Abstract
The invention discloses a production method of a V-Al alloy. The production method comprises the step of igniting vanadium pentoxide, metal aluminum and a coolant as furnace materials and smelting in a reaction device so as to obtain the V-Al alloy and slag, wherein the coolant is a defective product of the V-Al alloy with a grade same as that of the produced V-Al alloy. According to the production method of the V-Al alloy, a novel smelting method is used for smelting the V-Al alloy and successfully producing the V-Al alloy with an extremely low impurity content, wherein the impurity content of the produced V-Al alloy and the impurity content of the V-Al alloy obtained through vacuum smelting by using other methods are on the same level; the V-Al alloy smelting process is innovatively simplified, the impurity content of the V-Al alloy is significantly reduced, the production efficiency of enterprises can be increased, the production cost can be reduced, the alloy quality can be improved, the competitiveness of the enterprises can be enhanced, and the production method of a V-Al alloy has broad market prospects.
Description
technical field [0001] The invention belongs to the technical field of vanadium-aluminum alloy preparation, and more specifically relates to a production method of vanadium-aluminum alloy. Background technique [0002] Vanadium-aluminum alloy is an intermediate alloy that must be added for the preparation of titanium alloy materials for aviation. According to the amount of vanadium contained, it is divided into different grades of vanadium aluminum alloys such as AlV50, AlV55, AlV65, AlV75, AlV80, and AlV85. [0003] The Chinese patent document with the publication number CN102154569A discloses a method for preparing vanadium-aluminum alloy, which directly smelts vanadium-aluminum alloy by using vanadium pentoxide and metallic aluminum as charge materials without adding a coolant. Because the thermal reaction of vanadium pentoxide and aluminium releases a large amount of heat, the reaction in the furnace will be splashed if no coolant is added, which will reduce the yield o...
