Embodiment 1
[0012] In the first stage, the newly cast grid is put into the curing room, and CO is introduced into the curing room 2 , so that the CO in the curing chamber 2 The volume concentration reaches 13%, and then steam is introduced to heat and humidify, so that the temperature in the curing room reaches 70°C and the humidity reaches 98%, and lasts for 24 hours.
[0013] In the second stage, the grid is transferred to the drying room. The temperature in the drying room is 85°C, stored for 4 hours, cooled naturally, and stored in a ventilated environment at room temperature for 10 hours before coating.
Embodiment 2
[0015] In the first stage, the newly cast grid is put into the curing room, and CO is introduced into the curing room 2 , so that the CO in the curing chamber 2 The volume concentration reaches 15%, and then steam is introduced to heat and humidify, so that the temperature in the curing room reaches 65°C and the humidity reaches 99%, and lasts for 12 hours.
[0016] In the second stage, the grid is transferred to the drying room. The temperature in the drying room is 80°C, stored for 6 hours, cooled naturally, and stored in a ventilated environment at room temperature for 12 hours before coating.
Embodiment 3
[0018] In the first stage, the newly cast grid is put into the curing room, and CO is introduced into the curing room 2 , so that the CO in the curing chamber 2 The volume concentration reaches 18%, and then the steam is heated and humidified, so that the temperature in the curing room reaches 60°C and the humidity reaches 99%, and lasts for 48 hours.
[0019] In the second stage, the grid is transferred to the drying room. The temperature in the drying room is 90°C, stored for 2 hours, cooled naturally, and stored in a ventilated environment at room temperature for 15 hours for coating.
