Abstract: 0. 14C-0.35N austenite stainless steel 1Mn15Cr17Ni2N melted by 25t 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 [0]0.0033% after nitrogen blown for 45 min in LF with blown nitrogen amount 50 m³ with 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%.

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%。
