Abstract:Noncoking ironmaking is one of innovative technologies for the development of steel industry. Till now, direct reduction has been one indispensable part of the world steel production. Smelting reduction has also realized the industrialization, which owes the advantages of lower environment load, lower energy consumption and lower production cost (the first item has been practically proved,and the latter two items are still under validation). Development of DRI production is feasible to compensate the shortage of scrap, which is very critical to the rational growth of steel industry and equipment manufacture in China. For China, the main development direction of direct reduction is to adopt the process of coal gasificationshaft furnace reduction on basis of domestic technologies and iron ore resources and that of smelting reduction is to closely follow the evolution of overseas processes, to further strengthen the research and development of domestic technologies, to fully absorb the COREX process and realize the localization of COREX equipments.
