The invention discloses a preparation method of an aluminum alloy profile, and relates to the technical field of preparation methods of aluminum alloys. The method comprises the following steps of preparing an aluminum-silicon ingot by electrolytic in-situ preparation of an aluminum alloy device; putting the prepared aluminum silicon ingot into a die of an extrusion forming machine for extrusion molding to obtain the aluminum alloy base material; cooling and quenching the obtained aluminum alloy profile by adopting a water spraying and soaking method; sequentially spraying a protective layer,a color paint coating and a varnish coating on the quenched aluminum alloy profile by adopting an electrostatic spraying method to prepare the aluminum alloy profile; and cooling to room temperature to finish the preparation of the aluminum alloy profile. The method has the advantages of being energy-saving, high in efficiency, low in cost and the like in the process of preparing the aluminum-silicon ingot.
Description
technical field [0001] The invention relates to the technical field of preparation methods of aluminum alloys, in particular to a preparation method of aluminum alloy profiles. Background technique [0002] Due to its light weight, corrosion resistance and high strength, aluminum alloy is widely used in aviation, aerospace, automobile, shipbuilding and other fields. It is the most important non-ferrous metal alloy in machinery manufacturing, electrical manufacturing, chemical industry and other fields. Another important structural material after steel. Aluminum-silicon alloy is the most important alloy system among aluminum alloys, which can be used in casting, welding, forging and machining. Due to the relatively active chemical properties of aluminum, aluminum is usually prepared by electrolysis of alumina, and the electrolytic aluminum is fused with other elements to prepare an aluminum-silicon alloy. Silicon in the metallurgical industry is usually obtained by reductio...
