摘要

分析了真空度、温度和氮化物成分对钢中氮溶解度影响

并在50 k真空感应炉对不同化学成分的合金钢(/%:0.06～0.36C、≤3.23Si、≤2.20Al、≤9.00Cr)进行3种氮化物-氮化硅、氮化锰和氮化铬的增氮试验。结果表明

气相中氮气分压对钢液中氮溶解度影响最大;钢中Ti、Cr提高氮溶解度和氮化物的收得率;增加C含量则降低氮溶解度和氮化物的收得率;钢中含有一定量的铝

可以显著提高氮化物的收得率。40 kPa氩气压力

1 600～1 650℃时在硅钢、结构钢和9%Cr钢中氮化硅、氮化锰、氮化铬的收得率分别为25%～30%、30%～50%、60%～100%。

Abstract

The effect of vacuum

temperature and nitride composition on nitrogen solubility in steel is analyzed and the test of adding nitrogen in alloy steel with various chemical composition (/% ： 0. 06 ~0. 36C

≤3. 23Si

≤2. 20Al

≤ 9. 00Cr) by three kinds of nitrides-silicon nitride

manganese nitride and chromium nitride in a 50 kg vacuum induction furnace is carried out. Results show that the effect of nitrogen partial pressure in gas phase on nitrogen solubility in liquid is greatest ； with containing Ti and Cr in steel the nitrogen solubility in steel and yield of nitride increase ； with increasing C content in steel the nitrogen solubility in liquid and yield of nitride decrease ； with containing definite aluminium in steel the yield of nitride obviously increases. With 40 kPa argon pressure at 1 600 ~ 1 650 ℃

the yield of silicon nitride

manganese nitride and chromium nitride being respective in silicon steel

structural steel and 9% Cr steel is respectively 25% ~ 30%

30% ~ 50% and 60% ~ 100%.
