一种新的换辊管理模式在冷轧连退机组的应用

Application of a New Pattern of Roll Change Management in the Continuous Annealing Processing Line of Baosteel Cold Mill Plant

分析了宝钢冷轧连退机组的换辊管理模式存在的问题,通过在L2过程机中对现有管理模式进行改进,形成一套新的换辊管理模式。L2过程机自动保存轧辊实绩数据,实现轧辊实物和信息流同步;在L2过程机中保存的轧辊实绩数据能够允许操作人员反复使用;同时提供轧辊实绩数据的手动发送方式。新的换辊管理模式对提高轧辊使用率和确保机组稳定生产提供了帮助。

The existing problems of the roll change management in the continuous annealing processing line （CAPL） of Baosteel Cold Mill Plant were analyzed. With the improvement of the existing management mode for L2 process computer, a new roll change management mode has been formed. L2 process computer automatically stores all the data of the roll change results, and it helps achieve synchronization of the actual roll and its information. The data stored by L2 can be repeatedly used by operators, and the manual transmit mode of the roll change result can be also provided. The new roll change management mode is helpful for improving the roll＇ s activity ratio and for ensuring the line＇ s stable operation.
