<p>PURPOSE: A method for manufacturing super-high strength aluminum using scrap is provided to reduce raw material cost by recycling scraps of all series of aluminum as raw material, and improve mechanical properties by simultaneously selectively adding metal constituents and performing rapid cooling treatment process. CONSTITUTION: The method for manufacturing super-high strength aluminum using scrap comprises the processes of forming rectangular shaped fiber by drip-feeding a solution prepared by melting scrap in a melting furnace from a nozzle(12-2) and scattering the scrap molten solution using centrifugal force of a rotation cone(13) rotating in a rotation speed of about 100 to 500 revolutions per minute; and manufacturing aluminum fiber by first age-hardening the formed rectangular shaped fiber in a low temperature chamber(16), wherein the method further comprises a separation process of gravitationally storing non-fiberized scrap in the manufactured aluminum into a scrap storage container(22-1) and moving fiber to a fiber hardening part(23) by heating air sent from a fan(19) to a temperature of about 80 to 100 deg.C using a burner(20) and supplying the heated air into the low temperature chamber(16); a cooling process of constantly maintaining temperature of the fiber hardening part(23) by installing a cooling water chamber around the fiber hardening part(23); and a storage process of storing a second age-hardening completed fiber prepared by quenching operation for about 2 to 5 hours required for natural hardening into a fiber storage container(25-1), wherein a pressure reduction barrel(26) and a filter(27) are installed in the storage container(25-1) to prevent the fiber from being discharged into the outside.</p> |
