摘要
The present invention provides a method for preparing ferrovanadium alloys based on aluminothermic self-propagating gradient reduction and slag washing refining. The method includes the steps of (1) performing aluminothermic self-propagating gradient reduction; (2) performing heat preserving and smelting to obtain an upper layer alumina-based slag and a lower layer alloy me (3) jetting refining slags into the lower layer alloy melt, and performing stirring and slag washing refining; and (4) cooling the refined high-temperature melt to room temperature, and removing an upper layer smelting slag to obtain the ferrovanadium alloys.
