It was found that during desulphurization both the distribution con-stant of S along metal-slag interface, L_S~*, and distribation index inside the bulk,L'_S, vary with the descending of oxygen potential along metal-slag interface. Butthe plot of L_S~* vs time is quite different from L'_S vs time, being of parabola or hy-perhola type respectively. The variation of the driving force parameter vs time,obtained either calculated or experimental, plotted as a camel hump.
