摘　　要：简单介绍了宝钢集团上海梅山钢铁股份有限公司1422mm热连轧机针对轧制扰动引起的动态速降所采取的预补偿技术和实现,通过对1422mm热连轧机现状和现有动态速降预补偿技术效果的分析,提出了动态速降双补偿技术控制策略,即在原有预补偿技术的基础上再增加实时的动态速降补偿。在梅钢热连轧机组实际应用后表明,该技术对减小轧制扰动引起的动态速降效果明显。Precompensation technology for dynamic speed drop which was caused by rolling disturbance in Meisteel Hot Rolling Plant is introduced.By study of mill status and effect of precompensation technology,a double compensation control strategy for dynamic speed drop is presented.It is the method that realtime compensation was added to exiting precompensation.After the double compensation technology was applied to hot rolling mill of Meisteel,dynamic speed drop was reduced obviously.
