摘要: 随着西昌钢钒高级别钢种的不断开发,转炉控制硫含量越来越困难。为了满足低硫品种钢的要求,调查得出半钢冶炼过程回硫主要因素为脱硫渣未扒净、炼钢辅料带入及冶炼过程炉渣成分不合适。通过优化脱硫扒渣工艺、控制转炉入炉原材料、优化转炉冶炼工艺及出钢过程渣洗脱硫,转炉平均回硫由原来的0.003%降低至0.001%,回硫控制效果明显。

Abstract: 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%.
