Abstract：According to the basic principle that sulfur in molten steel spreads to slag at a deoxidizing atmosphere, by improving slag making technics, process temperature control, argon blowing optimization, deoxidizing ambience control in refining process, accurate control of refining wire feeding, and other strengthening measures, through the improvement of slag performance, the desulfurizing efficiency of ladle furnace is improved, refining period is shortened, production efficiency is also improved, and the production cost is reduced, which can lay a good foundation for the development and production of highpurity low sulfur steel in the future.
