Vacuum furnace technology
Vacuum furnace plays an irreplaceable role in mold production, mainly used in ceramic firing, vacuum training, electrical vacuum parts degassing, annealing, brazing of metal parts, and ceramic-metal sealing.
Vacuum heat treatment of vacuum furnace can almost complete all the heat treatment processes, such as quenching, annealing, tempering, carburizing, nitriding, gas quenching, oil quenching, nitrate quenching, water quenching and so on, but also can be carried out vacuum brazing, sintering, surface treatment. Vacuum furnace has high thermal efficiency, can complete rapid heating text cooling, can complete no oxidation, no decarbonization, no carburization, can remove the surface of the workpiece phosphorus chip, and has degreasing degassing effect, and then achieve the effect of surface bright purification. Generally speaking, the processed workpiece is slowly heated in the furnace, the internal thermal temperature difference is small, the thermal stress is small, so the deformation is small. The product has a high pass rate. It can reduce the cost and degassing effect, and then improve the mechanical performance and service life of the operation. The operation environment is good, the operation is safe, no pollution and public nuisance. The treated workpiece has no risk of hydrogen embrittlement, avoids hydrogen embrittlement of titanium and refractory metal shell, and has good stability and repeatability of vacuum heat treatment process. This series of advantages, the development of vacuum heat treatment equipment and technology has been more and more attention and more widely used.
Vacuum heat treatment is a combination of vacuum skills and heat treatment of inductive skills, refers to all and part of the heat treatment process in a vacuum state. Vacuum is divided into low, medium, high and ultra-high vacuum in China.
