1, The cause of serious oxidation in vacuum furnace:
Vacuum annealing furnace appears copper strip oxidation, indicating vacuum furnace leakage.
2, Solution for severe oxidation of vacuum furnace annealing
1, check whether the vacuum of the vacuum pump is normal, use a vacuum gauge to check the vacuum at the entrance of the vacuum pump to see if the vacuum limit of the pump can be reached. If it fails, change or repair, you can't change the pump.
2, use the
vacuum furnace to Jianlou instrument. If there is no leak detector (detector more expensive), acetone (ethanol) in the. The general leakage rate of 0.2Pa/h, it should be no problem.
