摘　　要：结合生产实际,采用ABAQUS显式动力仿真平台,对宝钢140mm全浮动芯棒钢管连轧过程中金属的变形及流动规律进行了仿真分析.分析结果表明:金属的横向流动主要表现为从孔顶区域流向侧壁区域;金属的纵向延伸主要发生在孔顶区域,且钢管外壁金属相对内壁金属向前滑移.孔型侧壁区域金属的横向堆积及纵向延展不充分是导致荒管壁厚不均的主要原因.Based on production practice, the ABAQUS explicit dynamic simulation platform was used to investigate the metal deformation and flow rule during tube continuous rolling by the Baosteel Ф140 mm full float mandrel mill. The results show that the transverse metal flow is mainly from the groove top to sidewall, and the longitudinal metal extension occurs chiefly in the groove top area, while the outer wall metal of steel tubes slides forward relative to the inner wall metal. Transverse metal accumulation and longitudinal inadequate extension in the groove sidewall area are the main reasons to cause non-uniform wall thickness.
