Deep Vacuum Furnace Technology
Vacuum furnace plays an irreplaceable role in the production of mould. It is mainly used for ceramic firing, vacuum exercise, degassing of electric vacuum parts, annealing, brazing of metal parts, and ceramic-metal sealing.
Vacuum heat treatment of vacuum furnace can almost complete all heat treatment processes, such as quenching, annealing, tempering, carburizing, nitriding, gas quenching, oil quenching, nitrate quenching, water quenching, and vacuum brazing, sintering and surface treatment. Vacuum furnace has high thermal efficiency, can complete rapid heating and cooling, can complete no oxidation, no decarbonization, no carburization, can remove the phosphorus chip on the surface of the workpiece, and has the effect of degreasing and degassing, and then achieve the effect of external bright purification. Generally speaking, the processed workpiece is heated slowly in the furnace, the difference of internal heat temperature is small, the thermal stress is small, so the deformation is small. The qualified rate of products is high. The utility model can reduce the cost, have degassing effect, and then improve the mechanical performance and service life of the operation. Good working environment, safe operation, no pollution and pollution. The treated workpiece has no risk of hydrogen embrittlement, avoids hydrogen embrittlement on the surface 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 process has been more and more attention and use more and more widely.
Vacuum heat treatment refers to the inductive skill of combining vacuum technology with heat treatment, which refers to all and part of heat treatment process carried out in vacuum. China divides vacuum into low, medium, high and ultra-high vacuum.
