For aluminum brazing in nitrogen furnace: a flux spraying device sprays flux onto the workpiece, and heats the workpiece to 150 ℃ ~ 250 ℃ for drying through the drying furnace. When the temperature in the brazing furnace with protective atmosphere reaches 610 ℃, the workpiece is brazed. After cooling by water cooling and air cooling, the workpiece is unloaded from the unloading table. The process is as follows:
Welding parts → flux spraying → conveying device → drying furnace → conveying device → heating furnace → brazing furnace → water cooling chamber → air cooling chamber → conveying device.
(1) Flux spraying
A conveyor chain carries the workpiece through a closed flux chamber, in which water containing flux is sprayed on the workpiece. After spraying, the excess flux on the workpiece is removed by an air knife, and then the workpiece is transported to the drying oven.
(2) Drying process
After spraying the flux, the parts need to be dried in the drying oven, and the temperature is usually about 200 ℃. Care should be taken to prevent the heat exchanger from overheating, which may lead to the formation of high-temperature oxides on the aluminum surface.
(3) Continuous brazing furnace
The brazing furnace must ensure that the temperature of the workpiece is increased above 20 ℃ every minute, so that the surface coating solder reaches the melting point (591 ℃). The temperature balance of the workpiece is ± 3 ℃, and the protective atmosphere of nitrogen is maintained in the furnace. The control of workpiece temperature and the consistency of each workpiece temperature are very high, so the heating chamber is divided into several control areas. The more areas, the better the temperature distribution control of the workpiece. Any large fluctuation will lead to insufficient or excessive brazing of the workpiece.
