Summary: | The invention discloses a preparation process of aluminum alloy profiles for ships, and relates to the technical field of material machining. The preparation process mainly comprises the steps of burdening, smelting, casting, uniform heat treatment, machining treatment, ingot heating, mold heating, extrusion cylinder heating, extrusion production and stretching; and through optimization of aluminum alloy melt components, the specific extrusion production process and stretching process are developed to improve the strength and the corrosion resistance of the aluminum alloy profiles for the ships. In the preparation process, based on a traditional preparation process, the aluminum alloy melt components are optimized to lay foundation for subsequent processes; the specific extrusion production process and stretching process are developed; the parameters of the extrusion production process are optimized; and the stretching force in the stretching process is strictly limited, so that the hardening in machining is |
