Abstract

See full text

The present invention provides a method for producing a granular metallic iron in which an adhesion inhibitor leveler, an agglomerate leveler, a discharger, and the physical state of materials present on the hearth are optimized to thereby enable agglomerate to be spread in a single layer. The agglomerate hence is evenly heat-treated to enable high-quality granular metallic iron to be produced in satisfactory yield.
