Apart from having to use an airlock, this installation does not prevent the oxidation of the surface of the parts of the charge, the pollution and the Oven cooling during the complete work cycle.
- EP-A-893 510 which does not constitute a published prior art before the filing date, discloses an installation for the automatic heat treatment, including seals. However, both sets of this installation are stationary and it is therefore not possible to put any tray next to an oven. In addition, this construction does not maintain the watertightness of ovens and bins during a work cycle.
- an aim of the The present invention is to provide an installation of heat treatment does not need to cool the oven, and to treat the parts including their transfer without surface oxidation and without gas pollution Oven treatment or without pollution of the oven vacuum during the entire work cycle.
