In this report the behavior of sulphur in the molten phase was studied. The amount of sulphur which transferred to slag from steel bath during melting period seemed somewhat to be influenced by the basicity of slag at the earlier period of melting period and at "melt down". Some investigations were made upon the influence of sulphur in iron ore or lime, the fluidity of slag and the "slag off" on the behavior of sulphur in steel bath during refining period. The fluidity of slag seemed to have a decided influence on the change of sulphur pct. in steel bath. The change of sulphur pct. in the ladle was studied. The relation between sulphur partition (S)/[S] and the basicity, and besides between [S] and the fluidity of slag was studied. The desulphurization action in the open hearth furnace seemed to proceed mainly by sulphur transfer between slag and bath or diffusion of sulphur in slag rather than by desulphurization reaction.
