Difference between atmosphere furnace and vacuum furnace

The difference between atmosphere furnace and vacuum furnace, vacuum thermal disposal skills, namely, the comprehensive skills of vacuum skills and thermal disposal skills, are all and part of the thermal disposal process in the vacuum form. China divides vacuum into four types: low, medium, high and ultra-high vacuum. At present, the vacuum degree of most vacuum heat treatment intermediate frequency furnaces is 1.33~1.33 x 10-3pa.
The difference between the atmosphere furnace and the vacuum furnace is that the vacuum thermal treatment can simply complete all the thermal treatment processes, such as quenching, annealing, tempering, carburizing, nitriding, gas quenching, oil quenching, nitrite quenching, water quenching, etc. in the quenching process, can also be vacuum brazing, sintering, appearance disposal. The difference between the atmosphere furnace and the vacuum furnace is that the vacuum heat treatment furnace has high thermal efficiency, which can achieve rapid leveling and cooling, no oxidation, no decarburization, no carburization, can go to the appearance of the lost workpiece phosphorus chip, and degreasing degassing effect, and then reach the appearance of light purification results. The difference between the atmosphere furnace and the vacuum furnace, generally speaking, the workpiece is disposed of in the vacuum induction furnace heating slow, the internal heat temperature difference is small, the thermal stress is small, so the deformation is small. The product has a high qualification rate. Can reduce cost, have degassing effect, and then improve the mechanical function of the task and service life. Good mission condition, safe operation, no pollution and pollution. There is no risk of hydrogen embrittlement in the disposed workpiece. It can avoid hydrogen embrittlement on the titanium material and refractory metal shell. The vacuum thermal treatment process has good invariability and repeatability. This series of advantages, the development of vacuum heat treatment equipment and technology is more and more attention and use more and more widely. The above is the difference between atmosphere furnace and vacuum furnace. I hope it is helpful to you.
