摘　　要：在介绍山东泰山钢铁集团有限公司1 800 mm炉卷轧机设备特点的基础上,分析了带钢头尾厚度偏差形成的原因。针对这些原因,在工艺控制方法上采取了最小化头尾温降、改进头尾辊缝控制、温度补偿以及综合应用压力AGC和监控AGC等削减厚度偏差的相应措施,改进后使带钢头尾厚度公差大大减小。实践表明,带钢头尾厚度偏差的存在不是一个单纯设备问题或控制问题,而是一个综合性问题,需要在设备、生产工艺以及工艺控制等方面综合实施减小厚度公差的方法,才能取得很好效果。Abstract： This paper analyzed the reasons that head and tail thickness deviations occurred after dis- cussing the equipments features of 1 800 mm steckle mill in Shandong Taishan Iron and Steel Group Co., Ltd. Some steps on equipments, such as minimizing the head and tail temperature drop and im- proving the head and tail gap settings in technical control, and comprehensive application of pressure AGC and monitor AGC and so on, are taken to decrease the thickness tolerance, which reduced the head and tail thickness deviations of steckle mill. Practice indicated that the head and tail thickness deviation is not only a problem caused by the equipments or control, but a complex problem. It needs to combine the equipment, production technique, technical control and so on, to reduce the thickness deviations and obtain good effects.
