依据承德建龙特殊钢有限公司当前的高炉冶炼情况,以钢厂渣为基准,利用黏度测试装置,分析了钒钛高炉渣的碱度、w(TiO_2)、w(MgO)对高炉渣黏度与熔化性温度的影响。研究结果表明:随高炉渣碱度提高,黏度和熔化性温度先降低,碱度继续提高到1.25时,炉渣黏度与熔化性温度迅速提高;随着高炉渣中w(TiO2)提高,黏度和熔化性温度呈先降低后升高的趋势;w(MgO)提高利于降低炉渣熔化性温度,不同w(MgO)情况下,炉渣熔化性温度最高为1297℃。碱度为1.15~1.20,w(TiO_2)小于10%,w(MgO)在12%~14%时,钒钛炉渣流动性较优。
According to the current blast furnace smelting situation of Chengde Jianlong Special Steel Co., Ltd., the basicity of steel mill slag and the viscosity test equipment were used to analyze the influence of basicity, w (TiO_2) and w (MgO) Effect of melting temperature. The results show that with the increase of basicity of blast furnace slag, the viscosity and melting temperature decrease first and the alkalinity continues to increase to 1.25. The viscosity and melting temperature of slag increase rapidly. With the increase of w (TiO2) in blast furnace slag, the viscosity and melting The temperature is the first to decrease and then increase. The increase of w (MgO) can reduce the melting temperature of slag, and the highest melting temperature of slag is 1297 ℃ under different conditions of w (MgO). The alkalinity is 1.15-1.20, the content of w (TiO 2) is less than 10% and the content of w (MgO) is 12% -14%.
