Abstract

Recently CO2 emission reduction has become an imminent problem, iron and steel industry, as the third largest CO2 emitter industry, is vital for energy conservation and emission reduction in China. Accurately quantifying CO2 emissions is the basis for energy-saving and emission reduction of the iron and steel industry. According to the definition of carbon footprint recommended by IPCC, with a typical BF-BOF route mill as a case, we established carbon footprint model and developed a calculation method of CO2 emissions. Based on the actual data , we calculated the CO2 emission of the total and each process, used 1t plain carbon steel as a functional unit. The results show that the total CO2 emission of the case mill is 2084.37kg /t-cs, of which, the largest CO2 emission process is iron-making process that accounts for about 79??.... Followed by the sintering process, which accounts for 12.7??...of total. Thus, the energy-saving and emission reduction of iron-making process and sintering process is necessary to study how to reduce the carbon footprint per ton of steel for iron and steel mill in China.
