In order to utilize the zinc-iron resources rich in the bag ash of a steel mill's electric furnace, the reaction rate and degree of zinc ferrite in the solid-solid reduction reaction are analyzed from the kinetic point of view. The results show that in the process of reduction of zinc and iron in the bag ash of electric furnace, the weight loss rate and dezincification rate are positively correlated with the increase of reduction temperature and reduction time within a certain range. The reduction temperature of 1300 ℃ was determined, and the reduction rate of zinc in the electric bag ash was 98% when the reduction time was 15 min. The research on the kinetics of reductive dezincification shows that the ratio of decarburization with fixed carbon proportions is relatively fast. At this time, the dezincification rate can reach more than 90%.
