The invention discloses a method and device for preparing an aluminum-vanadium intermediate alloy through a two-step method. The method comprises the steps that 100, vanadium pentoxide and first aluminum are placed in an aluminothermic reaction furnace, and second aluminum is placed in a vacuum refining furnace; 200, the aluminothermic reaction furnace communicates with the vacuum refining furnace through a communicating pipe, then the two ends of the communicating pipe are sealed, and then the vacuum refining furnace is vacuumized; 300, the vanadium pentoxide and the first aluminum are subjected to an aluminothermic reaction, and a molten aluminothermic reaction product is obtained; 400, the molten aluminothermic reaction product is cooled, formed and crushed to obtain a primary aluminum-vanadium intermediate alloy, and then the primary aluminum-vanadium intermediate alloy is added into the vacuum refining furnace; and 500, the primary aluminum-vanadium intermediate alloy and the second aluminum in the vacuum refining furnace are smelted. According to the method, the whole process can be carried out coherently, and transfer among equipment of each process is avoided.
Description
technical field [0001] The invention relates to the technical field of master alloys, in particular to a method and a device for preparing an aluminum-vanadium master alloy by a two-step method. Background technique [0002] The master alloy is based on a metal, and one or several simple substances are added to it to solve the problems of easy burning of the simple substance, high melting point, high density and easy segregation, or special alloys to improve the properties of the alloy. It is an additive functional material. Generally, aluminum-vanadium master alloys are prepared in an open environment, resulting in the preparation of aluminum-vanadium master alloys mixed with too many impurities, such as nitrogen and oxygen. [0003] In the prior art, the above-mentioned problems are generally solved by the method of secondary vacuum smelting, such as the patent document whose publication number is CN110331321A, which mainly completes the first preparation by first carryin...
