| 摘 要： | 通过合理变化精轧各架的压下负荷分配,可在实现带钢良好凸度控制的同时,兼顾到平直度的控制。该方法考虑到带钢板形取决于下游机架轧制时金属的流动,同时平直度可通过末机架的轧制状态得以控制,其实质是通过改变精轧各架的压下负荷分配来补偿轧辊热凸度变化。文中列出3种压下模式,在保证比例凸度近乎常数的前提下,通过比较这几种模式下得到的计算凸度值和实际凸度值,来说明该方法可补偿轧辊热凸度变化对带钢板形的影响,具有实际的应用价值。 |

| Abstract: | The hot-rolled strip crown can be controlled through reasonable changes of reduction distribution along with the rolling progress,and the strip flatness can be controlled simultaneously.This method takes into consideration the fact that the strip profile is determined by metal flow in the latter stands,and the fact that the flatness can be controlled by the rolling condition at the final stand,the essential of this method is to compensate for the roll thermal crown change through changes of schedule distrib... |
