    摘要
  • 摘要: 從理論上研究潔凈鋼凝固過程中TiN的析出和形核規律、通過試驗探討潔凈鋼凝固過程TiN形核并作為鐵素體非均質形核核心,以及細化連鑄坯凝固組織消除宏觀偏析的可能性.利用基本凝固理論計算得出了TiN在凝固初期析出的條件,并利用對比試驗方法研究了TiN的實際細化效果.研究表明,通過嚴格的工藝控制,利用TiN形核是一種細化潔凈鋼凝固組織的有效手段.

     

    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.
