摘　　要：履带钢断面形状复杂,轧制过程中容易出现扭转、翘曲、侧弯等现象,影响轧制的顺行。利用仿真软件建立了履带钢切深孔轧制过程有限元仿真模型,研究孔型参数对轧件扭转、翘曲及侧弯的影响规律。针对履带钢切深孔轧制扭转严重的问题,优化孔型参数,使履带钢切深孔轧制过程扭转角从135.6°减小到13.85,°满足后续道次正常咬入的要求,保证了生产的顺利进行。The tracked steel＇ s section is very complex. The phenomena of torsion and warpage often happen, which affects the tracked steel＇ s rolling process. The finite element model of tracked steel＇ s rolling process in the knifing pass was established. The influences of the pass parameters upon the rolled piece＇ s torsion and warpage were studied. On the basis, the pass parameters were optimized. The study made the torsion angle reduce from 135.6° to 13.85°, which ensured the succeeding pass rolling processes.
