| 摘要: |
| 针对带钢冷轧过程中磨损量仅有微米或亚微米数量级的工作辊表面微观形貌的轧制磨损，建立元胞自动机磨损模型，模拟工作辊表面微观形貌的轧制磨损行为及其动态变化过程。采取不同频率正弦曲线叠加组合对工作辊表面形貌的圆周向轮廓进行数学描述和建模，结合生产实际和已有研究，确定接触咬合磨损与磨粒磨损的元胞状态转换规则，建立元胞自动机原理工作辊表面磨损演化模型，并模拟得到在不同工况条件下工作辊表面微观形貌的磨损规律，仿真研究所得粗糙度磨损演变规律与在工业生产中实测统计获得的磨损演变规律基本吻合。 |

| Abstract: |
| A cellular automata model was established for the micron or submicron level wear of a working roll in cold rolling of strip steel. The wear behavior and dynamic surface morphology change of the working roll were simulated based on the combination of two main mechanisms: the adhesive wear and the abrasive wear. The microcosmic circumferential profile of working roll was described by the superposition of sine curves with different frequencies. Based on industrial experiences and former researches, the cellular state transfer rules of the adhesive wear and the abrasive wear were established. Finally, the wear evolving model of the working roll was built based on the cellular automata mechanism. The surface wear principles of the working roll surface morphology under different operating conditions were obtained. The simulated results of the wear volume and surface roughness changes of the working roll agree with the results from field measurements. |
