Abstract

Abstract: Precipitation condition and nucleation of Ti2 03 during solidification of clean steel have been studied. The behavior of Ti2 03 during solidification as well as possibility of using Ti203 to refine as-cast grains as heterogeneous nucleation sites is discussed. It is shown that Ti2 03 can be formed provided that the steelmaking and solidification process is controlled strictly. And inoculating clean steel with Ti203 is an effective way to refine as-cast grains.

Key words: clean steel, solidification, Ti2O3,
