Abstract
In this paper, premature failures of several work rolls on a cold strip mill were investigated. In order to study the work roll surface feature and failure mechanism, the chemical compositions, microstructures and the hardness of roll materials were examined. The stresses in the spalled area of the work roll have been calculated, and the stress states identified. The causes for the roll wear and damage have been identified in the study. The surface images of the work rolls have been studied, and the characteristics of wear have also been characterised for the damaged rolls. It has been found that the operating factors and metallurgical defects affected the roll service life in cold strip rolling.

概述
在本文中，对几个冷连轧机工作轴过早失效进行了调查。为了研究工作轴表面特性和破坏机理，化学成分，微观结构和轧轴材料的硬度进行了研究。已计算在工作轴剥落面积的压力，确定应力状态。在研究中，轧轴磨损和损坏的原因已经查明。对工作轴表面图像进行了研究，发现了已损坏的轧轴磨损特性的特点。人们已经发现，经营的因素和冶金缺陷将影响在冷轧带钢轧轴的使用寿命。
