Frequently Asked Questions
What vacuum levels can the brazing furnace achieve?
The furnace operates under a working vacuum range of 10-1 to 10-6 mbar (optional). Heating under these vacuum levels (10-2~10-6 mbar) effectively removes adsorbed gases and surface impurities, preventing weld porosity and inclusion defects.
What is the maximum operating temperature and uniformity?
The furnace can reach a maximum temperature of 1320℃, with a normal operating temperature range between 540℃ and 1280℃. It features multi-zone independent temperature control combined with a PID algorithm to maintain a temperature uniformity of ±5℃.
How does the cooling system work, and what pressure does it support?
It utilizes inert gases (Nitrogen or Argon) combined with a high-speed, large-flow fan for rapid, controlled cooling. The gas cooling pressure ranges from 0.87 to 2.8 barabs, with optional support for up to 10 barabs.
Can this furnace join complex structures and different materials?
Yes. It supports the overall brazing of complex structures like multi-layer laminated sheets, honeycombs, and small runners (e.g., heat exchanger fins, rocket nozzles). It can also braze combinations of heterogeneous materials using a gradient transition layer design to alleviate thermal expansion stress.
Can the specifications and dimensions of the furnace be customized?
Yes. We support custom configurations for the furnace's effective working area size, maximum temperature, working vacuum, gas cooling pressure, and other technical parameters based on your specific production requirements.
What monitoring and safety systems are integrated into the furnace?
The system features an integrated PLC with a program controller or computer interface, touch screen, and data recorder to monitor vacuum degree, temperature, and pressure in real-time. It also supports remote fault diagnosis, process tracing, and multiple safety protection mechanisms.
