摘　　要：为探究回火温度和时间对锯片基体强度、硬度及变形的影响,利用非稳态导热原理,建立了锯片基体码垛加压回火过程的温度场数值模型,模拟不同回火条件下的温度场分布,并分析其对轴向和径向变形的影响。研究发现,加压回火中锯片基体垛的径向和轴向最大温差分别约为10℃和(18~20)℃,65Mn锯片基体码垛用钢最佳回火工艺为400℃下保温12 h。通过数值模拟与实验数据对比,验证了回火变形规律与温度分布特性的一致性。Aiming at the effects of tempering temperature and duration on the strength,Utilizing the principles of unsteady-state heat conduction,a numerical model of the temperature field during the stack tempering process of saw blade bases under pressure was established.The model simulates the temperature field distribution under different tempering conditions and analyzes its impact on axial and radial deformation.The research reveals that the maximum radial and axial temperature differences in the stack during pressurized tempering are approximately 10℃ and 18~20℃,respectively.For 65Mn steel used in stacked saw blade bases,the optimal tempering process is identified as maintaining a temperature of 400℃ for 12 hours.The consistency between the deformation patterns and the characteristics of temperature distribution revealed by numerical simulation was validated against experimental data.
