Second hand vacuum brazing furnace

Today, I’d like to tell you about the advantages and features of the second-hand vacuum brazing furnace. The second-hand vacuum brazing furnace refers to the heating of workpieces in the vacuum chamber, which is mainly used for the welding of high-quality products and easily oxidized materials. The vacuum brazing furnace includes a pressure vessel with a cylindrical side wall and a door, the size and position of which are designed to close one end of the cylindrical side wall. The workpiece processing system is installed on the pressure vessel door to support the metal workpiece for heat treatment or brazing. The workpiece processing system includes a device for rotating the workpiece during the processing. The vacuum system can be connected to the workpiece so that the internal pressure of the workpiece is lower than atmospheric pressure during the brazing process.

1. Vacuum brazing can improve the corrosion resistance of products, avoid all kinds of pollution and pollution-free treatment equipment cost, and have good safety production conditions because of no flux;

2. Vacuum brazing not only saves a lot of expensive metal flux, but also does not need complex flux cleaning process, which reduces the production cost;

3. Vacuum brazing filler metal has good wettability and fluidity, which can weld more complex and narrow channel devices. Vacuum brazing improves the yield of products and achieves a solid and clean working surface;

4. Compared with other methods, the internal structure and fixture of the furnace have long service life, which can reduce the maintenance cost of the furnace;

5. There are many materials suitable for vacuum brazing, such as aluminum, aluminum alloy, copper, copper alloy, stainless steel, alloy steel, low carbon steel, titanium, nickel, Inconel, etc., which can be brazed in vacuum furnace. The designer determines the required materials according to the use of brazing devices, among which aluminum and aluminum alloy are most widely used.

The second-hand vacuum brazing furnace technology is used for locomotive radiator, compressor intercooler, freon and alkene refrigeration system, digging oil cooler, gas turbine regenerator, high-power transformer radiator, as well as the application of household appliances, such as vacuum brazing the core bar of heat exchanger of household air conditioner and various electric heaters. The above is to tell you the advantages and characteristics of the second-hand vacuum brazing furnace, I hope to help you.
