Abstract :
In this paper, the effect of MgO, BaO, Na2O and SrO addition to a pre-melted CaO-Al2O3-Si2O synthetic
slag on sulfur removal from plain carbon steel was studied under the same experimental conditions. The slags were
pre-melted at 1400°C in an electric resistant furnace and desulfurization experiments were carried out in a high
frequency induction furnace. The results showed that the optimum reaction time for desulfurization was 15 min. It was
found that while SrO addition to the ternary slag enhances the sulfur removal capability, MgO, Na2O and BaO
additions reduce desulfurization efficiency of the ternary slag. Moreover, it was observed that restricting access to
oxygen from the atmosphere by using a covered crucible, could increase desulfurization efficiency of the slag by more
than two fold.
