摘　　要：对粗轧机上支承辊平衡状态进行了计算分析,找出了上支承辊平衡状态不稳定的根本原因,并对平衡液压回路进行了优化,实施后大大改善了上支承辊的平衡状态,同时提高了上支承辊油膜轴承及平衡油缸的使用寿命。The calculation and analysis of the balance state of the upper supporting roll of roughing mill are carried out.The root cause of the instability of the balance state of the upper supporting roll is found out,and the balance hydraulic circuit is optimized.After the implementation,the balance state of the upper supporting roll is greatly improved,and the service life of the oil film bearing and the balance cylinder of the upper supporting roll is improved.
