Knowledge of vacuum heat treatment

Time:2015-06-17 09:02
1. Titanium vacuum furnace process, should not use nitrogen as the cooling gas, because titanium and nitrogen at high temperatures, to form titanium nitride gold.
2. Vacuum furnace part in all activities in connection rubber O-ring seals the connection, this section are cooled by water.
3. Hardening of the workpiece in a vacuum, you should use a vacuum quenching oil, this oil has a lower saturation vapor pressure.
4. Vacuum furnace maintenance should charge under vacuum or nitrogen status, avoid breathing normally when not absorb moisture.
5. Domestic vacuum furnace pressure rise rate should not exceed 1.33Pa / h, certain standards for foreign companies 0.67Pa / h
6. Vacuum heating to radiation main piece in the furnace should be kept spacing.
7. Heating process, the workpiece material and the furnace will be deflated to a vacuum degree drop.
8. The heating temperature vacuum annealing, vacuum annealing, vacuum and vacuum aging solution treatment temperature is generally the same as conventional treatment and heating.
9. Vacuum furnace should have a fast-cooling device. Cooling water pressure should be greater than 0.2Mpa, traffic should be adjustable.
