steel tube rolling is a process in which a steel tube and a mandrel move together in a plurality of racks, and the deformation and movement of the steel tube are simultaneously subjected to the interaction of the roller and the mandrel. The mandrel can be free floating, that is, the metal can be moved forward by the metal; it can also be a limited motion; that is, a movement speed is given to the mandrel to limit its free motion. In the process of movement, mandrel, roller and pipe connection into a whole, change any of them a link will change the state of the system, rolling theory is the study of the relationship between the theory of.
