The invention provides a high-strength aluminum profile hot
extrusion forming method, and relates to the technical field of aluminum profile
machining. The hot
extrusion forming method for the high-strength aluminum profile comprises the steps that a blank is prepared, a proper aluminum
alloy material is selected, inclusions in the
raw material are removed, the
raw material is
cut into the required length and shape, heating
smelting treatment is conducted, and the temperature suitable for
extrusion is achieved while it is guaranteed that components are uniform. By optimizing the
smelting process and adopting advanced
smelting technologies such as
electromagnetic stirring and vacuum smelting, the component uniformity of molten aluminum is ensured, parameters such as smelting temperature, time and stirring speed are strictly controlled,
alloy elements are fully dissolved and uniformly distributed,
raw material inspection is enhanced, and raw materials are strictly inspected and screened, so that the production cost is reduced, and the production efficiency is improved. The aluminum ingots containing the inclusions are removed, and before smelting, the aluminum ingots can be pretreated, such as cleaning and preheating, so that the introduction of the inclusions is reduced.
