Steel Pipe Rolling

Rolled steel rolling process for the continuation of the process and reducing fixed. Steel rolling is a process of moving together by steel and mandrel in multiple racks, steel deformation and movement as well as by common action rolls and mandrel. Mandrel can be free floating, that is, thanks to the forward movement of the metal drive; it can be limited to acting, that is a given mandrel speed of movement, limiting their freedom of movement. During exercise, mandrels, rolls and steel contact as a whole, where any one part of the change will lead to changes in the status of the entire system, rolling theory is the study of the theory of the relationship between them.
