| description | FIELD: powder metallurgy; steam treatment of the sintered items made out of the iron powders. SUBSTANCE: the invention presents the method of the steam treatment of the sintered items made out of the iron powders and may be used in the powder metallurgy. The method provides for heating of the sintered items up to the temperature of 400-550 C and their oxidation by steam. At that the process of pseudo-fluidization and oxidation is carried out simultaneously with water delivery directly into the working space of the furnace. Technical result is the increase of the items rust resistance and decrease of the production power consumption at the expense of decrease at the steam transportation losses. EFFECT: the invention allows to increase the items rust resistance, to decrease production process power consumption. 1ex |
