Vertical gas pressure sintering furnace for loading large-size aerospace ceramic products:
Vacuum protective atmosphere heat treatment method to the choice of gas filling. When using the partial pressure of heating vacuum heat treatment back filling gas should choose the neutral or inert gases, high purity hydrogen, helium, nitrogen and argon gas, such as common gases, four gas cooling speed from fast to slow, in turn, for hydrogen, helium, nitrogen and argon. In the air as the cooling speed of 1, the hydrogen, helium, nitrogen, argon and air cooling speed ratio of 7, 6, 0.99, 0.7, respectively. Under any pressure, hydrogen has the maximum heat transfer capacity and maximum cooling speed, can be used for graphite as heating and insulation components of vacuum furnace.
In order to achieve the loading of large-size ceramic products,the equipment adopt a vertical structure design and is used for the sintering of high-temperature resistant aerospace components.
