Research and application of furnace condition monitoring and evaluation method of blast furnace

Large number of monitoring data of blast furnace need to be analyzed and processed where valuable data can be extracted in order to guide producing now. As a result,a blast furnace condition parameter monitoring and evaluation system was developed. According to the blast furnace process, two levels of rule bases were established individually,which monitored blast furnace parameters' variations and fluctuations,then evaluated blast furnace process status. Blast furnace operation and guide base was collected and created,by searching the base,guidance for operating blast furnace was formed. After it being put into practice,the goals of decreasing furnace fluctuation and energy consumption,and improving production efficiency of blast furnace were achieved.
