The first imported off-gas analysis system on 150 t BOF at Benxi Plates Co. Ltd. is presented and the continuous determination of bath carbon content has been studied. The comparison between the whole-course carbon integral model and the end-point carbon prediction model has been made. The results show that the regular change of CO, CO2 and N2 content in the off-gas during blowing plays an important role in judging the smelting end-point of converter; the cubic curve fitting model has a higher hit rate over 95% for the heats whose end-point carbon content is lower than 0.10% with a precision of ±0.02% and has a large error for the heats whose end-point carbon content is more than 0.15%.
