Fact Sage was used to calculate the precipitation temperature of Al2O3 based on the composition of the IF steel shown in Table 1，and it was found that when[Al]and[O]contents were very low in the liquid steel，the Al2O3 inclusions began to precipitate，and the precipitation temperature was above 1950 K（Fig.8），which is far higher than steelmaking temperature.In the RH process，the oxygen activity in molten steel was generally more than 300×10-6before deoxygenation.When Al was added into steel as a deoxidizer，many Al2O3 inclusions were formed in the liquid steel，which is different from the precipitation of TiN in the solidification process.In summary，the cooling rate had little effect on the precipitation of Al2O3 inclusions，and the size of the inclusions was strongly influenced by the particle collision and polymerization.This is consistent with the results of irregular changes in the number and size of Al2O3 inclusions.
