About Vacuum Ovens
In vacuum ovens, the heat-treating process takes place inside a vessel that is airtight. This allows a vacuum to be drawn inside the vessel. The entire heat-treating process can take place under vacuum or precisely controlled atmospheres can be introduced. Heat treating under vacuum can: prevent surface reactions, such as oxidation or decarburization; remove surface contaminants such as oxide films and residual traces of lubricants; add a substance to the surface layers of the work; remove dissolved contaminating substances from metals by means of degassing. Ovens are built of several kinds of high temperature (refractory) materials to hold the process material and hold in the heat without breaking down during the several months that they usually run. Ovens are lower temperature (usually <1400 degrees F) thermal processing units, usually without refractory insulation.
Important parameters to consider when specifying vacuum ovens include temperature range, capacity and pressure range. The temperature range is the maximum temperature at which the unit may operate and still maintain rated performances. The capacity refers to the capacity of the heated interior space of the unit. Vacuum ranges for vacuum ovens can be rough or low, (< 760, > 1 torr), medium (< 1, >10-3 torr), high vacuum (< 10-3, >10-8 torr), ultra-high vacuum (< 10-8 torr), and elevated pressures (> 760 torr).
