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.
With the development of high grade steels,it becomes more and more difficult for BOF to produce 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 skimming procedure,controlling feeding materials quality,improving smelting process and slag washing desulfurization during tapping,average resulfurization reduces from 0.003％ down to 0.001％.
