Experimental Determination of Sulphide Capacities of Blast Furnace Slags with Higher MgO Contents.

Sulfide capacity measurements of slag with MgO content up to 18 mass% were carried out at 1713, 1743 and 1773 K to obtain reliable data for the blast furnace process. In the measurement, slag is equilibrated with copper at controlled oxygen partial pressure for 24h. The sulfide capacities are calculated based on the sulfur analyses for both slag and copper.
