Determination of the optimal composition of iron ore materials for a liquid-phase reduction reactor
摘要
This study presents the results of an investigation into liquid-phase iron reduction technology. The goal of this technology is to improve the energy efficiency and environmental sustainability of metallurgical production. The primary objective was to determine the optimal composition of iron ore materials and the key parameters of the reduction process in order to minimize energy consumption and harmful emissions. Our methodology incorporated experimental tests in a Tammann furnace, thermodynamic calculations using the IVTANTHERMO software package, and mathematical modeling of the reduction process. Our findings suggest that an iron concentration of 53% in the raw material achieves a reduction degree of up to 99%. The study determined that the CO2 emissions associated with liquid-phase reduction are 0.95 tons per ton of product. This figure is 1.6 times lower than the emissions associated with sinter-coke blast furnace technology and 1.3 times lower than the emissions associated with the MIDREX process. This work defines the optimal parameters for the reduction process and demonstrates a substantial reduction in the carbon footprint achievable with the developed technology. The potential for industrial implementation of this technology underscores the practical significance of the research. This technology can be used to produce high-quality iron-containing materials. It has minimal resource consumption and atmospheric emissions.
