Abstract：Steel cleanliness is increased under customer’s requirement.Steel producers are striving to produce cleaner steels.Therefore, to reduce the quantity and size of nonmetallic inclusions in the steel is imperative, especially for high quality coldrolled products. The main controlling is oxygen activity in the molten steel and FeO+MnO in the slag at the blowing endpoint of BOF steelmaking,because they are the main source of producing nonmetal inclusions.Based on our study work and recent literature,oxygen content control of low carbon at the blowing endpoint of BOF and influence of the oxygen content at the blowing end on decarburization in the RH vessel are discussed.According to the results,decreasing measurements of endpoint oxygen content are put forward.
