LF专家系统在精炼系统中的应用

LF专家系统以Oracle10g数据库为核心,通过OPC采集现场PLC数据、化验室数据和企业管理级生产调度数据;经过数据库内存储过程处理的数据,通过Delphi编辑的界面进行人机交互。功能模型包括吹氩搅拌、造渣脱硫计算、温度预测、合金计算等模型。专家系统应用后,运行稳定可靠,主要事件正确判断率可达90%以上,进一步提高了LF精炼炉的精炼水平,简化和规范了生产流程。

Application of LF Expert System in Refining System

LF expert system takes Oracle 10g database as core, the I＇LL data, laboratory data, enterprises management anu mspatcner data are adopted by OPC in the field; the man-machine interaction is made by edited interface by Delphi for treated data in database; the main function model is consisted of blasting argon stirring, slagging and desulfurization accounting, predicting temperature and alloying accounting models. After using the expert system, stable and reliable operation is achieved, the judgment rate of main event is up to above 90%, the refining level of LF refining furnace is further increased and the production process is sirnphfied.
