Requirements for aging framing operations of industrial aluminum profiles
1. When hoisting materials into the furnace, the ends of the aluminum profiles and the air guide pipes should be within 80 to 100mm.
2. Insulated curtain wall aluminum profiles and insulated window profiles must be aged in the same aging furnace. The temperature in the furnace is controlled within the range of 180℃±3℃. After reaching the temperature, it is kept for 3 hours and released. After being released, the fan is turned on for 20 minutes. After cooling, the quality inspector checks the hardness;
3. Insulating profiles and ordinary profiles are not allowed to be mixed in the confrontation frame.
4. Insulated curtain wall aluminum profiles and insulated window profiles must be installed in the confrontation frame respectively.
5. For small materials with wall thickness ≥2mm, 80mm ventilation channels must be left at both ends of each frame.
6. If the aging insulation profile does not meet the needs of the furnace, you can put 1 to 2 frames of ordinary profiles (wall thickness below 2.0mm) in the same furnace for aging. The aging effect is basically tested according to the performance of the insulation profile.
7. Ordinary curtain wall profiles, ordinary door and window profiles, and industrial profiles must be aged in the same aging furnace. The temperature in the furnace is controlled within the range of 195°C ± 5°C. After reaching the temperature, it is kept warm for 3 hours and released. Industrial aluminum profiles are released from the oven and the fan is turned on immediately. Blow for 20 minutes to cool down, and the quality inspector will test the hardness.
8. Flat mold materials with wall thickness ≥4mm are not allowed to be stacked (only 1 piece is allowed per layer).
9. When the temperature in the furnace reaches the required temperature, the aging worker will use a glass tube thermometer to measure the actual temperature in the furnace every 30 minutes and make original records.
10. Ordinary curtain wall aluminum profiles, ordinary door and window profiles, and building profiles must be installed in the counterweight frame respectively.
