摘　　要：从宝钢分公司热轧厂2050mm热轧精轧压下组成部分分析出发,结合精轧机械压下和液压压下辊缝设定的原理,同时针对压下辊缝出错的现象,通过分析研究及相关论证找出影响压下辊缝出错的原因,系支撑辊平衡和弯辊力等外力的作用引起压下系统辊缝设定出错,最终通过程序优化解决精轧变规格辊缝设定不到位的问题,解决了由于支撑辊平衡和弯辊力引起的困扰精轧多年的压下辊缝出错故障,提高了精轧辊缝设定的稳定性,保证了正常的生产。Causes that lead to errors of screwdown roll gap have been found out through analyzing finish rolling screwdown components of the 2050mm mill in Hot Strip Rolling Plant, Baosteel Branch. It is the external force＇ s action, such as backup roll＇ s balancing and roll bending force that cause the roll gap setting error in the screwdown system. Finally through analysis and investigation, the error was corrected by optimizing the program. It improved the stability of the gap set for finish rolling, and guaranteed normal production.
