Abstract：The effect of aluminumnitride in low carbon aluminumkilled steels produced by TSCR was studied. The results show that the precipitation of aluminumnitride had no distinct effect on the grain size and mechanical properties of aluminumkilled low carbon steel plates produced by TSCR of which acidsoluble aluminum content was 0005%0.043%, so it was suggested that the precipitation of aluminumnitride was not the main factor of grain refining. Only a small quantity of aluminumnitride could be precipitated and had faint effect of precipitation strengthening, so the aluminumnitride was not the dominating factor of steel strengthening too. But the precipitation of aluminumnitride had obvious effect on the grain coarsening in steel plates during reheating, and the grain coarsening temperature was increased with the increment of acidsoluble aluminum content，or aluminumnitride content.
