摘　　要：针对首钢冷轧单机架四辊平整机平整液残留问题,分析了平整机平整液系统和吹扫系统的特点,通过采取提高吹扫压力、增加喷梁、缩短可能残存平整液管路长度等措施,有效解决了平整液残留问题,大大提高了罩退产品质量,合格率由20%上升到90%。In view of the problem of the emulsion residual on the strip surface of the single stand temper mill,the characteristics of emulsion system and airflow system were analyzed.Therefore,some measures had been adopted,such as increasing airflow pressure,adding spray beam,shortening the length of emulsion pipe,and so on.Practical production shows that the problem is efficiently resolved,and the product quality is obviously improved.The product pass rate is increased from 20％ to 90％.
