Abstract:The process characteristics and development status of modern blast furnace ironmaking and non-blast furnace ironmaking (direct reduction, smelting reduction) are analyzed, and the advantages and disadvantages of each process under existing production conditions are compared from many aspects. From the energy structure, production scale and process maturity, it is expounded that blast furnace ironmaking is still the main process in China. Combined with the current trend of low carbon development at home and abroad and the policy requirements, the measures to reduce carbon consumption of blast furnace process are put forward. At the same time, the development direction of "short process" instead of "long process" and new energy instead of carbon metallurgy was clarified, so as to realize "zero carbon ironmaking" finally. The development direction of hydrogen metallurgy is pointed out according to the current international energy structure adjustment direction.
