[0023] Example 1
[0024] The preparation method of the electrolytic aluminum steel claw aluminum ash protective ring includes the following steps:
[0025] A. Cool the aluminum ash raw materials salvaged during the casting of molten aluminum to room temperature, then grind them with a ball mill, and select materials with a particle size ≤ 2mm for use;
[0026] B. Dry the selected materials through a kneader for 5-10 minutes, then add 8% of the total weight of the raw materials, and then wet-mix for 15-20 minutes through the kneader, and finally put them into the molding machine for vibration molding. Aluminum dust protection ring; the adhesive is a paper dust adhesive formed after corrugated paper is immersed in water and crushed;
[0027] C. Put the raw aluminum ash protection ring into the roasting furnace, and roast it to 300±10℃ according to the baking process, heat it for 30 minutes, and then cool to room temperature to obtain the finished aluminum ash protection ring;
