Vacuum Hardening High-Strength Steels: Oil Vs. Gas
24/08/2007 The process is becoming increasingly popular because vacuum gas quench furnaces are generally less expensive to operate than vacuum oil quench furnaces and offer some further environmental advantages. The development of high pressure gas quenching was based on the principle that the denser the cooling medium, the more heat will be extracted from the load. By pressurizing, the quench gas ...

Vacuum Case Hardening what is Case Hardening Process ...
Vacuum Case Hardening. One of the most important processes of heat treatment is the case hardening or carburizing process. Parts are heated up to 1 000 °C and by adding specific gases (hydrocarbons) into the atmosphere of the furnace the part’s surface is enriched by absorbing carbon. Following this treatment the part is quenched in order to achieve the required properties, which results in ...

Vacuum Hardening – Cambridge Vacuum Engineering
The furnace is evacuated with vacuum pumps to operating pressure. This is commonly low vacuum (10-2 mbar range) for tool and high speed steels, higher vacuum levels (10-4mbar range) are used for materials more difficult to keep clean and bright, titanium for example. When the correct vacuum level has been achieved the charge is heated at a controlled rate to the preheat temperature.

Vacuum hardening - Premium Heat Treatment RÜBIG
Vacuum hardening is the hardening procedure for deformation sensitive precision or formed components and tools which make high demands on a clean, bright surface. Quenching is done by means of a gas stream with overpressure which can be adjusted in order to adapt the cooling conditions to the component requirements. The workpieces stay metallically blank and do not show impacts of

Overview of a Vertical Gas Quenching Vacuum Furnace
14/06/2019 A vertical vacuum furnace with gas quenching capability normally incorporates an external gas recirculating system to cool the inert quench gas used to extract heat from the load at the completion of the heating cycle. Depending on the application, the cooling gas is introduced into the chamber from sub-atmospheric pressure or, for fast quenching, at pressures up to 10 bar. The cooling gas

Vacuum furnace - Wikipedia
Vacuum furnaces are used in a wide range of applications in both production industries and research laboratories. At temperatures below 1200 °C, a vacuum furnace is commonly used for the heat treatment of steelalloys. Many general heat treating applications involve the hardening and tempering of a steel part to make it strong and tough through service. Hardening involves heating the steel to a predetermined temperature

Vacuum Furnace Quenching System: The Role of Gas
Sticking with a high-pressure stream of nitrogen or helium, a vacuum furnace, one that’s equipped with a quenching chamber, receives its velocity-delivered stream of quenching gas. Of great benefit here, the gas cooling action doesn’t cause the metal to deform or experience dimensional changes. That’s a feature that liquid quenching can’t duplicate, by the way. Also, the process is ...
