Taking the smelting process in blast furnace as the research object, according to the carbon flow chart of blast furnace, carbon dioxide emission model of blast furnace was established, and operation rules of carbon flow for the smelting process in blast furnace were analyzed. The appropriate carbon dioxide emission factor and the calculation formula were formulated, charged coke accounted for 46.27 percent of the total blast furnace carbon input and the blast furnace gas used for power consumption accounted for 48.39 percent of the total carbon input, the carbon emission using for smelting iron accounted for 57.26 percent of the total blast furnace carbon output and the blast furnace gas entering the pipe network accounted for 34.23 percent of the total carbon output. Based on the analysis results, some measures to reduce carbon dioxide emission were put forward, such as reducing carbon-containing energy consumption in the blast furnace smelting process, optimizing the smelting process in blast furnace and using advanced energy-saving technologies, and so on.
