ZTF is a forming technique developed by ZTZG in 2005. It allows the shared-usage of rollers during break-down section when forming pipe, saving significant mould and labor cost while greatly improving production efficiency. It earns the reward of technology Innovation Award' by 'China Cold Forming Steel Association9 in 2010. After absorbing advanced pipe making technology from both abroad and domestic, our innovative designed production line and each single unit of the production line are not only economical but also practical.
Throughout the years, ZTZG has developed 4 generation for ZTF techniqueFirst Generation
DSS technique directly reel the strip steel into desired sized tube with several distinct advantages.It adapts the multipoint bending method,which avoids the axial force and side abrasion,reduces the forming step,and ensures high quality.Compare to Round-to-Square(RS)forming technique,DSS creates better outer edge and smaller inner arc for the cross section of the tube,and the brimis flatter with more regular outlook.With our new DSS-3 technique,only one set of rollers is needed for the entire mill with no need for any roller or spacer replacement,which achieves full-automatic adjustment for roller positions,significantly increasing production efficiency and reducing labor cost and risk of hazard.
