【Abstract】 This paper analyzes the formation mechanism of the problem of "sticking, blockage and jamming" in alumina feeding, and believes that the improper control of superheat is the core reason for the problem of "sticking, blocking and jamming". This paper explores the impact of intelligent crust breaking and feeding technology on the material blockage, sticking, alumina concentration distribution, anode current distribution, pot cavity, effect and production indicators through data analysis. The results show that the combination of intelligent crust breaking and feeding technology together with the pot control system can reduce the problem of "sticking, blockage and jamming", homogenize alumina concentration, anode current distribution and ledge thickness, reduce the anode effect coefficient, improve current efficiency and save energy consumption.更多还原
