[Technical Field Applied] The present invention relates to a method for producing an aluminum-vanadium master alloy used in producing a titanium alloy, and mainly relates to the thermite method. [Prior art and problems] Conventionally, vanadium pentoxide (V 2 O 5 ) or sodium hexavanadate (Na 2 V 6 O 16 ) has been used as the vanadium raw material used in this type of method, for example, as disclosed in Japanese Patent Publication No. 53 -7368, JP 60-36632
No. 60-50129 and US Pat. No. 3,190,750. As shown in these prior art techniques, the reaction in the method using V 2 O 5 as a vanadium raw material can be expressed as follows: 3V 2 O 2 + 10Al→6V + 5Al 2 O 3 ...(1) For example, in order to generate 1 kg of metal, 0.88Kg of aluminum (Al) for reduction is required, and the amount of aluminum oxide (Al 2 O 3 ) produced is also
Since the amount was as large as 1.67Kg and the slag melting point rose too much, the amount of slag-forming agent used to suppress the rise in melting point also tended to increase. [Purpose] This invention reduces the amount of aluminum used as a reducing agent and also reduces the amount of aluminum oxide produced, thereby lowering the slag melting point,
The purpose is to reduce the amount of slag-forming agent used that lowers the slag melting point, increase the production amount relative to the volume of the reaction vessel, and reduce production costs. [Means for Solving the Problems] The present invention provides a method for producing an aluminum-vanadium mother alloy for producing titanium alloys by an aluminothermite method, in which vanadium trioxide (V 2 O 3 ), vanadium tetroxide ( The problem was solved by providing a method for producing an aluminum-vanadium master alloy used in the production of titanium alloys, which is characterized by using at least one type of V 2 O 4 ). [Embodiment] As mentioned above, as the vanadium raw material of this invention, whether V 2 O 3 or V 2 O 4 is used alone or a mixture thereof, the invention is the same. . That is, if vanadium as a raw material is represented by a general formula, it can be represented by V 2 O x (where x=3 to 4). As the reducing and alloying Al, known powdered aluminum is used, and as the slag forming agent, calcium oxide (CaO) and other materials similar to known ones are used. Therefore, if the reduction reaction carried out by the known Thermite method is expressed by the reaction formula, it will be as follows: 3V 2 O 4 +8Al→6V+4Al 2 O 3 ...(2) or 3V 2 O 3 +6Al→6V+3Al 2 O 4 ...(3) [Effect] As mentioned above, in the method of this invention, as is clear from the comparison of formulas (2) and (3) with formula (1) of the conventional example, theoretically When V 2 O 4 is used as the vanadium raw material, the amount of reducing agent Al used can be approximately 20% smaller than when using conventional V 2 O 5 , and similarly, V 2 O 3 When using V 2 O 3 and V 2 O 4 as the vanadium raw material, the amount of reducing Al can be reduced by about 40%, and when a mixture of V 2 O 3 and V 2 O 4 is used as the vanadium raw material, V 2 O 5 can be reduced depending on the mixing ratio. The amount of reducing Al used is about 20% to 40% less than when it was used (see Table 1).

Next, when actually manufacturing Al-V master alloy, the composition is 50-50wt% Al-V (Experimental Example 1) and 15-50wt% Al-V.
The raw material supply amount, theoretical values, and experimental values of reaction results are shown in Table 2 assuming 85 wt% (Experimental Example 2). However, the slag melting point was set at the same temperature (1600°C).

A more specific explanation of the thermite method used in the above embodiments is as follows. Example 1 As an example, the amount shown in Experimental Examples 1 and 2 was exactly 10 times as much as raw material V 2 O x (x = 3 to 4), Al powder for reduction and alloying, slag of CaO, etc. The mixture was mixed uniformly and then placed in a refractory-lined steel reaction vessel, ignited, and reacted. After the reaction was completed, each mixture was allowed to cool and solidify. After cooling, it was taken out from the reaction vessel, unclean parts were removed, and the product was crushed to adjust the particle size. The slag melting point during the reaction was 1600°C, and the recovered Al-V alloys were about 10 times the amount of Experimental Examples 1 and 2, respectively. Example 2 As in Example 1, the molten alloy after the reaction was taken out from the bottom of the reaction vessel and poured into a mold, and before the hot water solidified in the mold, argon gas (Ar) was blown from the bottom of the mold. The alloy was solidified in a mold, and after cooling, the alloy was taken out from the mold, the unclean portion was removed, and then crushed, and the particle size was adjusted to obtain a finished product. The obtained products were approximately 10% each of Experimental Examples 1 and 2.
It was double the amount. Note that Cl 2 may be used instead of argon gas (Ar),
Increases the cleanliness of the alloy.
