Heat-resistant aluminum alloy processing technology

[0019] A heat-resistant aluminum alloy processing technology, the method comprises the following steps:

[0020] Step 1. Weigh 24 parts of Mg, 4.2 parts of Mn, 3.2 parts of Fe, 1.6 parts of Cr, 3 parts of Zr, and 48 parts of Al as melting materials, put the melting materials into a vacuum induction furnace for smelting, preheat at 400°C for 4 hours, The temperature of the alloy liquid is controlled at 750°C during melting, and electromagnetic stirring is performed every 30 minutes;

[0021] Step 2, adding refining agent hexachloroethane to the alloy liquid in the above steps, the addition amount is 1.5% of the total weight of the alloy, and the time interval of electromagnetic stirring is 10min;

[0022] Step 3, import the alloy liquid refined in the above steps into the filter box through the ceramic foam filter plate, and set it at 700°C;

[0023] Step 4, the alloy liquid in the filter box of the above step is cast through water-cooled semi-continuous casting, and the alloy li

[0032] Weigh 20 parts of Mg, 2.1 parts of Mn, 3.2 parts of Fe, 1.6 parts of Cr, 3 parts of Zr, and 48 parts of Al as smelting materials, put the smelting materials into a vacuum induction furnace for smelting, preheat at 400°C for 4 hours, and the alloy The liquid temperature was controlled at 750° C., and electromagnetic stirring was performed every 30 minutes; the rest of the steps were the same as in Example 1.

[0034] Weigh 19 parts of Mg, 1.2 parts of Mn, 3.2 parts of Fe, 1.0 parts of Cr, 3 parts of Zr, and 48 parts of Al as melting materials, put the melting materials into a vacuum induction furnace for smelting, preheat at 400°C for 4 hours, and the alloy The liquid temperature was controlled at 750° C., and electromagnetic stirring was performed every 30 minutes; the rest of the steps were the same as in Example 1.
