Embodiment Construction
[0037] The present invention will be further described below in conjunction with accompanying drawing:
[0038] Such as Figure 1 to Figure 4 Shown: the present invention is by weight percentage: 0.42%~0.44%Si, 0.50%~0.55%Mg, 0.005%~0.03%Ti, 0~0.18%Fe, 0~0.025%Zn and the chemical composition composition of surplus Al .
[0039] The production method of above-mentioned large-diameter 6063 aluminum alloy round ingot is as following technological process:
[0040] A. Melt smelting process
[0041] Add cold material and part of the Al-Si intermediate alloy into the melting furnace, use the siphon to introduce the electrolytic aluminum liquid into the melting furnace, add modifiers, ingredients, and complete the melting process through electromagnetic stirring.
[0042] B. Melt refining process
[0043] After smelting, the melt goes through furnace bottom blowing, powder spraying refining, slag removal, and standing still, and then transfers to a static furnace, where bottom blow...
