摘要: 根据承钢高炉炉渣含钒高的特殊性,以现场渣为基准,研究了钒对炉渣黏度(η)、熔化性温度(Ts)和脱硫的影响。研究结果表明:随着V2O5含量的升高,炉渣呈短渣特性,炉渣黏度先升高后降低,炉渣熔化性温度持续降低。当温度高于熔化性温度时,适当增加V2O5含量,黏度降低,对生产有利。随着温度升高,炉渣黏度降低,温度越高,黏度变化越小。温度的升高有利于脱硫反应的进行,V2O5含量的变化对炉渣脱硫的影响不大。Abstract: Due to high vanadium content in Chenggang blast furnace slag,the influence of vanadium on properties of viscosity,melting temperature and desulfurization was investigated in this paper.The results show that when V2O5 content increases,the slag possesses short slag feature,slag viscosity increases to a certain value and then decreases,but the melting temperature continues decreasing,.When the tempera-ture is higher than the melting temperature,increasing V2O5 content leads to viscosity reduction,which is good for production.Slag viscosity decreases with the temperature increasing.The higher the temperature is,the smaller the viscosity difference.Increasing temperature accelerates the desulfurization reaction.V2O5 content of blast furnace slag has little effect on desulfurization.
