富氧顶吹熔融还原炼铁工艺与实践
|
摘要
熔融还原炼铁技术能解决焦煤匮乏和环境污染两大难题,已成为炼铁发展的主要研究方向。通过富氧顶吹熔融还原高磷铁矿的试验,证明了利用氧气顶吹熔融还原技术冶炼高磷矿是可行的,并且在适宜的冶炼条件下,铁的收得率最高可以达到95%。在富氧顶吹熔融还原冶炼过程中随着还原温度的升高,铁的收得率和金属化率相应的提高,当熔炼温度在1600℃时,金属化率可达95.16%,铁矿粉中的铁元素被还原较为彻底。同时随温度升高生铁碳含量增加。
Smelting reduction ironmaking 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 in appropriate smelting conditions, the iron recovery rate can reach at 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, when it's at 1600 ℃, the iron yield would be at 95.16%.
