METHOD FOR MANUFACTURING EXTRUDED ALUMINUM ALLOY CAPABLE OF OMITTING A HOMOGENIZING HEAT TREATMENT PROCESS OF AN ALUMINUM ALLOY BILLET

摘要

PURPOSE: A method for manufacturing extruded aluminum alloy is provided to homogenize an aluminum alloy billet by preheating the aluminum alloy billet at high temperature.;CONSTITUTION: A method for manufacturing extruded aluminum alloy is as follows; a step for generating an aluminum alloy billet by injecting molten steel in a mold(S10); a step for cutting the aluminum alloy billet at a constant size(S20); a step for homogenizing micro segregation(S30); a step for chamfering the surface of the aluminum alloy billet(S40); and a step for extruding the aluminum alloy billet to a desired shape(S50).;COPYRIGHT KIPO 2013;[Reference numerals] (S10) Casting step; (S20) Cutting step; (S30) Heating step; (S40) Chamfering step; (S50) Extruding step
