Key process for preparing vanadium-nitrogen alloy by mixing ammonium metavanadate and vanadium pentoxide

The invention belongs to the field of metal smelting, and particularly relates to a key process for preparing a vanadium-nitrogen alloy by mixing ammonium metavanadate and vanadium pentoxide, aiming at the problem of high production cost of the existing vanadium-nitrogen alloy, the invention provides the following scheme: the method comprises the following steps: S1, proportioning: adding 100kg of ammonium metavanadate and 280-300kg of graphite carbon powder into every 1000kg of vanadium pentoxide; s2, firing in a furnace: after batching, pressing into a vanadium-nitrogen alloy green pellet material, and then putting the green pellet into a reaction furnace for firing; s3, testing the influence of different addition amounts of ammonium metavanadate on the vanadium-nitrogen content and density of the prepared vanadium-nitrogen alloy, wherein the addition amounts are respectively 50kg, 100kg and 200kg; and S4, comparing the test result of the sintered vanadium-nitrogen alloy. According to the method, the use am
