摘　　要：通过DEFORM-3D数值模拟软件,对105t Cr5锻钢支承辊锻坯进行了两种不同压下量工艺方案的数值模拟,对比分析了其对拔长过程中的损伤值和等效应变的不同影响,以及模拟了拔长后锻坯偏析带的分布状况,为今后的生产工艺改进提供更加合理的科学依据。The software DEFORM-3 D is used to perform numerical simulation for the two kinds of process schemes with different reduction amount for 105 t forging blank of Cr5 forged steel backup roll, and compare and analyze the in- fluence of the different processes on the damage value and equivalent strain during drawing, and simulate The distribu- tion situation of the segregation band of forging blank after drawing, which provide more reasonable scientific reference for the process improvement in future.
