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。
Initial production, Panzhihua Iron and Steel 2 # slab caster mold forecast accuracy of only 10%, the main reason for the high false positive rate is the mold breakout alarm and stick steel alarm part of the parameters set unreasonable, the sensitivity is too high Caused. By adjusting some parameters of temperature changes in breakout prediction, selecting mold powder with good performance, standardizing operation and other measures, the accuracy of breakout prediction has been greatly improved by 80% and the false negative rate is zero.
