Abstract:Huimin high-phosphorus iron ore and ilmenite from Yunnan province was smelted by oxygen enriched top-blown smelting reduction iron-making technology. Much more details, such as iron recovery rate, distribution ratio of phosphorus and sulfur were discussed. Iron recovery could reach 95% with phosphorus content about 0.32%, sulfur content 0.054% and titanium content 0.031% in pig iron produced, under the conditions of 20min holding time at 1500K, basicity R of 1.3, C/O mole ratio of 1.0 and oxygen enriched flow rate of 250L/h and ore blending ratio of 1∶1. Oxidizing potential of top-space of SRV and slag combination can create the driving force to partition phosphorous and titanium to the slag, which ensure the success of the experiment.
