Vacuum brazing furnace model

The vacuum brazing furnace produced by the vacuum furnace manufacturer is a large-scale heat treatment equipment, which can perform various processes such as vacuum annealing, vacuum brazing, and vacuum aging. Can be programmed into a number of different programs, can control and program hundreds of heat treatment curve points, divided into up, down, left and right and front and back six areas for temperature control, multi-point and single-point temperature recorder and over-temperature protection device The uniformity of the furnace temperature can be controlled within a constant temperature range, in addition to the high-purity nitrogen high-flow heavy-duty device.

At present, vacuum brazing furnaces produced by vacuum furnace manufacturers are mainly used for vacuum aluminum brazing of air conditioner evaporators, radar network antennas, aluminum plate-fin heat exchangers, waveguides and automobile heat exchangers, and can also be used for vacuum brazing. High temperature brazing of materials such as cemented carbide, stainless steel, titanium alloys and high temperature alloys.

Vacuum brazing furnaces can be divided into two types depending on the application: one is a VBF series vacuum brazing furnace, and the other is a VHB series high temperature vacuum brazing furnace.

Vacuum brazing furnaces produced by vacuum furnace manufacturers have the following characteristics:

1. The vacuum brazing furnace asks for notes when heating. Therefore, it does not affect the physical and chemical properties of the base metal or has a relatively small effect. Vacuum brazing furnaces can successfully weld some complex parts, such as multiple welds of a heat exchanger.

2. The deformation of the workpiece treated by the vacuum brazing furnace is relatively small, and it is relatively easy to ensure the size of the assembly. Since it is heated in a vacuum state, it is advantageous for removing the oxide film and the grease on the surface of the workpiece, and therefore, the surface brightness of the workpiece is relatively high. In addition, since the vacuum brazing furnace does not require a flux, it is not necessary to perform a cleaning process after welding.
