Embodiment 1
[0051] A magnesium alloy forging cake forging process is based on the diameter D = 300mm, the composition is (wt.%): Al8.2 ~ 8.5; Mn0.2 ~ 0.25; Zn0.4 ~ 0.5; Cu≦0.05; Ni≦0.005 ; Si≦0.15; Be≦0.02; Fe≦0.05; other impurities≦0.3; the balance is Mg, the homogenized magnesium alloy continuous casting ingot is forged into a magnesium alloy forging cake with a diameter of 695mm and a thickness of 105mm; including the following step:
[0052] a. Material flaw detection: Remove surface scale and visible cracks from the continuous casting billet, process it into an ingot with a height of 550mm and a diameter of 300mm, and use ultrasonic waves to detect flaws in the billet to ensure that there are no obvious cracks and shrinkage cavities inside the billet , inclusion defects;
[0053] b. Heating: Heat the ingot without obvious cracks, shrinkage cavities and inclusion defects to 400°C, keep it warm for 6 hours, and heat the hydraulic press mold to 300°C;
[0054] c. Thickness of pier: St...

[0063] c. Thickness of pier: put th...
Embodiment 3
[0069] A magnesium alloy forging cake forging process is based on the diameter D = 350mm, the composition is (wt.%): Al8.2 ~ 8.5; Mn0.2 ~ 0.25; Zn0.4 ~ 0.5; Cu≦0.05; Ni≦0.005 ; Si≦0.15; Be≦0.02; Fe≦0.05; other impurities≦0.3; the balance is Mg and the homogenized continuous casting ingot is forged into a magnesium alloy forging cake with a diameter of 700mm; including the following steps:
[0070] a. Material flaw detection: Remove surface scale and visible cracks from the continuous casting slab, process it into a billet with a height of 525mm and a diameter of 350mm, and use ultrasonic waves to detect flaws in the billet to ensure that there are no obvious cracks, shrinkage cavities, etc. inside the billet. inclusion defects;
[0071]b. Heating: Heat the ingot without obvious cracks, shrinkage cavities and inclusion defects to 430°C, keep it warm for 10h, and heat the hydraulic press mold to 350°C;
[0072] c. Thickness of the pier: Stand the ingot after heating and heat pr...
