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、Al_2O_3含量14%左右、TiO_2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V_2O_5含量,炉渣熔化性温度降低,但对炉渣黏度影响不明显。
Due to high vanadium content in Chenggang blast furnace slag, in order to improve the reduction rate of vanadium, the relationship between blast furnace slag properties and reduction of vanadium oxide 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.
