本文报告了高炉型渣中氧化钒还原的动力学研究及渣铁间硅-钒平衡研究的结果.根据实验结果讨论了渣中钒还原进入生铁的机理,同时也阐明了生产中总结出的影响钒收率诸因素的本质.在实验得到的钒还原规律的基础上,分析了高炉冶炼含钒铁矿的生产数据,证明在高炉中硅-钒反应尚未达到平衡,从而指出了提高钒收率及降低生铁中硅相对含量的途径。
This paper reports the kinetics of reduction of vanadium oxide in blast furnace slag and the results of the study on the balance of silicon and vanadium between slag and slag.According to the experimental results, the mechanism of vanadium reduction in slag into pig iron is discussed and the effects summarized in the production are also illustrated Vanadium recovery rate.According to the vanadium reduction rule obtained from the experiment, the production data of blast furnace smelting vanadium-bearing iron ore are analyzed to prove that the reaction of silicon-vanadium has not reached the equilibrium in the blast furnace, and the vanadium recovery rate And reducing the relative content of silicon in pig iron.
