| 摘 要： | 从理论上研究洁净钢凝固过程中TiN的析出和形核规律,通过试验探讨洁净钢凝固过程TiN形核并作为铁素体非均质形核核心,以及细化连铸坯凝固组织消除宏观偏析的可能性.利用基本凝固理论计算得出了TiN在凝固初期析出的条件,并利用对比试验方法研究了TiN的实际细化效果.研究表明,通过严格的工艺控制,利用TiN形核是一种细化洁净钢凝固组织的有效手段.

| Abstract: | Precipitation and nucleation of TiN during solidification of clean steel have been studied. And the possibility of using TIN to refine as-cast grains as heterogeneous nucleation sites as well as to reduce mac-rosegregation in continuous casting of steel is discussed. The conditions that TiN precipitates at the beginning of solidification have been acquired and the effectiveness of this TiN refining as-cast structure process has been investigated with comparative experimental methods. It is shown that refining grains by inoculating clean steel with TiN is an effective way provided that the process is controlled strictly. |
