结晶器漏钢预报在攀钢2号板坯连铸机上的运用

Application of mould breakout prediction system on No.2 slab caster of Panzhihua steel

投产初期,攀钢2号板坯连铸机结晶器漏钢预报准确率只有10％左右,误报率高的主要原因是结晶器漏钢报警和粘钢报警部分参数设置不合理,灵敏度太高造成的。通过调整漏钢预报部分温度变化参数,选择性能良好的结晶器保护渣,规范操作等措施,目前漏钢预报准确率已大干80％,漏报率为零。

At first, the accuracy of the mould breakout prediction system in Panzhihua Steel was only about 10%. The main reasons are that the parameters of breakout and sticking alarming are not reasonable due to its higher sensitivity. At present, the accuracy has been more than 80% without any breakout through regulating the temperature variable of breakout prediction, selecting the mould powder with good performance and standard operation.
