摘要
研究了含碳铬矿团块在高温还原过程中影响Cr23还原的主要因素,以及含碳铬矿团块在高温还原过程中金属相的聚集长大及其与渣相的分离状态.研究发现:当含碳铬矿团块的渣相碱度达到1.6,还原温度为1400～1500℃时,可以实现还原产物中金属相与渣相完全分离;提高含碳铬矿团块的内配碳比可提高Cr23还原率,但不利于还原过程中金属相的聚集长大.
The main factors of affecting the reduction of Cr2O3 in synthetic chromite briquette by carbon at high temperature, and the condensation, growth and separating behavior of metal phase from slag phase during reduction at high temperature reduction have been researched. It's found that separating the metal from slag totally of synthetic chromite briquette by carbon after reduction at temperature 1400℃ to 1500℃ was highly possible if the basicity of slagmaking components of synthetic chromite briquette by carbon wasn't less than 1.6. Raising the C/O mole ratio of synthetic chromite briquette by carbon could raise the reductivity of Cr2O3, but be disadvantage for metal phase to condense and growth during reduction of synthetic chromite briquette by carbon.
