The invention discloses a preparation method of an electrolytic aluminum steel jaw aluminum ash protection ring. The preparation method comprises the following steps: firstly, aluminum ash raw materials salvaged in casting of molten aluminum are cooled to reach a normal temperature, and are crushed by a ball mill; then, the selected materials are dryly mixed by a kneading machine, are added with a corrugated paper ash binding agent being 8-12% of the total weight of the raw materials, are wetly mixed by the kneading machine, and are put in a forming machine for vibration formation; and finally, a raw aluminum ash protection ring is roasted to 300+-10 DEG C, is heated by 30 minutes, and is cooled to the room temperature to obtain a finished aluminum ash protection ring. The waste aluminum ash is directly adopted as the raw materials, and is matched with the binding agent produced by corrugated papers to preferably solve the aluminum ash bonding problem to achieve the effect of changing wastes into wealth; and the preparation method can largely increase the recycling rate of the waste aluminum ash, largely reduces the enterprise production cost, is free of influence on an electrolyte system, prolongs the life of a steel jaw by 3 times, and also can reduce the aluminum oxide consumption by about 5 kg/tAL.
