PRODUCTION METHOD OF GRANULAR METALLIC IRON

摘要

This method is for producing granular metallic iron in which the relation between the mass ratio (mass%) of the volatile matter content contained in a carbonaceous reducing agent and the average gas flow rate (m/s) of the ambient gas in a heating furnace fulfills expression (1). Mass ratio of volatile matter content ≦ -4.62 × average gas flow rate + 46.7 … (1)
