    ABSTRACT:
    China, a country with a total industrial energy consumption ranking in the forefront of the world. China's steel industry has a large energy consumption and low energy recycling rate, which is one of the reasons for the limited development of Green & Low-Carbon metallurgy. BOF gas, with an annual output of more than 100 billion standard cubic meters, is one of the main by-product energy resources in the steelmaking process. However, the up to 34.7% abandoned rate of BOF gas has caused a lot of carbon emissions and energy resources waste. The abandoned BOF gas, with a high temperature of 1773~1873K and 20~40%(vol.%) CO and 20~30%(vol.%) CO<sub>2</sub>, has a huge physical sensible heat and chemical latent heat. It means there is a predictable recyclable value and comprehensive utilization prospects to achieve the ultra-low carbon emissions, reduction of energy consumption, resources recovery and energy conversion in iron and steel making process. The paper has carried out detailed calculation and analysis of the energy value of abandoned BOF gas, and the feasibility analysis and program design of the overall resource recycling and energy utilization in iron and steel making process that include blast furnace (BF) smelting of vanadia-titania magnetite (VTM), Combined blowing in BOF and vanadium-extracting converter, Co-production of steel-chemicals industry.
