The invention discloses a method and device for preparing an aluminum-vanadium master alloy by a two-step method. In step 100, vanadium pentoxide and the first aluminum are placed in an aluminothermic reaction furnace, and the second aluminum is placed in a vacuum refining furnace; Step 200, connect the aluminothermic reaction furnace and the vacuum refining furnace through a connecting pipe, then close both ends of the connecting pipe, and then vacuumize the vacuum refining furnace; Step 300, put the vanadium pentoxide and the The first aluminum is subjected to aluminothermic reaction to obtain a molten aluminothermic reaction product; step 400, the molten aluminothermic reaction product is cooled, formed and crushed to obtain the primary aluminum vanadium master alloy, and then The primary aluminum vanadium master alloy is added to the vacuum refining furnace; step 500, melting the primary aluminum vanadium master alloy and the second aluminum in the vacuum refining furnace. The method avoids inter-equipment transfer of each process by making the whole process can be carried out coherently.
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...
