本文对冷轧工作辊辊面剥落的三个阶段作了宏观和微观的形态分析。并从理论和机构上论证了粘裂、热冲击、非金属夹杂物和粗晶结构对形成微裂纹的影响。通过油楔作用和剪切应力定量地解释了裂纹发展的可能性及其方向。从钢的化学成分和纯净度等六个方面提出了延长轧辊使用寿命的意见。 In this paper, macroscopic and microscopic morphological analysis of the three stages of the work roll surface peeling off. The effects of sticking, thermal shock, non-metallic inclusions and coarse grain structure on the formation of microcracks were demonstrated theoretically and mechanistically. Through the oil wedging effect and shear stress, the possibility and direction of crack development are explained quantitatively. From the steel chemical composition and purity of six aspects put forward to extend the service life of roller opinion.
