摘　　要：表面疲劳剥落是冷轧辊失效的主要形式之一,本文试图从轧辊的应力、硬度、组织形态等方面的综合分析出发,提出疲劳剥落失效机理的模型,并结合实例作了讨论。The surface fatigue spalling is one of the main reasons for cold-working rolls to be discarded. In this paper, a synthetical analysis is given out from the respect of stresses, hardness and metallography of the cold-working rolls, and a model of mechanism concerning the fatigue spalling is also proposed. At the same time, discussions are conducted with the typical examples.
