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.
