Estimation of sulphur in synthetic slags for the studies of sulphur partition between pig iron and slags using radioactive tracer

Using radioactive tracer technique, estimation of sulphur content in synthetic slags for the studies of partition of sulphur between master alloy of pig iron containing 1.064% of sulphur and synthetic slags has been carried out. The investigations carried out at 1550°C when slag samples were withdrawn at predetermined intervals, show that the percentage of sulphur in slags increases with the increase of the time interval but after a certain period, the sulphur content tends to be constant. The experiments conducted with equal amounts of master alloy and synthetic slag in one case and by decreasing the amount of slag to half in the other case, indicate that the sulphur content in the slag samples in the latter case is high.
