What is a vacuum heat treatment furnace?


    Vacuum heat treatment, that is, the combination of vacuum technology and heat treatment, refers to the combination of all the parts of the heat treatment process under vacuum. China divides vacuum into low, medium, high and ultra-high vacuum. At present, most vacuum heat treatment furnaces have a working vacuum of 1.33~1.33×10ˉ³ Pa.
    Vacuum heat treatment can almost achieve all heat treatment processes, such as quenching, annealing, tempering, carburizing, nitriding, gas quenching, oil quenching, nitrate quenching, water quenching, etc. in the quenching process, vacuum brazing, Sintering, surface treatment, etc. The vacuum heat treatment furnace has high thermal efficiency, can realize rapid temperature rise and temperature drop, can realize no oxidation, no decarburization, no carburization, can remove the phosphorous chips on the surface of the workpiece, and has the functions of degreasing and degassing, thereby achieving the effect of surface bright purification.
    Generally, the workpiece to be processed is slowly heated in the furnace, the internal heat temperature difference is small, the thermal stress is small, and the deformation is small. The product qualification rate is high. It can reduce the cost and degassing, thus improving the mechanical performance and service life of the work. Good working environment, safe operation, no pollution and pollution. The workpiece to be processed has no hydrogen embrittlement hazard, and the titanium and refractory metal shells prevent surface hydrogen embrittlement, and the stability and repeatability of the vacuum heat treatment process are good. The advantages of this series, the development of vacuum heat treatment equipment and processes are getting more and more attention and application.
