Abstract
The sulphide capacities of CaO-MgO-Al2O3-SiO2-CrOx slags with were measured by gas-slag equilibration method in the temperature range of 1823-1898K to reveal the effect of CrOx on the sulphide capacities of slags. Both higher basicity and temperature enhanced sulphide capacities. The CrOx additions in the range of 0–5 mass% increased the sulphide capacity, but, further increase of CrOx contents to 7 % was found to lower the sulphide capacity. Utilizing the relationship for estimating the ratio of Cr2+/Cr3+put forward by the present authors, the influence of Cr(II) on the sulphide capacities of the slags studied is discussed.
