Aluminothermic reduction method of vanadium-iron alloy

Abstract

The invention discloses an aluminothermic reduction method of a vanadium-iron alloy. The aluminothermic reduction method comprises the following steps: S1, weighing and mixing a vanadium oxide, a reducing agent, a slag former and an iron material; s2, after uniform mixing, the first part of the mixture, the second part of the mixture and the third part of the mixture are sequentially added into a smelting furnace; and S3, after the materials are added, electrode arc striking is adopted, electrifying smelting is started, electrifying is continuously conducted after a good molten pool is formed, a furnace body is cooled at the normal temperature after the reaction is completed, the furnace is disassembled after the surface of slag metal is skull, obtained alloy cakes are subjected to water quenching, finishing and crushing, and finally the ferrovanadium alloy product meeting the component and particle size requirements is obtained. According to the method, the modes of non-uniform burdening, layered material distribution and electric auxiliary heating smelting are adopted, the burning loss of an initial reaction reducing agent is reduced, the reduction efficiency of the reaction process is improved, and rapid separation of reaction products is promoted, so that the smelting yield of the ferrovanadium alloy is greatly improved, and the product quality is effectively controlled.
