摘要: 根据承钢高炉炉渣含钒高的特殊性,为了提高钒的还原收得率,研究高炉炉渣性质与钒还原的关系。研究结果表明:在炉渣碱度R12、MgO含量10%左右、Al2O3含量14%左右、TiO2含量9%以下、炉渣温度1 500℃左右条件下,有利于钒还原;增加渣中V2O5含量,炉渣熔化性温度降低,但对炉渣黏度影响不明显。Abstract: Due to high vanadium content in Chenggang blast furnace slag,in order to improve the reduc-tion rate of vanadium,the relationship between blast furnace slag properties and reduction of vanadium ox-ide was investigated in this paper The results show that when the combined conditions of basicity of slag R conrrolled at 1.2,~10% MgO,~14% Al2O3,less than 9% TiO2 content, and the slag temperature at about 1 500℃ are used,reduction of vanadium can be improved With the content of V2O5 increasing,the melting temperature of the slag decreases,but its effect on the viscosity of slag is not visible
