Blast furnace evaluation monitoring system based on FA-KM-SPC
The blast furnace,as a pivotal link in steel production,is crucial for production efficiency and product quality through its stable operation.Therefore,it is especially necessary to monitor and evaluate the operation status of the blast furnace in a timely and comprehensive manner.According to the historical production data of blast fur-naces,based on various methods such as factor analysis,K-means cluster analysis,and statistical process control(SPC),a set of software systems that could comprehensively evaluate and monitor the operation status of blast fur-naces was developed using computer technology,information technology,database technology,etc.Firstly,the production data was preprocessed to ensure the completeness and accuracy of the data.Then,according to the expe-rience of experts and the characteristics of blast furnace operation,29 key parameters were screened out for the con-struction of the evaluation model.After that,factor analysis and K-means cluster analysis were combined to estab-lish the evaluation model of the blast furnace status,and the key indexes that could comprehensively reflect the oper-ation status of the blast furnace were extracted to establish a comprehensive evaluation system of the blast furnace operation status.K-means cluster analysis was applied to classify and judge the blast furnace operation state,and the results were verified.Then,the SPC control chart realized the abnormal monitoring of the blast furnace opera-tion status and evaluation indexes and traced the reasons for the abnormal operation,which helps the operators ad-just the production strategy in time to ensure the continuous and stable operation of the blast furnace.Finally,based on the above model,the development of the blast furnace evaluation and monitoring system was completed,realizing the visualization of the blast furnace operation status,which effectively assists the operators in monitoring and man-aging the blast furnace operation and helps achieve the goals of high quality,low energy consumption,high produc-tion,high efficiency,and long service life in blast furnace production.
