摘　　要：文章对凌钢现场高炉渣进行取样,分析其化学成分和矿物组成。通过粘度实验研究了MgO、Al_(2)O_(3)、TiO_(2)含量对炉渣粘度及熔化性温度的影响,并利用FactSage8.1软件分析了不同成分对炉渣过热度的影响规律。从炉渣粘度、熔化性温度及过热度角度综合分析,建议凌钢高炉炉渣MgO含量控制在8.2%~9.6%,Al_(2)O_(3)含量控制在14.4%~15.8%,TiO_(2)控制在5.6%左右。The chemical composition and mineral composition of the blast furnace slag in Lingsteel were analyzed by sampling.The influence of MgO,Al_(2)O_(3)and TiO_(2)on slag viscosity and melting temperature was studied by viscosity experiment,and the influence of different components on slag superheat was analyzed by FactSage8.1 software.From the perspective of slag viscosity,melting temperature and superheat,it is recommended that the content of MgO,Al_(2)O_(3)and TiO_(2)should be controlled within 8.2%~9.6%,14.4%~15.8%and 5.6%.
