Embodiment 1
[0022] Taking the H13 mold as an example to illustrate the treatment process of the aluminum alloy extrusion porous mold.
[0023] (1) Annealing: Spheroidizing annealing is adopted, that is, the mold is put into a heating furnace at 850°C for 4 hours, and then slowly cooled with the furnace at a rate of 35°C / h, and the mold is cooled to 500°C when it is released for air cooling.
[0024] (2) Quenching: After annealing, the mold is preheated in two stages firstly at 400°C for 5 minutes, then at 820°C for 5 minutes, then rapidly heated to 1000°C for 10 minutes, and quenched with 50°C warm water Cooling method, during the quenching heating and heat preservation process, anti-oxidation and decarburization coating is applied around the mold.
[0025] (3) Tempering: Put the quenched mold into a heating furnace and keep it warm at 500°C for 4 hours, and repeat the tempering twice.
[0026] (4) Cleaning: soak the tempered mold in acid solution for 10 minutes, take out the mold and ri...
Embodiment 2
[0031] (1) Annealing: Spheroidizing annealing is adopted, that is, the mold is placed in a heating furnace at 860°C for 3.5 hours, and then slowly cooled with the furnace at a rate of 36°C / h, and the mold is cooled to 520°C when it is released for air cooling.
[0032] (2) Quenching: The mold after annealing is preheated in two stages firstly at 420°C for 5 minutes, then at 820-850°C for 5 minutes, then rapidly raised to 1020°C for 5-10 minutes, then quenched Adopt 52°C warm water cooling method, and use anti-oxidation and decarburization paint to coat around the mold during quenching heating and heat preservation.
[0033] (3) Tempering: Put the quenched mold into a heating furnace and keep it warm at 520°C for 3.5 hours, and repeat tempering 3 times.
[0034] (4) Cleaning: soak the tempered mold with acid solution for 12 minutes, take out the mold and rinse it with clean water, then polish it with water sandpaper, brush the rust, and rinse it clean, and finally put it in met...
Embodiment 3
[0039] (1) Annealing: Spheroidizing annealing is adopted, that is, the mold is put into a heating furnace at 880°C for 2.5 hours, and then slowly cooled with the furnace at a rate of 38°C / h. When the mold is cooled to 530°C, it is air-cooled.
[0040] (2) Quenching: After annealing, the mold is preheated in two stages firstly at 430°C for 5 minutes, then at 830°C for 5 minutes, then rapidly raised to 1050°C for 8 minutes, and quenched with warm water at 58°C Cooling method, during the quenching heating and heat preservation process, anti-oxidation and decarburization coating is applied around the mold.
[0041] (3) Tempering: Put the quenched mold into a heating furnace and keep it warm at 580°C for 3 hours, and repeat tempering 3 times.
[0042] (4) Cleaning: soak the tempered mold in acid solution for 13 minutes, take out the mold and rinse it with clean water, then polish it with water sandpaper, scrub the rust, and rinse it clean, and finally put it in metal purification l...
