采用气渣平衡法测定了高铝高炉炉渣的硫化容量。本研究考虑了两种不同的渣体系，即cao - sio2 - mgo - al2o3季系和cao - sio2 - mgo - al2o3 - tio2五系。用ar - co - co2 - so2混合气平衡渣液。实验温度范围为1773 ~ 1873 K。研究了炉渣温度、碱度、MgO和tio2含量对硫化容量的影响。正如预期的那样，硫化物容量随着温度和碱度的增加而增加。在较高的实验温度下，钛降低了炉渣的硫化物容量。而在较低温度下，二氧化钛对炉渣硫化物容量的影响不显著。当MgO含量大于5%时，硫化物容量随矿渣中MgO含量的增加而增加。
Sulfide capacities of high alumina blast furnace slags were experimentally determined using the gas-slag equilibration technique. Two different slag systems were considered for the current study, namely, CaO-SiO2-MgO-Al2O3quaternary and CaO-SiO2-MgO-Al2O3-TiO2quinary system. The liquid slag was equilibrated with the Ar-CO-CO2-SO2gas mixture. Experiments were conducted in the temperature range of 1773 to 1873 K. The effects of temperature, basicity, and the MgO and TiO2contents of slags on sulfide capacity were studied. As expected, sulfide capacity was found to increase with the increase in temperature and basicity. At the higher experimental temperature, titania decreases the sulfide capacity of slag. However, at the lower temperature, there was no significant effect of titania on the sulfide capacity of slag. Sulfide capacity increases with the increase in MgO content of slag if the MgO content is more than 5 pct.
