Production process of solar support frame aluminum alloy profile

[0027] Such as figure 1 As shown, a production process of aluminum alloy profiles for solar bracket frames, the production steps are as follows:

[0028] S1. Select raw materials; the percentages of each element in the raw materials are: Si, 0.38%~0.42%, Mg, 0.53%~0.57%, Fe not more than 0.18%, and the remaining elements are Al;

[0029] S2. Smelting: melting the raw materials in step S1 at a melting temperature of 720°C to 760°C;

[0030] S3. Casting; casting is carried out by semi-continuous direct water-cooling casting method, the casting temperature is 710°C~730°C, the casting speed is 50~70mm / min, and the cooling water pressure is 0.1~0.3MPa; The speed block refines the casting structure and increases the density of the structure, thereby improving the mechanical properties and heat treatment effect.

[0031] S4, homogenize the cast rod structure;

[0032] S5, extruding the cast rod processed in step S4 to obtain an aluminum profile;

[0033] S6, adopt straightening ma
