摘　　要：通过实验和热力学计算,低碱度(R_(2)=1.00)时高炉渣ω(MgO)/ω(Al_(2)O_(3))对熔化和流动性能影响进行了研究。结果发现:由于MgO和Al_(2)O_(3)的升高,炉渣固相状态改变,导致液相生成路径减少,造成炉渣的熔点和液相线温度升高,但炉渣的熔化性温度降低。碱度为1.00、ω(Al_(2)O_(3))=14%~16%时,随着渣中MgO含量的增加,炉渣粘度先增加后降低;ω(Al_(2)O_(3))=18%时,炉渣粘度值随着MgO含量的增加持续降低,并在ω(MgO)=10%时粘度值最低。Through experimental and thermodynamic calculations,the effects of blast furnace slag ω(MgO)/(Al_(2)O_(3))on melting and flow properties at low alkalinity(R_(2)=1.00)were studied.The results show that due to the increase of MgO and Al_(2)O_(3),the solid phase state of the slag changes,resulting in the decrease of the liquid phase formation path,resulting in the increase of the melting point and liquidus temperature of the slag,but the melting temperature of the slag decreases.When the alkalinity is 1.00,ω(Al_(2)O_(3))=14%~16%,with the increase of Mg0 content in the slag,the viscosity of the slag increases first and then decreases.When ω(Al_(2)O_(3))=18%,the viscosity value of slag decreases continuously with the increase of MgO content,and the viscosity value is the lowest when ω(MgO)=10%.
