| 摘 要： | 通过X100管线钢(%:0.03～0.05C、1.70～1.90Mn、0.15～0.25Si、≤0.001S、≤0.002P)凝固过程脱氧热力学研究,确定了在凝固过程中的固液两相区析出Ti2O3夹杂的最佳钢液组成。研究表明,为使X100管线钢在凝固前沿的固液两相区中析出细小的Ti2O3夹杂颗粒,关键在于控制钢液中钛含量≤0.01%,铝含量≤0.002%,氧含量≤0.001%,氮含量≤0.004%。

| Abstract: | The optimum conditions of molten steel to precipitate Ti2O3 inclusion in solid-liquid dual phase region during solidification are obtained by study on thermodynamics of deoxidization of pipeline steel X100 (0. 03 ~0. 05C, 1.70 ~ 1. 90Mn, 0. 15 ~0. 25Si, ≤0. 001S, ≤0. 002P) during solidification. The results showed that control of titanium content in molten steel ≤0. 01% , aluminum content ≤0. 002% , oxygen content ≤0. 001% and nitrogen content ≤0. 004% were key factors to promote precipitation of fine Ti2O3 particles at front of solidification in solid-liquid dual phase region of pipeline steel X100. |
