What is the application of vacuum furnace in heat treatment?

The vacuum furnace is used not only for ordinary workpiece quenching and tempering, annealing and normalizing, and can carry out chemical heat treatment such as vacuum carburizing (including vacuum carbonitriding), vacuum ion carburizing and glow ion nitriding, and complete sintering, brazing and vacuum coating metal, vacuum carburizing layer has uniform and reproducible advantages good, clean and bright surface gas consumption, saving source etc.. According to the cooling medium using vacuum furnace cooling, vacuum furnace is divided into cold oil gas quenching vacuum furnace, vacuum furnace, an oil cooling oil cooling vacuum furnace and gas cooling vacuum furnace several; according to the structure of the form is divided into single rooms, double rooms, three rooms and continuous furnace etc..
