What is the process function of hot rolled seamless steel tube?
Pipe rolling – the processing of the wall thickness of the capillary is usually called pipe rolling. Pipe rolling is the most important process in the process of steel pipe forming. The main task of this link is to reduce the thick wall capillary to the extent suitable for the finished steel pipe according to the requirements of the finished steel pipe, that is, it must take into account the change of wall thickness in the subsequent sizing and reducing processes. This link also needs to improve the internal and external surface quality of capillary and the uniformity of wall thickness. The pipe after the wall reduction and extension process of pipe rolling is generally called waste pipe. The basic feature of pipe rolling wall reduction method is to press a rigid mandrel in the capillary and compress the wall thickness of the capillary by external tools (roll or die hole). According to different deformation principles and equipment characteristics, it has many production methods. ...
