摘要: 根据钢管在张力减径时的变形特点,利用ANSYS软件对21机架张力减径机进行三维建模有限元分析,模拟荒管在减径过程中的变形过程,比较圆孔型参数模拟和椭圆孔型参数模拟时荒管产生“内六方”的趋势和壁厚变化情况。分析认为,采用椭圆孔型参数模拟时,荒管产生“内六方”的趋势较小,且壁厚波动也较小。

Abstract: According to the deformation characteristics of the steel pipe during the stretch-reducing process,the rolling process of the 21-stand stretch reducing mill is finite element analyzed (FEA) with the 3D model as set up via the ANSYS software.The analysis involves simulating the deformation course of the pipe being reduced,and a comparison of the pipe hexagonal ID occurrence trend and wall thickness variation resulting from the round pass parameter simulation to those resulting from the oval pass parameter simulation,which leads to the conclusion that in case of the oval pass parameter simulation,the occurrence trend of the hexagonal ID formation is smaller,and the wall thickness variation is also rather less.
