Abstract :
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. From the test results, dephosphorization is more appropriate for the temperature range 1500-1550°C, the temperature can meet the mobility of iron slag, but also to meet the needs of dephosphorization, With the increase of basicity, lower phosphorus content of hot metal, when the alkalinity of 2.5, the iron content of 0.11% phosphorus, hot metal in the P content increased with increasing concentration of top-blown oxygen showed a rapid decline.
