Analysis of flow and stresses in a tube stretch

2003-3-1  1. Introduction. Tube stretch-reducing rolling is a basic process in industrial tube production. In this process, the tube diameter and wall thickness are reduced by passing the tube, without internal support, through a set of successive three-roll hot rolling stands in which calibrated inter-stand axial tension is introduced by controlling the stand's relative speeds.
