Embodiment 1

[0016] Melting and casting process: set the mass percentage Si to 0.44%, Fe to 0.15%, Cu to 0.02%, Mn to 0.03%, Mg to 0.55%, Zn to 0.02%, Ti to 0.03%, Cr to 0.03%, and a single impurity to 0.01 %, the total impurity is 0.1%, and the rest is Al raw materials put into the smelting furnace for smelting. During the smelting process, the temperature is controlled at 710°C. In step c, the temperature of the molten aluminum is controlled at 710°C for refining and slag removal. Water and nitrogen blow the slag agent into the molten aluminum through the refining tank to separate the aluminum slag and loosen the slag to facilitate cleaning. At this time, the temperature is controlled at 730°C. In step e, the post-furnace test is qualified Finally, the molten aluminum in the furnace was left to stand for 20 minutes, and the temperature of the molten aluminum was controlled at 730°C to pour water and cast aluminum rods. pores, air bubbles. In the filtering step, the filtering method is f...

[0021] Melting and casting process: the mass percentage Si is 0.48%, Fe is 0.14%, Cu is 0.015%, Mn is 0.026%, Mg is 0.56%, Zn is 0.016%, Ti is 0.027%, Cr is 0.023%, and a single impurity is 0.008% , the total impurity is 0.08%, and the rest is Al raw materials put into the smelting furnace for smelting. During the smelting process, the temperature is controlled at 720°C. Blow the slagging agent into the molten aluminum through refining cans to separate the aluminum slag and loosen the slag to facilitate cleaning. At this time, the temperature is controlled at 720°C. In step e, after the post-furnace test is qualified, Put the molten aluminum in the furnace to stand for 25 minutes, control the temperature of the molten aluminum at 736°C and pour water to cast aluminum rods. The function of standing still is to release the air and nitrogen brought in during refining and slag removal, so as to avoid pores during melting and casting. bubble. In the filtering step, the filtering m...

[0026] Melting and casting process: the mass percentage Si is 0.46%, Fe is 0.12%, Cu is 0.018%, Mn is 0.02%, Mg is 0.58%, Zn is 0.018%, Ti is 0.024%, Cr is 0.026%, and a single impurity is 0.007% , with a total impurity of 0.07%, and the rest of the raw materials being Al are put into the smelting furnace for smelting. During the smelting process, the temperature is controlled at 730°C. Blow the slagging agent into the molten aluminum through refining cans to separate the aluminum slag and loosen the slag to facilitate cleaning. At this time, the temperature is controlled at 720°C. In step e, after the post-furnace test is qualified, Put the molten aluminum in the furnace to stand for 25 minutes, control the temperature of the molten aluminum at 740°C and pour water to cast aluminum rods. The function of standing still is to release the air and nitrogen brought in during refining and slag removal, so as to avoid pores during melting and casting. bubble. In the filtering step,...

Abstract

The invention belongs to the field of 6 series aluminum alloy materials, and particularly relates to a manufacturing method of 6036 aluminum alloy sections. According to the existing 6036 manufacturing technology, waste products are likely to be produced, and therefore the manufacturing cost is improved. In order to solve the problem, the manufacturing method of the 6036 aluminum alloy sections comprises a casting process, an extrusion process and an aging process. In the casting process, ingredients are controlled within a certain range, and impurities are reduced. In the gas hole extrusion process, air cooling adopts the water cooling process, and adverse factors of deformation and difficult size control caused by water cooling to production are reduced, and the production efficiency and the first-pass yield are greatly improved. By means of the manufacturing method, 6036 aluminum alloy sections achieve the mechanical performance of 6063-T6, the strength of extension is larger than or equal to 250 MPa, the yield strength is larger than or equal to 220 MPa, and the percentage elongation after fracture is larger than or equal to 10%.
