摘要
玉钢2号高炉上料控制系统在生产运行中，出现了启动后退、料车减速时变频器频繁跳闸等故障，并且存在料车冲顶的隐患，经调整相关控制参数和设备改造后，有效地解决了存在的问题和隐患。
During production process of charging system of No.2 blast furnace in Yugang,skip run back after starting,inverter tripped frequently when skip decelerated,and the skip might run up.By many control parameter changed and epuipment modified,the question was slolved
