Brazing Aluminum
Product introduction:
Brazing:
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 processAfter 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.Product quick details: | Mesh belt operating surface height | 900mm | | Normal operating temperature | 600～650℃ | | Furnace temperature uniformity | ±3℃ | | maximum service temperature | 700℃ | | effective working size | 1000mm(Mesh belt width)×250mm(Height of mesh belt) | | The channel size | 1050mm×300mm(Straight edge height) | | Temperature control zone | 6 points in Section 6 of Section 3 (temperature measurement) | | Temperature measuring point layout | The upper and lower of each section + furnace temperature
