Smelting reduction iron making technology will solve the coke shortage and environmental pollution, which has become a major research of. Iron development. By oxygen top-blown high-phosphorus iron ore smelting reduction test, that the use of oxygen top-blown molten high phosphate smelting reduction technology is feasible, and inappropriate smelting conditions, the iron recovery rate can reach 95%. Reduction in the oxygen top-blown molten smelting reduction process with the temperature increased, the iron yield and the corresponding increase in the rate of metal-based, but with the increased alkalinity of pig iron and metal production rate has dropped, the same time as the reduction time extension of pig iron and metal production rate decreased.
