Example Embodiment
[0029] Example 1
[0030] a) Heat the forged piece after forging to 900℃ and keep it for 30 minutes;
[0031] b) The forgings processed in step a are continuously and forcedly cooled under the air blower to cool the temperature of the forgings to 550°C and the cooling time is 150s;
[0032] c) Cooling the forging processed in step b to 200°C at room temperature;
[0033] d) Put the forgings processed in step d into the material frame for stacking and cooling.
Example Embodiment
