Abstract

"A sintering study has determined the sintering characteristics of a conventionally prepared charge and a pelletized charge. The conventional charge was prepared by tumbling the moist ingredients. The pelletized charge was prepared by coating the return sinter with a layer of new material in a pelletizing drum to form pellets. A laboratory batch sinter pot was used for all tests. The effects of several variables were investigated using both statistical and classical experimental designs. The independent variables which were investigated were proportion of returns, moisture content, air flow, bed height, size distribution of the returns, ignition time, and recycle of off gases. The dependent variables were sulfur elimination, sinter strength, production rate of sinter, permeability of the sinter bed, and bed temperature. The sinter properties of a conventionally prepared charge are strongly dependent on water content while the sinter properties of a pelletized charge are not strongly influenced by the independent variables except air flow and recycle of off gases. The production rate for both conventional and pelletized charges is proportional to the air flow. However, a pelletized charge gives higher sinter production rates and higher sinter quality. Recycle of off gas has a large deleterious effect on both sinter quality and sinter production rate. A dynamic computer model of the sintering process has been developed which partially describes the thermal and chemical response of the sintering process to a wide variety of sintering conditions"--Abstract, page ii.
