Abstract

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, $CaO-SiO_2-MgO-Al_2O_3$ quaternary and $CaO-SiO_2-MgO-Al_2O_3-TiO_2$ quinary system. The liquid slag was equilibrated with the $Ar-CO-CO_2-SO_2$ gas mixture. Experiments were conducted in the temperature range of 1773 to 1873 K. The effects of temperature, basicity, and the MgO and $TiO_2$ contents 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
