摘要： 针对某钢厂棒材矫直过程中二辊矫直机导板间距没有明确规定并且导板磨损严重的情况,用大型非线性有限元软件建立了棒材二辊矫直过程的三维弹塑性有限元模型.基于此模型研究了不同导板间距下矫直力、导板支撑力、塑性变形程度、矫后残余应力及最大挠度的变化规律,综合分析提出了合理的导板间距取值范围.新的导板间距比之前实际应用的值有所增大,应用后导板更换频率降低.

关键词: 金属材料, 轧制, 二辊矫直, 导板间距

Abstract: As reasonable interval between guides during two-roll straightening process was not easy to determine, a 3D elastic-plastic finite element model of the straightening process of bar material was proposed. Based on this model, variations of straightening force, supporting force of guides, degree of plastic deformation, residual stress and the maximum deflection of the bar after straightening were analyzed in different intervals. Reasonable range of interval between guides was determined by comprehensive consideration. The obtained range of interval by this study is larger than previously used range, and the frequency of change of guides is decreased.

Key words: metallic materials, rolling, two-roll straightening, interval between guides
