以承钢现场渣为基准，研究了钛、镁、铝对炉渣黏度、熔化性温度和脱硫的影响。研究结果表明：在CaO-Al2O3-SiO2-MgO-TiO2五元渣系中，钛、镁、铝对炉渣性能的影响较大。随着MgO质量分数增加，熔化性温度先降低后升高，黏度呈降低趋势，脱硫能力先升高后降低；随着Al2O3质量分数的增加，熔化性温度先降低后升高，黏度变化复杂，脱硫能力降低；随着TiO2质量分数的增加，熔化性温度和黏度呈升高趋势，而脱硫能力降低。当炉渣碱度为1.12时，炉渣适宜成分：MgO质量分数约为13.95%，Al2O3质量分数约为13.75%，TiO2质量分数控制在10.57%以下。合理控制炉渣中钛、镁、铝的配比，对改善炉渣性能和提高高炉生产有重要意义。
According to the spot slag of Chenggang,the influence of Ti,Mg and Al on properties,such as viscosity, melting temperature and desulfurization were investigated. The results show that Ti,Mg and Al had a large effect on the properties of slag in the CaO-Al2O3-SiO2-MgO-TiO2 slag system. With the content of MgO increasing,melting tempera-ture decreased and then rised,viscosity decreased and desulfurization rised and then decreased. With the content of Al2O3 increasing,melting temperature rised and then decreased,the change of viscosity was complicated and desulfurization de-creased. With the content of TiO2 increasing,melting temperature and viscosity tended to rise,and desulfurization was de-creased. When the basicity of slag was 1.12,the suitable slag composition was that the content of MgO was about 13.95%,the content of Al2O3 was about 13.75%,the content of TiO2 was below 10.57%. The ratio of Ti,Mg and Al in slag is reasonable controlled,which is conducive to perfecting the property of slag and improving the production of blast furnace.
