Vanadium alloy and preparation method and device thereof

The invention relates to the technical field of vanadium alloy preparation, and specifically relates to a vanadium alloy and a preparation method and device thereof. The preparation method of the vanadium alloy comprises the following steps that vanadium slag, a slag former and a reducing agent are uniformly mixed and then smelted, and then separating is conducted to obtain a crude alloy; the crude alloy, a vanadium oxide, the reducing agent and the slag former are mixed and then subjected to refining, and then separating is conducted to obtain the vanadium alloy; the smelting temperature ranges from 1450 DEG C to 1650 DEG C; and the refining temperature ranges from 1450 DEG C to 1700 DEG C. The smelting and refining combined smelting process is adopted, smelting is conducted firstly, coarse reduction of the vanadium slag is achieved, then refining is conducted, vanadium in the vanadium slag can be fully recycled by regulating and controlling the temperature in the smelting and refining process, and the vanad
