Abstract:The hot metal with 0.06%-0.12% of w([S]) was used for steelmaking at Pangang Extraction Vanadium and Steelmaking Plant. It’s difficult to product low sulfur steel. According with the practicing of the low sulfur steel of X52NS and L245NCS etc in Pangang, the sulfur content controlling technology was analyzed for the whole flow process including hot metal desulphurization pretreatment, converter ladle refining and continuous casting. Through controlling sulphur under 0.003% after the hot metal desulphurization pretreatment and using sulfur lower accessories slag in converter smelting station and molten steel LF station control [O] activity etc, Pangang Extraction Vanadium and Steelmaking Plant can produce the mass fraction of sulfur for 0.002% low sulfur steel.
