摘要: 在实验室条件下,以国内某钢铁企业提供的钒钛磁铁矿现场高炉渣为基础,利用纯化学试剂调整炉渣成分,采用RTW熔体物性测定仪进行了5因素4水平的正交试验研究,检测了炉渣冶金性能;然后运用综合加权评分法对试验结果进行分析,探索得出高炉冶炼钒钛磁铁矿的适宜渣系:二元碱度R2115,MgO质量分数14%,Al2O3质量分数13%,TiO2质量分数7%,V2O5质量分数020%.对渣系综合指标影响从大到小依次为:V2O5含量,MgO含量,二元碱度R2,TiO2含量,Al2O3含量.

Abstract: The components of practical blast furnace(BF) slag of vanadiumtitanium magnetite provided by a domestic enterprise were adjusted by adding pure chemical reagents under laboratory conditions, then the five factors in four levels orthogonal experiment was carried out and the metallurgical properties of slag samples were investigated using RTW melt property tester. Finally, through the comprehensive weighted scoring method, the suitable BF slag system for smelting vanadiumtitanium magnetite was obtained as follows: binary basicity was 115, the content of MgO, Al2O3, TiO2 and V2O5 was 14%, 13%, 7% and 020%,respectively. Besides, the order of each factor affecting comprehensive indexes of slag system was the V2O5 content, MgO content, binary basicity, TiO2 content and Al2O3 content.

Key words: vanadiumtitanium magnetite, slag metallurgical property, slag system optimization, orthogonal experiment, comprehensive weighted scoring method
