The invention belongs to the field of metallurgy and particularly relates to a method for smelting FeV80 through an electro-aluminothermic process. To achieve the technical purpose of providing the method for smelting FeV80 through the electro-aluminothermic process, ferrovanadium fine powder is uniformly laid at the bottom of a straight cylindrical furnace and added in smelting raw materials containing V2O5, so that the effect that a molten ferrovanadium alloy layer is formed at the furnace bottom in the smelting process is achieved, and a knotted layer at the furnace bottom is prevented from making direct contact with a smelting slag layer; and meanwhile, the ferrovanadium fine powder is added into the smelting raw materials containing V2O5 to absorb the extra heat, and the purposes of reducing the content of MgO in the ferrovanadium smelting slag and improving the slag system characteristics are achieved.
