冷轧过程组合式支承辊过盈配合面微动滑移分 布特性研究 Introduction: The combination support roller is an important component in the cold rolling process of steel. During the cold rolling process, the support roller bears the weight of the steel strip and provides support to the rolling mill. The accuracy of the roller's dimensional and rotational stability is critical for the quality of the rolled steel products. Therefore, it is essential to study the fitting characteristics of the combination support roller to ensure the quality of the cold rolling process. Roller Fitment: The combination support roller of the cold rolling mill has atight fit with the support shaft, and the matching surface has aslight gap. The minimum clearance between the shaft and the matching surface is called the overhang clearance. In the process of cold rolling, the overhang clearance plays a significant role in maintaining the stability of the roller and reducing wear. Micro-Slip Distribution: The overhang clearance also affects the micro-slip distribution of the roller fitting. In the cold rolling process, the steel strip passes through the rollers, which rotate to create the desired shape and thickness. The rollers' rotation speed is different from the steel strip's speed, leading to amicro-slip between the steel strip and the rollers. The overhang clearance affects the micro-slip distribution, which, in turn, affects the quality of the rolled steel products. Research Methods: To study the overhang clearance's effect on micro-slip
