NOVELTY - The technology involves setting primary refining and purification device (1-2) in the primary refining and purification chamber (1-3), and the primary furnace bottom powder spraying refining and purification treatment is performed on the molten aluminum in the intelligent smelting device. A controllable amount of molten aluminum transfer device and a rare earth controllable amount of feeding device (1-5) are arranged between the primary refining purification chamber and the inoculation chamber (1-13). The furnace is air-cooled to room temperature and placed for 4.0 to 6.0 hours, and then installed in a low-temperature furnace for treatment again, and the temperature is set at 160 to 170 °C after the treatment at the lower temperature stage. The holding time is 30 to 45 minutes, and the oven is air-cooled to room temperature for 2.0 to 4.0 hours, and the treatment process is repeated 2-3 times. USE - Intelligent manufacturing technology of graphene and rare earth composite strengthening automobile aluminum wheels used in large passenger car, multifunctionalal sport vehicle and wheel high toughness performance. ADVANTAGE - The graphene, rare earth composite reinforced aluminum alloy material mechanical property satisfy large load automobile aluminium wheel technical quality requirement. The graphene and rare earth reinforced automobile aluminum wheel casting to obtain excellent obdurability, the popularization and application of the technology has promoting effect on the automobile light weight, energy-saving and environment-friendly. The method effectively avoids the graphene easy agglomeration in the melt, and the rare earth easy oxidation segregation problem. The solidification process prevents the growth of the secondary dendritic crystal, and effectively crushing the grown dendrite crystal.
