Research on Melting of Molybdenum-Bearing Hot Metal by Injecting Molybdenum Oxide Powder

The theoretic calculations were performed on reduction thermodynamic of molybdenum oxide powder based on different chemical composition and temperature of hot metal. The scale-up experiments were carried out at 80 t hot metal ladle and results indicate that yield of molybdenum will reaches over 98% by adopting such technical parameters as the size distribution of molybdenum oxide powder being 0. 10 ~0. 15 mm, injection time being 30 ~35 min, injection rate being3. 0 ~3. 5 kg/min.
