Embodiment 1

[0018] S1: Weighing each raw material for melting and casting to obtain an ingot;

[0019] S2: Extrusion: After the ingot obtained in S1 is homogenized, the car skin is removed, and extrusion is carried out on a hydraulic press. Before extrusion, the extrusion cylinder, extrusion die and ingot are heated. After extrusion, the profile is Cool down to below 50°C, stretch and straighten the profile, and then heat treatment. The heating method of the extrusion barrel is: raise the temperature to 90°C and keep it for 0.6h, then raise the temperature to 195°C and keep it for 0.7h, then raise the temperature to 300°C and hold it for 0.6h. After heat preservation for 0.9h, heat up to 385°C and hold heat for 0.6h, then heat up to 475°C, place the extrusion die in a holding furnace at 490°C for 7 hours for heating, and place the ingot in a holding furnace for 1 hour at 460°C for heating , wherein, the deformation amount of stretch straightening is 3%, and the extrusion rate is 35m / min; ...

[0022] S1: Weighing each raw material for melting and casting to obtain an ingot;

[0023] S2: Extrusion: After the ingot obtained in S1 is homogenized, the car skin is removed, and extrusion is carried out on a hydraulic press. Before extrusion, the extrusion cylinder, extrusion die and ingot are heated. After extrusion, the profile is Cool down to below 50°C, stretch and straighten the profile, and then heat treatment. The heating method of the extrusion barrel is: raise the temperature to 120°C and hold it for 0.8h, then raise the temperature to 210°C and hold it for 0.6h, then raise the temperature to 310°C and hold it for 0.8h. After 1 hour of heat preservation, the temperature was raised to 390°C and held for 0.8 hours, then the temperature was raised to 470°C, the extrusion die was placed in a holding furnace at 480°C for 7 hours for heating, and the ingot was placed in a holding furnace for 2 hours at 510°C for heating. Among them, the deformation amount of stretching ...

Abstract

The invention discloses an anodic alumina alloy section bar, and relates to the field of metal materials. The anodic alumina alloy section bar comprises0.75-0.90wt% of Mg, 0.5-0.6wt% of Si, 0.10-0.14wt% of Cu, 0.20-0.25wt% of Mn, 0-0.1wt% of Ti, 0-0.1wt% of Cr, 0.1-0.3wt% of Fe, 0.20-0.28wt% of Zn, and the balance of Al. Alloy components in the above aluminum alloy section bar material are optimized, and melting casting, homogenization, extrusion, heat treatment and surface layer treatment in the production process are optimized, so the mechanical performances and the surface layer film quality of the section bar are effectively improved.

Description

technical field [0001] The invention relates to the field of metal materials, in particular to an anodized aluminum alloy profile. Background technique [0002] The advantages of sliding windows are simplicity, beauty, large window width, large glass block, wide field of vision, high lighting rate, convenient glass cleaning, flexible use, safety and reliability, long service life, open in one plane, occupy less space, and install screen windows conveniently Wait. At present, sliding windows are the most widely used in doors and windows. Compared with other metal profiles, aluminum alloy profiles have the advantages of light weight, beautiful appearance and economy. At present, sliding windows are mainly made of aluminum alloy profiles. In the prior art, the performance of the anodized aluminum alloy profiles has not yet reached the optimum level, and continuous improvement is still needed. [0003] Therefore, how to obtain an excellent aluminum alloy profile by optimizing ...
