| Abstract: | A novel technology for preparation of iron powder from the V-Ti-Fe-concentrate has been investigated in this paper.This technology includes reducing compound agglomeration of V-Ti-Fe-concentrate with carbon powderunder the action of microwave radiation,sifting milled compound agglomeration of V-Ti-Fe-concentrate,reducingiron powder by use of hydrogen.Sdditionally,the influences of feed size,reduction temperature,reduction time,additive of Na_2SO_4 and Fe powder on the iron powder quality were also discussed.And the TFe content in the iron powder reached 98.01% under the optimal conditions. |
