The invention discloses a method for preparing a
vanadium-aluminum
alloy and relates to a method for preparing a
vanadium-aluminum intermediate
alloy for producing a
titanium alloy. The method is characterized by comprising the following steps of: firstly, with aluminum as a
reducing agent, reducing
vanadium pentoxide to prepare a vanadium-aluminum alloy in one step by adopting a metallothermic reduction method; secondly, crushing and
drying the vanadium-aluminum alloy prepared in one step; and adding aluminum in the dried vanadium-aluminum alloy prepared in one step and refining in a second step in a vacuum intermediate-frequency
induction furnace to obtain a final product of the vanadium-aluminum alloy. In the method, by taking the aluminum as the
reducing agent in the metallothermic reduction method (one-
step method) and reserving a small part of aluminum during
smelting of the vanadium-aluminum alloy and adding the aluminum in the refining of the vacuum intermediate-frequency
induction furnace, the problem that the vanadium-aluminum alloy is molten in the vacuum intermediate-frequency
induction furnace can be effectively solved. In addition, compared with the one-
step method for preparing the alloy, the appearance quality, the consistency,
impurity components, the uniformity and other aspects of the alloy are superior and the aim of refining can be achieved. Meanwhile, when being used for refining the vanadium-aluminum alloy, the process can be used for completely molting the alloy at the lower feeding power and has remarkable the energy-saving effect.
