Abstract

Excellent permeability was observed for the sintering bed using duplex mini-pellets compared with current sinter practice. The bed-permeation resistance was reduced because size and structure of the pellets remained unchanged in the course of sintering before fusion. By selecting the low melting region in the CaO-Fe//2O//3 phase diagram as the chemical composition of the shell layer fines (CaO 20 wt%, Fe//2O//3 80 wt%), sintering was achieved at temperatures around 1230 degree C. The sinter had the texture of primary hematite and binary calcium ferrite without secondary hematite. The sinter had excellent metallurgical properties.
