摘要: 針對動態板形輥(DSR)寬帶鋼冷軋機的板形控制性能存在垂直不對稱的問題,通過建立全輥系模型,運用ANSYS有限元軟件,對其特殊的板形控制性能進行了數值計算.定量研究了國內某廠引進的DSR軋機的板形控制性能及其垂直不對稱性,分析了這種不對稱性的產生原因,并制定了減輕其危害的具體對策.Abstract: The dissymmetry of flatness control in the vertical direction is the characteristic of a DSR (dynamic shape roll) mill. By constructing the finite element model for whole rolls, the flatness control behavior was numerically calculated by using ANSYS software. After evaluating the flatness control behavior and the vertical dissymmetrical characteristic of a DSR mill in China, the reason for dissymmetry was pointed out, and the measures of moderating the dissymmetrical harms to shape was proposed.
