Finite Element Analysis of Tracked Steel’s Rolling Process
-
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。Abstract: 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.
