DETAILED DESCRIPTION - Manufacture of graphene and rare earth composite reinforced aluminum-silicon-copper-magnesium material involves (i) melting aluminum (A00) ingot, (ii) heating the melted aluminum liquid to 660-680℃ for heat preservation, (iii) using bell jar to press the high-purity silicon with a particle size of less than 5.0 mm and high purity magnesium with bulk volume of less than 125-512 cm3into the aluminum liquid, and stirring for 3.0-5.0 minutes, (iv) gradually overheating the aluminum liquid to 760-780℃ for 20-30 minutes, (v) adding aluminum-copper alloy (Al10Cu) and aluminum-titanium (Al10Ti) intermediate alloy into the aluminum liquid, and heating for 20-30 minutes to form aluminum-silicon-copper-magnesium alloy liquid, (vi) adding aluminum-cerium (Al5Ce) intermediate alloy into the alloy liquid for alloying treatment, (vii) keeping the temperature of alloy liquid at 750-760℃, and adding a rod-shaped aluminum-strontium (Al10Sr) intermediate alloy and a small-block-shaped aluminum-titanium carbide (AlTiC) alloy, and (viii) adding aluminum titanium graphene intermediate alloy for modification treatment and crystal grain refinement treatment. The device used for preparation of aluminum-titanium graphene intermediate alloy and aluminum rare earth intermediate alloy contains aluminum-titanium particle and graphene homogenizing preparation device (A), an aluminum particle and rare earth particle homogenizing preparation device (B), a mold and a heating furnace. The device (A) is used for forming smoke of aluminum-titanium particles and graphene powder in a closed box body using nitrogen as a carrier through a blowing device to carry out homogenizing mixing. The graphene blowing device releases charges in the atomization process, and graphene powder with charges is effectively adsorbed on aluminum-titanium particles of the smoke atomization, and the aluminum particles and rare earth particles are added into the rolling cylinder, and are subjected to homogenization treatment under the protection of inert gas, and mixed particles are injected into the section mold which is a steel casting mold, compacted and placed in a heating furnace for heating and heat preservation. The heating furnace is provided with a cooling blowpipe for blowing and cooling the alloy liquid which is smelted in the mold after being discharged.
