- the chassis is advantageously dependent on the operational Need rail bound or by embedded in the floor Induction loops can be freely steered. For easy loading of the workpieces from a treatment chamber into the transport chamber or To achieve the other way round, it has also proven useful if the means of discovery Unload the workpieces have a loading fork that is horizontal and is vertically movable.
- Such a heat treatment plant is related with the previously described device for transporting metallic Benefit from workpieces. By providing the lock it is ensured that the workpieces are protected from environmental influences protected between a treatment chamber and the transport chamber can be shipped.
- the invention Heat treatment plant is characterized by great flexibility Regarding the transport of the workpieces between the individual Treatment chambers from, which also results in a relatively high Throughput performance and therefore an economically efficient one Procedure can be achieved.
- the lock can be evacuated separately, so that it regardless of the type of treatment chamber, for example Vacuum furnace or atmospheric furnace is to be operated. It is also on this Possible, the lock already during the transport of the Transport chamber to the corresponding treatment chamber evacuate to ensure that the process runs as quickly as possible. ever depending on the application, it is also conceivable that the lock through a vacuum pump arranged on the transport chamber is evacuated.
- the lock has a drive through which the loading door of the Transport chamber is actuated. This contributes to a particular lightweight design of the transport chamber and thus too relatively low cost of conveying the workpieces between the individual treatment chambers at. In terms of one The greatest possible variability in the design of the heat treatment is Treatment chamber expediently a vacuum oven Atmospheric furnace or a cooling chamber.
- the solution to the above problem is at a method with the features mentioned above characterized in that the vacuum-tight transport chamber a vacuum protecting the workpieces from environmental influences is evacuated and the workpieces in this vacuum from one Treatment chamber to be transported to the next.
- the transport of the workpieces in a given vacuum evacuated transport chamber has mainly been used for the transportation of heated a relatively high temperature of, for example, 1000 ° C Workpieces turned out to be extremely advantageous.
- Inert gas can in this way be an often undesirable one Avoid temperature drop.
