Abstract:By analyzing the end-point data of a 300t-BOF in a domestic steelmaking company, it is founded that the factors of converter life, end-point temperature, oxygen consumption and so on have impacts on BOF end-point. A critical carbon content exists in the BOF blowing process. Below the critical carbon content, the decarburizing reaction gets harder and molten steel is greatly peroxided. The critical carbon content of 0.02%-0.03% is calculated corresponding to the ferrous oxide activity with regular solution model. The optimum end-point carbon content of 300t BOF is 0.03%-0.05% through the theory analysis and practice statistics.
