摘　　要：以Cr5支承辊为研究对象,通过测量表淬过程中的实测温度场,并基于实测温度场对表淬过程中的数值模拟参数优化后,利用数值模拟的方法研究了表淬工艺参数(预热温度、升温速度、冷却速度等)对支承辊工作层硬度降的影响,为Cr5支承辊在实际生产中减小工作层硬度降提供了一种解决思路。Taking Cr5 backup roll as the research object,by measuring the temperature field in the surface quenching process,and optimizing the numerical simulation parameters in the surface quenching process based on the measured temperature field,the effect of surface quenching process parameters(preheating temperature,heating rate,cooling rate,etc.)on the hardness drop of the working layer of the backup roll has been studied by numerical simulation method,which provided a guideline for reducing the hardness drop of the working layer of the Cr5 backup roll in actual production.
