A series of flexible U sections, changed in its sections, was separately simulated and analyzed by edger roll forming and flat roll forming.

基于中厚板无切边轧制法中立轧轧边变形的物理模拟，分析了平辊立轧与倒棱轧制对中厚板断面形状的影响。

T he relation of the four parameters with initial slab thickness, initial slab width, width reduction and edger roll diameter was obtained and a new mathematical model was accomplished as well.

得出表征立轧时轧件断面特征的四个参量与侧压量、立辊直径、板坯来料厚度及宽度间的关系，并建立了新的数学模型。
