Abstract:
     By means of the technology and equipment, the high-temperature gas which is produced from a reducing-smelting shaft-furnace and has a temperature higher than 1000 deg.C is used to pre-reduce the mineral powder is a cyclonic pre-reductive apparatus, and the pre-deoxidised mineral powder is reduced, in solid state under 950 deg.C medium-temperature and high-temperature smelting state (1800-2000 deg.C) in the cyclonic deoxidising shaft furnace. In this invention, the raw material is mineral powder and the fuel is coal powder. The economical benifit obtained is notable.
