Optimization of Pulverized Coal Injection Control System in Blast Furnace
This paper discusses the optimization technology of the injection system for blast furnace in the domestic metallurgical industry,explains the working principle,process flow,con-trol equipment,instrument,monitoring parameters and protection measures of the blast furnace in-jection system,states the problems of the coal injection system,points out the problems of the injec-tion control system,carries out the optimization design of the control system,and describes the rea-sons for the fluctuation of the pulverized coal in the injection process.In combination with the actual problems of the injection system of a steel plant,an optimization and transformation scheme is pro-posed,which can effectively improve the powder loading efficiency of the injection tank,reduce the error of the pulverized coal injection rate,and improve the accuracy of pulverized coal injection.
