Reduction of Acid Iron Ore Pellets under Simulated Wall and Center Conditions in a Blast Furnace Shaft

The operational conditions, including temperature and gas composition, vary along the radial position in a blast furnace. Nevertheless, very few studies can be found literature that discuss how reduction behavior of ferrous burden varies position. In this study, effect charging on reducibility acid iron ore pellets was investigated using laboratory-scale, high-temperature furnace CO-CO2-N2 CO-CO2-H2-H2O-N2 atmospheres up to 1100 °C. experimental conditions were accumulated based earlier measurements from multi-point vertical probing campaign performed for center-working European main finding study is pellet proceeded faster under simulated resembling those center area, compared wall because higher share CO H2 gas. Therefore, affects its path Additionally, it shown presence H2O reducing enhanced progress reactions significantly formation cracks slightly, both which are desirable operation. data attained important understanding composition connected degree realistic process conditions.
