摘　　要：为了掌握十二辊轧机中间辊横移量对带钢板形的影响规律,运用ANSYS/LS-DYNA显示动力学有限元软件,对十二辊轧机轧制不同宽度的304奥氏体不锈钢带进行中间辊横移控制的数值模拟。研究了当中间辊沿操作侧进行-30^-50 mm横向移动及带钢宽度变化时,工作辊有载辊缝和带钢应变曲线的变化情况。结果表明,动态调节中间辊横移量使对中长度L占来料宽度的55%~60%,可以获得平直度高的板形。In order to determine the effect of the intermediate roll shifting on the strip flatness,the dynamic software ANSYS/LS- DYNA was adopted to simulate intermediate roll control for rolling 304 stainless steel with different widths on twelve-high rolling mill. The loaded gap of work rolls and the strain distribution curve of the 304 stainless steel were calculated when the amount of intermediate roll shifting ranges from-30 mm to-50 mm. The results show that strip shape with good flatness can be obtained by dynamically adjusting the amount of intermediate roll shifting to make the value of length＂ L ＂to be 55%-60% of the initial width of strip.
