The invention relates to a device (30) for the extraction and the transfer of granular mineral materials at high temperature contained in a first enclosure including a fixed upper part (32) and a mobile lower part (34) delimiting a duct (36), the mobile lower part (34) being movable in a determined direction (50) between a advanced position and a retracted position, and vice versa, to allow the flow of the granular mineral materials in the duct (36). The device further includes means (78, 80) for moving and guiding the mobile part (34) relative to the fixed part (32). The fixed part (32) and the mobile part (34) each comprise a metal outer shell (38, 58), and an inner shell (40; 60) made by stacking at least a first coating (42; 62) of thermally insulating material mounted on the metal outer shell (38; 58), and a second coating (44; 64) of refractory material mounted on the first coating (42, 62).

Embodiments of the present invention relate to a handling device for handling a metal component part between a furnace device and a further processing device. The handling device comprises a temperature-control chamber, in which the metal component part can be inserted, and a conveying device. The temperature-control chamber comprises a temperature-control unit that adjusts a temperature in the temperature-control chamber. The temperature-control chamber can be conveyed between a receiving position, in which the metal component part can be conveyed from the furnace device into the temperature-control chamber, and a dispensing position, in which the metal component part can be conveyed from the temperature control chamber to the further processing device. The conveying device is configured in such a manner that the metal component part can be conveyed in the receiving position by means of the conveying device between the furnace device and the temperature-control chamber and that the metal component part can be conveyed in the dispensing position by means of the conveying device between the temperature-control chamber and the further processing device.

A device for heat treatment is provided. The device includes at least one processing chamber arranged in an elongated housing having a heating device and having a transport system for continuous transport of material to be treated through the processing chamber. The transport system has two parallel endless conveyor belts spaced from each other and a plurality of cylinders made of quartz glass that bridge the distance between the conveyor belts. The cylinders are supported on these belts and the material to be treated is supported on the cylinders for the heat treatment. The cylinders are designed as twin tubes, formed by two tubular compartments separated from each other by an intermediate partition. Each tubular compartment has a longitudinal axis and is connected rotation-free at its end with the conveyor belts.
