Abstract

This invention provides a method for manufacturing aluminum profiles from aluminum scrap that does not generate fumes through high-temperature melting, reduces carbon emissions and manufacturing processes, is environmentally friendly and energy-saving, and also allows for labor savings and cost reductions. [Solution] The method for manufacturing aluminum profiles from aluminum scrap according to the present invention includes the following steps: A step of recovering aluminum scrap, screening and removing impurities to obtain pure aluminum scrap. A step of placing the aluminum scrap in an extruder and extruding it at 250 kg / cm³. 2 The process involves compressing aluminum scrap into a cylindrical aluminum billet by applying the above pressure. The aluminum billet is then placed in a heating furnace at a temperature of 460°C to 510°C to heat and soften, further improving its plasticity and reducing its deformation resistance. After heating, the aluminum billet is placed in an extrusion machine to extrude aluminum profiles, which are then formed into shapes such as rods, tubes, sheets, or wires.

Description

Technical Field

[0001] The present invention relates to a method for manufacturing aluminum profiles from aluminum scraps.

Background Art

[0002] Conventionally, in the process of recycling general aluminum scraps, after collecting the aluminum scraps, it is necessary to melt them at high temperature and then make recycled aluminum materials by die casting or casting. However, in this process, a large amount of toxic fumes are generated by melting at high temperature, and it also increases carbon emissions and manufacturing processes, which is not only harmful to the environment but also consumes energy, prolongs the working hours and increases the cost. And in the context of the global circular economy and the attention to energy conservation and carbon reduction, replacing natural aluminum materials with recycled aluminum materials is a positive effort for the aluminum industry to achieve the zero-carbon goal.

Summary of the Invention

Problems to be Solved by the Invention

[0003] The main object of the present invention is to reduce the fumes generated by high-temperature melting, reduce carbon emissions and manufacturing processes, be environmentally friendly and energy-saving, and also save working hours and reduce costs in the process of compacting aluminum scraps, heating them and extruding aluminum profiles.

Means for Solving the Problems

[0004] The method for manufacturing aluminum profiles from aluminum scraps according to the present invention includes the following steps. A step of collecting aluminum scraps, screening and removing impurities to obtain pure aluminum scraps. A step of placing the aluminum scraps in an extruder, and the extruder presses at a pressure of 250 kg / cm or more to compact the aluminum scraps into cylindrical aluminum billets.​This process involves placing an aluminum billet in a heating furnace at a temperature of 460°C to 510°C to heat and soften it, further improving the plasticity of the aluminum billet and reducing its deformation resistance. This process involves placing the heated aluminum billet into an extrusion machine to extrude the aluminum profile, which is then formed into shapes such as rods, tubes, sheets, or wires. [Effects of the Invention]

[0005] The advantage of the method for manufacturing aluminum profiles from aluminum scrap according to the present invention is that, in the process of compressing and heating the aluminum scrap to extrude the aluminum profiles, no fumes are generated due to high-temperature melting, reducing carbon emissions and the manufacturing process. This is not only environmentally friendly and energy-saving, but also enables reductions in labor and costs. [Brief explanation of the drawing]

[0006] [Figure 1] This is a flowchart of the method for manufacturing aluminum profiles from aluminum scrap according to the present invention. [Modes for carrying out the invention]

[0007] The technical means used to achieve the above-described purposes and effects of the present invention will be described below with reference to the drawings, with reference to preferred implementable embodiments.

[0008] The method for producing aluminum profiles from aluminum scrap according to the present invention includes the following steps, as shown in Figure 1: 1. A step of recovering clean, impurity-free aluminum scrap, screening and removing impurities to obtain pure aluminum scrap. 2. Placing the aluminum scrap in an extruder and extruding it at 250 kg / cm³. 2The process involves compressing aluminum scrap into a cylindrical aluminum billet by applying the above pressure. The aluminum billet is then placed in a heating furnace at a temperature of 460°C to 510°C and heated to a higher temperature, which softens the aluminum billet and further improves its plasticity, reducing its deformation resistance. After heating, the aluminum billet is placed in an extrusion machine to extrude the aluminum profile, which can take the form of a rod, tube, sheet, or wire. This process reduces the fumes generated by high-temperature melting during the process of compressing and shaping the aluminum scrap, followed by heating and extruding the aluminum profile. Furthermore, it reduces carbon emissions and manufacturing processes, making it environmentally friendly and energy-saving, as well as saving labor and costs.

[0009] As described above, the present invention certainly achieves the desired purpose and effect, and is more ideal and practical than conventional inventions. However, the embodiments described above are merely for illustrative purposes of preferred embodiments of the present invention and do not limit the scope of the present invention. Any equivalent modifications and alterations made under other technical means disclosed herein are all included within the scope of the present invention.
