摘　　要：对超低硫工业纯铁的精炼深脱硫工艺进行了研究,通过开展LF炉、RH炉脱硫试验,对比不同条件下的脱硫效果,并从热力学、动力学方面对试验结果进行剖析。研究发现,工业纯铁经过LF炉精炼造渣脱硫,炉渣中不稳定氧化物(FeO+MnO)含量低、炉渣碱度高、流动性好,脱硫效果显著。采用LF炉精炼脱硫工艺,可以使工业纯铁成品硫的质量分数达到0.0010%以内的水平。The refining and deep desulfurization process of ultra-low sulphur industrial pure iron was studied in this paper.The desulfurization experiments were conducted in LF and RH furnaces,comparing the desulfurization effects under different conditions and analyzing the experimental results from thermodynamic and kinetic aspects.It was found that industrial pure iron undergoes LF furnace refining to form slag for desulfurization,resulting in low content of unstable oxides(FeO+MnO)in the slag,high alkalinity of the slag,good fluidity,and significant desulfurization effect.By using the LF furnace refining and desulfurization process,the sulfur content of industrial pure iron products can reach a level within 0.0010%.
