摘要
通过对导辊的工作状况、导辊材料、热疲劳等因素的分析，找出了导辊裂纹产生的原因是：材料热物理性能偏低，以及导辊制造过程中所存在的缺陷。提出消除裂纹的方法是：提高导辊材料的导热性和严格控制导辊生产质量。
Working condition of guide roll,material and
heat fatigue of guide roll etc were analysed Reasons of occuring crack on guide roll were found
These reasons were that heat physical property of guide roll material was bad,guide roll had
failing Ways of clearing crack away was found These ways were improvement of thermal
conductivity of guide roll material,amelioration of guide roll quality and heat treat for guide roll
