摘　　要：利用ANSYS Workbench对高铬钢辊环进行建模,模拟辊环离心浇注、凝固冷却和淬火热处理过程,通过有限元热分析计算出离心时辊环每层的离心时间和内表面温度,进而确定层与层之间的浇注间隔时间。模拟求解出辊环喷淬热处理时的温度场分布、淬透层温度和对应的表面温度,得出当淬透层深度的温度降低到工艺要求的时间即为喷淬时间,喷淬时可根据辊环表面温度来监测淬透层温度。通过有限元热应力耦合分析计算辊环凝固冷却后产生的应力值,结果表明,外层二次浇注相对外层一次浇注的应力值显著减小。The ANSYS Workbench has been used to establish the model of high-chromium steel roll rings and simulate the process of roll ring centrifugal casting,solidification cooling and quenching heat treatment.Through the finite element thermal analysis,the centrifugation time and inner surface temperature of each layer of the roll ring during centrifugation have been calculated,furthermore,the pouring interval between layers has been determined.The temperature field distribution,the temperature of the hardened layer and the corresponding surface temperature during the spray heat treatment of the roll ring have been simulated and solved,and the time when the temperature of the depth of the hardened layer is reduced to the process requirement is the spray quenching time.The temperature of the hardened layer has been monitored according to the surface temperature of the roll ring during spray quenching.The stress value generated after the solidification and cooling of the roll ring has been calculated by use of the finite element thermal stress coupling analysis.The results show that the stress value of the secondary casting of the outer layer has been significantly reduced by comparing with the primary casting of the outer layer.
