Mechanics of transverse friction and roughness in cold strip rolling

横向摩擦和粗糙度对轧制带钢的形状和表面质量有显著影响。然而，冷轧过程中横向摩擦的机理尚未得到明确的认识。在本项目中，将建立一个二维混合膜润滑模型，该模型耦合带钢变形和辊堆变形，以量化横向摩擦和粗糙度对带钢形状和表面质量的影响。它将扩展摩擦和粗糙度分析的范围，远远超出其他现有模型。

The transverse friction and roughness have a significant effect on the shape and surface quality of the rolled strip. However, mechanics of transverse friction in cold rolling have not been identified clearly. In this project, a two-dimensional mixed film lubrication model, which couples with the strip deformation and the roll stacks deformation, will be developed to quantify the effects of transverse friction and roughness on strip shape and surface quality. It will extend the scope of friction and roughness analysis well beyond other existing models.
