Precautions for use of vacuum atmosphere tube furnace

Specific precautions for vacuum atmosphere tube furnace are as follows:
1. Ultimate vacuum degree and leakage rate (related to furnace sealing)
2. Time to pump the extreme vacuum (related to the quality of mechanical pump and roots pump)
3. Fast heating speed (sometimes required by the process)
4. Cooling rate (production efficiency) from high temperature to room temperature, and whether there is fast cooling device
5. The Zui high temperature that the furnace can reach and the Zui high use temperature of the furnace (the two are different)
6. Specification and model of vacuum gauge used.
7. Whether the process gas can be passed is related to the need of use. If the sintered product sometimes needs some gas, this is necessary.
8. The material of the heating element, the wiring method and insulation material between the heating element and the power supply of the vacuum tube furnace must be high-purity graphite if it is graphite, and the insulation material must be good, and the wiring structure is not easy to cause short circuit.
9. The glue collector is auxiliary, but it is equally important. Generally, the products will be mixed with glue or paraffin, so you should pay attention to that the cleaning port of the wax collecting device must be convenient to open. If you use wax and other molding agents that are solid at normal temperature, the wax collecting device must be able to heat, or it must be blocked.
