Manufacturing method of molybdenum or vanadium oxide briquetting for steelmaking alloying

The invention discloses a manufacturing method of molybdenum or vanadium oxide briquetting for steelmaking alloying, which comprises the following steps of: adding an inhibitor, a fluxing agent and a reducing agent into molybdenum or vanadium oxide; uniformly mixing the raw materials; wetting the mixture by a water-soluble adhesive; and pressing the wet mixture into a block, wherein the inhibitoris magnesia, the fluxing agent is fluorite and the reducing agent is ferrosilicon powder or carborundum powder. In the oxide briquetting, MgO contained in the magnesia is in tightly contact with MoO3or V2O5 to generate magnesium molybdate or vanadium molybdate difficult to volatilize by the solid-phase reaction, and the volatilization of MoO3 or V2O5 can be effectively inhibited; and meanwhile, the magnesia is difficult to hydrate and a water soluble compound (water glass, brine, urea-formaldehyde resin or the like) can be used as the adhesive. The method is simple and easy to operate, has high yield of directly alloying elements and can be popularized and applied in steel and iron works. Not only can the energy be greatly saved, the CO2 emission is reduced and the environmental load is reduced, but also the alloying cost of molten steel can be greatly reduced.
