本文从剖析现代轧管工艺入手,大胆地提出了将纵轧与自由辊行星斜轧两种工艺结合在一起的纵—旋轧管设想。介绍了纵—旋轧试验情况。阐述了对纵—旋轧管工艺的初步认识。认为一旦这种工艺设备成熟后,将成为连续轧管机组的有力竞争对手。 Starting with the analysis of the modern tube rolling process, this paper boldly put forward the idea of ​​longitudinal-rotary tube combining the two processes of vertical rolling and free-rolling planetary beveling. The condition of longitudinal-rolling test is introduced. The initial understanding of the longitudinal - pipe rolling process is expounded. It is believed that once the process equipment is mature, it will become a powerful competitor of the continuous tube rolling mill.
