Research and practice on visual detection of foam degree of converter slag
By analyzing the problems existing in the existing single technology of converter smelting detection,the online quantitative evaluation technology of slag foam degree and the online prediction technology of process feature points of flue gas analysis are developed on the basis of summary to solve the problem of converter black box and realize converter smelting visualization.Based on the identification results of the detection technology,the intelligent intervention technology of powder spraying and slag suppression at the tapping port and the intelligent intervention technology of the ox-ygen gun are used to achieve stable control of the converter blowing process.After the application of technology,the risk of slag overflow during the converter smelting process is significantly reduced,preventing explosive splashing in the middle and later stages,and reducing the loss of metal materi-als.After the control of the converter smelting process is stabilized,it is beneficial to improve the end-point temperature and carbon prediction hit rate.
