Embodiment 1

[0015] A production method of aluminum profiles, including melting and casting, extrusion, degreasing, dipping, spraying heat-insulating paint, and coloring treatment processes. The melting and casting includes batching, smelting, and casting. The raw materials used in the batching are: aluminum: magnesium : a mixture of silicon=1:0.4:0.5 in weight ratio, and the raw material aluminum comes from processed recycled aluminum profiles.

[0016] The casting process is as follows: the smelted aluminum liquid is passed through a deep well casting system through a crystallizer to produce aluminum rods, and then cooled to homogenize the ingot.

[0017] The extrusion process is to heat the aluminum rod to 440°C, extrude the heated aluminum rod into various specifications of profiles from the mold with a mold and an extruder, and rapidly air-cool or water-cool during extrusion, and the aging time: Adopt 180 ℃ heat preservation 4 hours.

[0018] The dipping treatment process is: put the...

Abstract

The invention relates to an aluminum profile and provides a production method of an aluminum profile which has uniform and fine surface sand holes, achieves a good heat-insulating effect and produces no light pollution. The production method comprises fusion casting, extruding and coloring and is characterized in that the fusion casting comprises batching, fusion and casting; raw materials used in batching include aluminium, magnesium and silicone which are mixed at the weight ratio of 1:(0.3-0.5):(0.5-0.8); the raw material aluminium is derived from treated and recycled aluminum profiles; deoiling treatment and impregnating treatment are performed before coloring treatment; the impregnating treatment process is that a deoiled aluminum profile workpiece is placed in an impregnating tank, in which ammonium chloride, ammonium bifluoride, sodium fluoride, potassium permanganate and water are added at the weight ratio of (5-8):(10-14):(25-28):(12-15):balancing amount.

Description

technical field [0001] The invention relates to an aluminum profile, in particular to a production method of the aluminum profile. Background technique [0002] The method of producing aluminum profiles in the prior art is as follows: 1. Melting and casting, calculate the addition amount of various alloy components according to the specific alloy grade to be produced, and reasonably match various raw materials; add the prepared raw materials into the melting furnace according to the process requirements The slag and gas in the melt are effectively removed by means of degassing and slag removal and refining; the smelted molten aluminum is cooled and cast into various specifications through the deep well casting system under certain casting process conditions. Round cast rod. 2. Extrusion molding, first design and manufacture the mold according to the section of the profile product, and use the extruder to extrude the heated round cast rod from the mold. 3. The surface of co...
