摘要
为了消除无缝钢管轧制后的纵向弯曲及圆度误差,一般要采用矫直工艺。矫直工艺决定了无缝钢管的几何形状,同时也影响其力学性能。文章建立了符合无缝钢管规范要求的矫直力学模型,对无缝钢管矫直时的变形规律进行了分析,同时建立了有限元分析模型。
The straightening process is generally used to eliminate the longitudinal bending and the roundness error of the wiled seamless steel pipe. It determines their geometrical sizes and influences their mechanical properties. The mechanical model of straightening is established that meets the requirement to make the seamless steel pipe. The deformation laws during the straightening are analyzed, the finite-element analysis model for the straightening of seamless steel pipe is established.
