Production method of low-iron vanadium-aluminum alloy and vanadium-aluminum alloy

The production method of the low-iron vanadium-aluminum alloy comprises the following steps of grinding, burdening, mixing, bottoming, charging, vacuumizing in a reaction kettle, stopping a vacuum pump and filling argon into a furnace body when the vacuum degree reaches-0.09 +/-0.01 MPa and the argon filling pressure reaches-0.07-0.08 MPa, carrying out ignition reaction, igniting, cooling, discharging from the furnace, carrying out slag removal and finishing on a vanadium-aluminum alloy ingot, and carrying out high-temperature treatment on the vanadium-aluminum alloy ingot to obtain the low-iron vanadium-aluminum alloy. According to the high-quality vanadium-aluminum alloy for smelting the high-purity metal vanadium, the components in the vanadium-aluminum return slag are controlled, and the content is obtained through calculation and detection, so that the problem of high content in a product caused by repeated use of the return slag and iron enrichment is avoided. 本发明提出的低铁钒铝合金的生产方法及钒铝合金，包括以下步骤：研磨、配料、混料、铺底、装
