摘    要：对结晶器铜板热电偶温度的4种不同信号模式进行了分析,发现应用模式下不同温度信号模式在传播速度和变化趋势上存在明显的差异。针对目前国内引进的板坯漏钢预报系统因无法调整其预报参数而造成的高漏报、误报率,利用VC++编程语言开发了可调整预报参数并可显示热相图的逻辑漏钢预报系统,并利用国内某厂的实际生产数据进行了实验。实验结果表明:该系统运行稳定,能够更有效地对浇铸过程中的漏钢事故和铸坯有关表面缺陷进行预报。

Abstract: With analysis of four temperature signal modes,remarkable differences between temperature variation trend and spreading speed of different modes were found.For existing imported slab leakage prediction system,there are high failing and missing rates because prediction parameters can not be modified.Based on VC++ programming language,a new logic leakage prediction system was developed,and in the system,prediction parameters can be modified and hot phase diagram can be displayed.The system has been tested by use of practical data in a certain plant.Results show that the system runs steadily,and possible leakage and related slab surface defects in casting process can be predicted effectively.
