摘要
采用三维流函数速度场按上界法解析了厚件平辊轧制问题。解析中考虑了宽展和侧鼓形的变形特点,以及坯料的宽厚比、辊径、摩擦因子、压下率等主要因素对宽展率和相对单位力的影响。解析结果与实验结果基本相符合。为制订合理的轧制工艺,以及对宽展的估计提供了理论依据和计算方法。
An upper bound method of triaxial fluxional function velocity field is used to analyse thick slab rolling in this paper. Some main factors affected to broadening ratio and rolling pressure are considered in this analysis. The factors include the deformation habit of broabening and side bulge, slab broadness-thickness ratio roller radius, frictional factror and compression rate. The results is basically consistant with experiment. It provides a theory basis and calculation method for making reasonable rolling-technology and broadening estimation
