以CaO-Al2O3-MgO-BaO为基本渣系用正交设计试验方法得出研制的含CaO(40~50)%,Al2O3(25~35)%,MgO(10~15)%的LF精炼用预熔渣具有1280℃的较低熔点,脱硫效果好。经150t电弧炉150炉统计数据表明,在精炼前钢中硫含量为0.035%~0.072%时,用该预熔渣精炼后,成品钢中硫含量降至0.005%~0.019%(平均硫含量为0.009%),平均脱硫率由原固体合成渣的72%提高到89%,LF平均精炼时间由67min降至53min。 相似文献

16Mn钢V(N)微合金化在大规格高强度角钢生产中的应用 总被引:6,自引:0,他引:6
大规格角钢主要用于铁塔和建筑结构中。唐钢过去用16Mn钢生产Q345级别角钢,因供轧制用钢的内控标准化学成分窄(T16Mn钢%:0.18~0.20C,1.35~1.55Mn,Ceq≥0.41),致使供轧率仅为30%。通过V-N微合金化,开发了T16MnV(N)钢(%:0.14~0.20C,1.30~1.60Mn,0.05~0.09V,0.009~0.018N),V(N)微合金化显著提高了该钢的力学性能:σb520~625MPa,σs395~465MPa,δ5 24%~28%,冲击功43~96J,并取得较高的经济效益。 相似文献
