摘要
Abstract
Heating-while-expending steel pipe is required in the production process of large-diameter steel pipe, but there are some shortcoming , such as high heating power , poor expending efficiency , and coarse grain.Hot-expending machine for Φ1 300 mm large-diameter steel pipe was developed by shaanxi doron tech-nology development Co., Ltd., it is high production efficiency , energy conservation and short process this expen-der.Centering restraint device with four-jaw independent chuck was used in this expender , which decreased de-formation of end pipe and restrained circumferential deformation .The device does guarantee cylindricality .关键词
