| 摘 要： | 采用25 t EAF-VOD+LF-680 kg铸锭工艺冶炼0. 14%C-0.35%N 的奥氏体不锈钢1Mn15Cr17Ni2N。VOD精炼后，N]为0.040%,0]为0.0158%;通过LF吹氮45 min,吹氮量50 m³,分析得出N]为0.139%, O]为0.0033%,吹入氮气平均回收率为33.07%。再加人500 kg氮化铬(8.60%N)和150 kg氮化锰(5.13%N),取样分析N]为0.35%, O]为0.0029%,加氮化铬和氮化锰的氮综合回收率为87.41%。

| Abstract: | 0.14C-0.35N austenite stainless steel 1Mn15Cr17Ni2N melted by 25 t EAF - VOD LF - 680 kg ingot process. N] was 0.040% and O] was 0.0158% at end of VOD refining, and the analysis results indicated N] 0.139% and O] 0.0033% after nitrogen blown for 45 min in LF with blown nitrogen amount 50 m3with blown nitrogen average yield 33.07%. Then added 500 kg chromium nitride (8.60%N) and 150 kg manganese nitride (5.13%N), with sampled analysis the N] was 0.35% and the O] was 0.0029%, the comprehensive yield for added chromium nitride and manganese nitride was 87.41%. |
