Abstract
Liquid iron at 1600 degrees C, containing 0.088 wt% S and 0.070 wt% O, was desulphurized by a lime-saturated calcium ferrite slag at a rate significantly greater than that calculated on the assumption that diff usion of sulphur in the liquid iron was rate controlling. It is postul ated that the transfer of sulphur across the slag-metal interface caus ed local variations in the interfacial Energy, which induced Marangoni stirring in both the metal and slag phases.
