摘要
利用显式动力学有限元方法模拟了不同轧制参数条件下H型钢的变形过程,得出了一些主要参数对H型钢后滑的影响规律,并对这些规律产生的原因进行了分析·研究结果表明:压下率对H型钢后滑的影响非常明显,随压下率的增加,后滑急剧地增加·此外,轧件的腿宽、腿腰延伸比、内宽以及轧件的初始厚度对H型钢的后滑也有较明显的影响·
The deformation process of H-beam was modeled by the explicit dynamic finite element method with different rolling parameters to make sure how and why the backward slip formed during H-beam rolling. The results showed that in the rolling process of H-beam the influence of area reduction on backward slip is so apparent that the backward slip increases sharply with increasing reduction. In addition, the flange width, elongation ratio of flange to web, inner width of H-beam and initial thickness of workpiece also affect greatly the formation of backward slip during H-beam rolling.
