一、引言为完善现场轧制工艺、确保设备安全和提高产品质量,需要进行轧制负荷的测试与研究。特别是其中的2~#轧机(现场称2道车),由于系利用四辊轧机的废工作辊改做成二辊轧机使用,除以前有过断辊现象外,其本身还存在着先天性的缺点,如细长比大 I. INTRODUCTION In order to improve the on-site rolling process, ensure the safety of equipment and improve the product quality, the rolling load test and research are required. Especially the 2 ~ # rolling mill (on-site called 2 cars), because the Department of the use of four-roll mill waste work roll into a two-roll mill to use, in addition to the previous off the phenomenon of the roller, which itself is still congenital The shortcomings, such as slender than large
