摘　　要：对钢管张力减径机组孔型设计进行了研究,提出了一种新的孔型设计方法。并采用ANSYS/LS-DYNA软件对准48 mm×6 mm的20钢管进行了减径过程有限元模拟,对轧制过程中单辊轧制力、钢管壁厚以及钢管速度的变化进行了分析。最后,进行了钢管三辊减径实验,获得了符合要求的钢管,证实了该孔型设计方法是合理的。The roll grooving design of tube tension reducing mill was researched. A new method for grooving design was proposed. The reducing process of the φ48 mm×6 mm steel tube was simulated by using ANSYS / LS-DYNA software. Single-roll rolling force, change of wall thickness and tube velocity in rolling process were analyzed. Finally, the experiment of three-roll steel tube reducing process was carried out and the steel pipes of meeting the requirement were obtained, which affirmed that the grooving design method was reasonable.
