The industrial experiments on deep desulphurization by using (CaO+Al2O3) complex based fluxes instead of conventional CaO-CaF2 fluxes were carried out through flux addition in RH process.The results show that the average De-S rate of 53.44% has been achieved and the sulphur content in molten steel after RH refining is cut down to less than 24×10-6.The influence of modification treatment of the ladle top slag and final slag composition at the end of RH treatment on De-S is analyzed.The optimum composition of De-S agent is determined to be CaO+BaO (60%~65%) -Al2O3 (20%~25%) -MgO (5%~7%) -CaF2 (<5%).
