The vacuum sintering furnace is primarily used for the sintering process of semiconductor components and power rectifier devices. It can perform vacuum sintering, gas-protected sintering, and conventional sintering. As an innovative piece of equipment in the semiconductor-specific equipment series, it features a novel design, easy operation, and compact structure, allowing multiple processes to be completed on a single device. It can also be used for vacuum heat treatment, vacuum brazing, and other processes in various fields.
A high-vacuum sintering furnace works under hydrogen protection after evacuation. It uses the principle of medium-frequency induction heating to generate high temperatures in the tungsten crucible within the coil. The heat is then transmitted to the workpiece through thermal radiation. It is suitable for research institutes and military-industrial units for sintering powder-formed refractory alloys such as tungsten, molybdenum, and their alloys. The installation site for the electric furnace should meet vacuum cleanliness standards, with clean, dry air and good ventilation. The workspace should minimize dust generation.
Daily Usage Tips for Vacuum Sintering Furnace:
- Check that all components and accessories in the control cabinet are complete and in good condition.
- Install the control cabinet on the designated foundation and secure it.
- Connect the external main and control circuits according to the wiring diagram and electrical schematic, ensuring reliable grounding and correct wiring.
- Ensure all movable electrical parts operate smoothly without jamming.
- The insulation resistance should not be lower than 2 MΩ.
- All valves of the vacuum electric furnace must be in the closed position.
- Set the control power switch to the off position.
- Turn the manual voltage adjustment knob counterclockwise.
- Set the alarm button to the on position.
- Connect the circulating cooling water according to the layout diagram. It is recommended to install a backup water supply (tap water can be used) at the main inlet/outlet to prevent damage to the sealing rings in case of circulation failure or power outage.
