(Oil Quenching)Low Pressure Vacuum Carburizing Furnace

Vacuum quenching refers to the smooth quenching of parts. The quenching and cooling of parts are carried out in the vacuum furnace, and the quenching medium is mainly gas (such as inert gas), water and vacuum quenching oil. Vacuum quenching has been widely used in the quenching of various carburizing steels, alloy tool steels, high speed steels and stainless steels, as well as the solution treatment of various aging alloys and hard magnetic alloys.

There are two kinds of quenching in vacuum: gas quenching and liquid quenching. Gas quenching is that the workpiece is heated in vacuum and then cooled by high purity neutral gas (such as nitrogen) in the cooling chamber. High speed steel and high carbon and high chromium steel are suitable for gas quenching. Liquid quenching is to heat the workpiece in the heating chamber, move it to the cooling chamber, fill it with high purity nitrogen, and immediately send it to the quenching oil tank for rapid cooling. If high surface quality is needed, tempering and precipitation hardening after vacuum quenching and solution heat treatment should still be carried out in vacuum furnace.


Technical Data

1. Vacuum carburizing and vacuum oil quenching process can be switched seamlessly at any time to improve the utilization rate of equipment and realize multi-function.

2.Intelligent safety, green environmental protection, no open fire, no lampblack.

3. It is especially suitable for carburizing process treatment of special structural parts such as small holes, blind holes and narrow slots.

4.Stainless steel can achieve excellent carburizing effect without removingpassive film.

5.It can carburize at medium temperatureand high temperaturespeed, with highefficiency. 

6.No black structure, reduce fatigue sources,greatly improve the life of parts.

7. Precise vacuum low pressure carburizing process,s able operation, good reproducibility.
