Vacuum heat treatment equipment

Vacuum heat treatment technology and vacuum heat treatment that combines two professional comprehensive technology means full and partial heat treatment process conducted in a vacuum. China will be a vacuum into low, medium, high and ultra-high vacuum. Most of the current working vacuum in the vacuum heat treatment furnace 1.33 ~ 1.33 × 10 ˉ ³ Pa.
 
    Vacuum heat treatment can achieve almost all of the heat treatment process, such as hardening, annealing, tempering, carburizing, nitriding, hardening process can be achieved in gas quenching, oil quenching, nitrate quenching, water quenching, etc., can also be vacuum brazing, sintering, surface treatment. High vacuum heat treatment furnace thermal efficiency, enabling fast heating and cooling can be achieved without oxidation, decarburization, no carburizing, phosphorus can be removed surface debris, and have skimmed degassing and so on, so as to achieve bright surface purification effect. Generally, the workpiece is heat treated in the furnace slowly heat the temperature difference is small, a small thermal stress, and thus deformation. Product qualification rate. Cost can be reduced, unless there is air, thereby improving the mechanical properties and working life. Work environment, safe operation, no pollution and public nuisance. Workpiece to be treated no risk of hydrogen embrittlement of titanium and refractory metal shell to prevent surface embrittlement, vacuum heat treatment process stability and reproducibility. The advantage of this series, the development of vacuum heat treatment equipment and processes to be more and more attention and more and more widely.
