摘要
The present invention relates to a method for manufacturing a sintered ferromolybdenum alloy, in which a mixed powder of a mill scale (a mixture of Fe, FeO and Fe2O3) as a ferrous raw material discharged from a hot rolling and forging process of the steel-making process and a molybdenum oxide powder as a molybdenum raw material is primarily reduced with a hydrogen gas at low temperature, and then is secondarily reduced with the hydrogen gas at high temperature and simultaneously is cooled in a hydrogen atmosphere to thereby obtain a ferromolybdenum alloy in the form of a powder, and subsequently the obtained ferromolybdenum alloy powder is mixed with wax (Kenolube P11) and the wax-containing mixture is compacted or pressure-molded, after which the molded product is heat-treated in a hydrogen gas atmosphere and then is cooled, thereby manufacturing a sintered ferromolybdenum alloy, and a sintered product manufactured by said method.
