在0.5和8～10t的钢水包中进行喷吹(Na_2CO_3+O_2)的试验,结果表明:铁水中原始[si]>0.2%时,向铁水中喷吹Na_2CO_3,硅首先被氧化,然后进行脱硫、脱磷和脱钒反应;向铁水中喷吹(Na_2CO_3+O_2)时,由于铁水和渣中的氧化位提高,促进了脱磷、脱钒反应的进行。采用这种喷吹工艺,可取得脱硫率和脱磷率≥90%,脱钒率≥85%,钠化钒渣的转浸率≥95%的优良冶金效果。 The results show that when the original [si]> 0.2% of molten iron is injected into the molten iron, Na_2CO_3 is sprayed into the molten iron, and the silicon is oxidized first and then desulfurized , Dephosphorization and de-vanadium reaction. When blowing (Na_2CO_3 + O_2) into the molten iron, the dephosphorization and de-vanadium reaction are promoted due to the increase of oxidation sites in the molten iron and slag. Adopting this injection process, the excellent metallurgical effect of desulfurization rate and dephosphorization rate of ≥90%, vanadium removal rate of ≥85% and sodium tripodal vanadium residue conversion rate of ≥95% can be obtained.
