Abstract The blast furnace-blast oxygen furnace (BF-BOF) steel production process is a typical iron and steel process,and also is typical iron-coal chemical process with high energy consumption and large carbon emissions,which is in a key area for Chinese iron and steel industry to achieve the goal of carbon neutrality. In 2020,the production of steel produced by this process accounted for over 90% of the national crude steel production,and the BF-BOF steel process is an important source of CO2 emissions in the iron and steel industry. Therefore,the carbon emission calculation and carbon neutralization path research of companies based on the typical BF-BOF steel process has attracted attention. At present,there are a variety of calculation methods for carbon emissions of iron and steel companies at home and abroad,but different CO2 calculation boundaries and methods have great differences in the results of companies′ CO2 emissions,and the influencing factors are also different. The carbon emission characteristics of the steel production process are introduced. Taking a typical production process as an example,it analyzes the carbon emission,carbon emission accounting methods,and influencing factors of the whole steel process from the perspective of system boundary,and calculates the carbon emissions of 3.9 million tons and 5.5 million tons of iron and steel companies under different methods,and compares the differences between different calculation methods. The results show that the proportion of CO2 emissions in the pre-iron process of company A and company B to the total carbon emissions is 60.99% and 54.12%,respectively. Coking,sintering and ironmaking processes should be given priority to reduce CO2 emissions in the iron- and steelmaking process. The factors affecting the emission reduction in the iron- and steelmaking process mainly include the consumption of fossil fuels,the recovery rate of energy,the proportion of self-generated electricity and the selection of carbon emission factors. Among them,the consumption of fossil fuels accounts for more than 80% of the total CO2 emissions,which is the largest source of CO2 emissions from the iron- and steelmaking process. Meanwhile,the application effects and carbon emission reduction paths of different technologies and measures are analyzed with the goal of carbon neutrality of the whole steel process,which is to provide a theoretical basis for iron and steel companies to achieve the carbon peak-carbon neutrality goal and a useful reference for companies to formulate a carbon neutrality roadmap.
