Abstract

Experiments were made to examine the sulphur distribution between liquid iron and CaO-MgO-Al2O3-SiO2 (SiO2=020 wt%) slags in a magnesia crucible at the temperatures of 1 575, 1 600 and 1 650°C. The results showed that the transfer of sulphur between liquid iron and slag was slower than the dissolution of magnesia from the crucible into the slag. The main equations obtained in the present study are as follows:
logCS=3.44(NCaO+0.1NMgO-0.8NAl2O3 NSiO2)-9894/T+2.05
logLS=3.59(NCaO+0.1NMgO-0.8NAl2O3-NSiO2) -0.905logNFeO-4640/T+0.385
The validity and the applicability of these equations have been examined by comparison with the data of other investigators.
