| description | The invention discloses a quadruple smelting process of a high-temperature alloy, and the quadruple smelting process of vacuum induction (VIM), electroslag remelting (ESR), first vacuum consumable remelting (VAR) and second remelting (VAR) is adopted for smelting to prepare the high-purity high-temperature alloy. According to the method, gas and inclusions in the consumable ingot are effectively reduced through the first vacuum consumable remelting, the purity of the consumable ingot is further reduced through the second vacuum consumable remelting, the stability of the consumable smelting process is further improved, voltage and vacuum degree fluctuation in the second vacuum consumable remelting smelting process is eliminated, and the quality of the consumable ingot is improved. And the edge striking arc phenomenon in the self-consumption process is avoided, the metallurgical defect risk can be effectively reduced, and the harsh quality requirement of the aviation industry can be met.
