The goals of this investigation were to analyze the reasons for the short service life of the lining of an ore-roasting furnace used to roast argillites and to determine the mechanism responsible for wear of the lining. The new design developed for the electric furnace based on the results from the analysis has ensured safe operation of the furnace, increased the value of the time-based utilization factor (from 0.33 to 0.73), increased the size of the charge that can be processed, decreased the number of repairs, and reduced electric-power consumption. The service life of the lining has increased from three to 16 months. A similar lining that includes carbon blocks in the furnace bottom has been installed in an electric furnace used to make lead at the Leningrad Polymetallurgical Combine.
