| Abstract: | The current researches and development trends of oxygen blast furnace process were summarized and discussed from the perspectives of mathematical model, laboratory experiment and industrial trial. Moreover, the profile design was discussed in this paper. The results show that proper direct reduction degree and thermal reserve temperature should be determined or used in the static simulation of blast furnace process. Meanwhile, compared with conventional blast furnace, the change of productivity, the change of heat loss, the limit of coal injection and the problem of N2 accumulation due to top gas recycling etc. should be all considered. It concluded the problems existing in the multi-dimensional kinetic models and multi-objective optimization models of oxygen blast furnace. Nevertheless, are pointed out future mathematical simulation trend of these two kinds of models. The profile designs including furnace height, bosh angle and shaft angle, and tuyeres were analyzed based on the characteristics of oxygen blast furnace process described in literatures. |
