説明
A new sintering process was proposed which may cope with the increase in the ratio of fine iron ores. The basic concept associated with the new process using double layered mini-pellets (named duplex mini-pellets) was presented. The sintering experiments were conducted by using duplex mini-pellets and the quality of the produced sinter was evaluated by the various physical tests.<BR>(1) Excellent permeability was observed for the sintering bed using the duplex mini-pellets compared with that for the current sinter practice.The bed-permeation resistance was reduced because size and structure of the pellets remained unchanged in the course of sintering before the fusion.<BR>(2) By selecting the low melting region in CaO-Fe2O3 phase diagram as the chemical composition of the shell layer fines (CaO 20 wt%, Fe2O3 80 wt%), the sintering of the duplex mini-pellets was achieved at low temperature around 1230°C.<BR>(3) The sinter produced by the method mentioned above had the texture of primary hematite and binary calciumferrite without secondary hematite.<BR>(4) The sinter having such texture had excellent metallurgical properties, that is to say, low RDI, high JIS RI and good softening and melt-down properties.
