With the development of high grade steels,it becomes more and more difficult for BOF to pro-duce low sulfur steel.At present main factors causing resulfurization during semi steel smelting process in Pangang Group Xichang Iron&Steel Company are incomplete skimming desulfurization slag,contribution of auxiliary materials and unsuitable smelting slag composition.After optimizing,desulfurization slag skim-ming procedure,controlling feeding materials quality,improving smelting process and slag washing desul-furization during tapping,average resulfurization reduces from 0.003% down to 0.001%.
