摘　　要：为了对轧辊断裂生产事故加强防范,笔者阐述了轧辊断裂机理,提出冷轧轧辊微裂纹形成以及断裂主要与轧辊承受的热应力、冲击应力、轧辊质量等因素有关,提出应通过规范工艺与科学制辊、定期保养与按时维护、规范操作与安全生产等措施防范冷轧轧辊断裂,指出只要规范管理,积极防范,轧辊断裂生产事故是完全可避免的。In order to prevent roll fracture accident,this paper expounds the fracture mechanism of roll,points out that microcrack and fracture of cold mill roll are mainly related to thermal stress,impact stress,roll quality and other factors.It puts forward that it is necessary to prevent cold mill roll fracture by standard process,regular maintenance and standard operation,and roll fracture accident is completely avoidable if active precautions are taken.
