Beschreibung
Zusammenfassung:	Disclosed is a sintered ore production process in which some or all of the iron ore powder which includes the crystallized water of Pisolite or Marra Mamba minerals etc. used as the sintering raw material is subjected to preliminary reduction in a reducing furnace, as a fluidized layer for example, using reducing gas such as blast furnace gas, and the crystallized water in the iron ore powder is removed and at the same time the hematite in the powdered iron ore is reduced to magnetite or wustite. Then a raw material wherein other iron ore powder, miscellaneous sources of iron, auxiliary raw materials, returned ore and setting material have been compounded with the pre-reduced iron ore is used in the sintered ore powder production process.
