    • To understand inclusions in tire cord steel, the solidification process has been analyzed and the conclusions drawn as follows. Al2O3 precipitates earlier during solidification and the growth rate depends on the diffusion of [A1] in molten steel; SiO2 begins to precipitate when the solidification fraction is 0.44, and the growth rate depends on the diffusion of [O]. The inclusion radius increases with the decrease of cooling rate, the radii of Al2O3 and Al2O3-SiO2 inclusions are 2.5 μm and 4.7 μm, respectively, after solidification as the cooling rate is 100 K·min-1. SiO2 content increases and Al2O3 content decreases during solidification.
