<P>PROBLEM TO BE SOLVED: To improve productivity in a method of a finish heat treatment for iron powder and an apparatus therefor; to improve reaction efficiency of a reactive gas; and to respond to productivity variation. Ž<P>SOLUTION: The apparatus for finish heat treatment of iron powder has a hopper for feeding the iron powder, a heating furnace partitioned into a plurality of zones for heat-treatment of the iron powder and a means for horizontally moving the iron powder. Each zone of the heating furnace has a heating means and an inlet and an outlet for feeding and discharging a treating gas, respectively. The means for horizontally moving the iron powder is a mesh type through which the treating gas can pass. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
