5518 Partial Pressure Sintering Furnace For Silicon Nitride / Aluminum Nitride / Silicon Carbide

5518 Partial Pressure Sintering for silicon nitride,aluminum nitride,silicon carbide

    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. But, for high carbon steel grade, the cooling stage of high temperature (above 1050 ℃) may cause slight decarbonization; Used for high strength steel has the risk of hydrogen embrittlement. Using hydrogen as coolant supply system should be sealed and reliable, complete cooling after operation, should be timely discharge of hydrogen, and filling the nitrogen, may open the oven door, otherwise, has caused the risk of explosion.
