马钢板坯连铸漏钢预报技术的进展

Progress in the Prediction System of Preeckout in the Masteel

马钢四钢轧BPS系统开发基于10多年前的思想理念,在使用性和报警的准确性上已逐渐难以满足现场高拉速多钢种的需求,致使发生多次漏报、频繁误报。改造后的漏钢预报系统经过4个月的测试,误报率降低高达93.26%,漏报为0,其在提高连铸机的产能、改善铸坯质量、减少漏钢事故等方面发挥极其重要的作用。

No. 4 Steelmaking and Rolling Gennal Plant of Maanshan BPS system developmentconcept based on the thought of more than 10 years ago, on the accuracy has been more difficult to satisfy the high speed steel demand which happens repeatedly omission andfrequent false positives. After transforming the breakout prediction system , b y 4 monthsrate of false positives to reduce as much as 93. 26%,omission of 0 ,its capacity in ous casting machine,the improvement of slab quality and decrease breakout accident are playing ex-tremely important role.
