,the control on MgO content and binary basicity under different cotents of Al_2O_3 in slag are studied through theory study and production practice analysis and the reasonable range of slag content is presented.
为保证首钢高炉长期稳定运行,通过理论研究与生产实践分析,对炉渣中三氧化二铝不同含量下的氧化镁含量及二元碱度控制进行了研究,提出了炉渣合理的控制范围。
Some factors to influence the silicon content of hot metal were proposed on the basis of the experiment in the lab: increasing the binary basicity is favorable to desiliconization;the oxide in slag debases the silicon activity and is of great advantage to desiliconization;Al2O3 and SiO2 are disadvantageous to desilic.
在实验室进行了降低铁水中硅含量的实验,得到了铁水中硅含量的影响因素:提高二元碱度有利于降硅;增加渣中氧化物可降低SiO2的活度有利于降硅;Al2O3和SiO2不利于降硅;冶炼时焦炭中SiO2的挥发量随温度的升高而增多,使铁水中硅含量增加;随着滴落带高度的增加,铁水中硅含量不断增加。
