A high-temperature sintering furnace operates under a hydrogen-filled protective environment after vacuum pumping. Using medium-frequency induction heating, the tungsten crucible inside the induction coil reaches a high temperature, and heat is transferred to the workpiece through thermal radiation. It is suitable for research institutions and military applications, especially for powder sintering of refractory alloys such as tungsten, molybdenum, and their alloys.
The installation site should meet vacuum cleanliness requirements. The surrounding air must be clean, dry, and well-ventilated, and the working environment should avoid dust generation.
So, what should we pay attention to when using a vacuum sintering furnace?
- Check whether all components and accessories inside the control cabinet are complete and in good condition.
- The control cabinet should be installed on the designated foundation and securely fastened.
- According to the wiring diagram and the electrical schematic diagram, connect the main circuit and control circuit, ensure proper grounding, and verify wiring accuracy.
- As the manufacturer of aluminum nitride high-temperature sintering furnaces reminds, check that all movable electrical parts operate smoothly without sticking or jamming.
- Insulation resistance should not be less than 2 MΩ.
- All valves on the vacuum sintering furnace must be in the closed position.
- The control power switch should be in the “OFF” position.
- Turn the manual voltage-regulating knob counterclockwise to the initial position.
