Einrichtung zum Glühen und Einsatzhärten von Werkstücken.
EMI1.1
nehmenden Muffeln von umfangreichem Mauerwerk umgeben waren. Diese Konstraktioneu ermöglichen nur ein einseitiges Erhitzen der Muffe ! bzw. des Werkstückes und wurde dem letzteren durch das umgebende Mauerwerk viel Wärme entzogen und abgeleitet.
Bei der den Gegenstand der Erfindung bildenden Einrichtung werden die Werkstücke bzw. die mit denselben beschickten Muffeln unmittelbar mehrssammig und allseitig bestrahlt und gleichmässig erhitzt. Infolgedessen ist der Heizeffekt bei vollster Ausnutzung des Brennstoffes ein intensiver und wird eine wesentlich höhere Hitze erzielt.
Dies ermöglicht auch eine gedrängte Konstruktion der vorliegenden Einrichtung gegen- über den bestehenden Apparaten.
EMI1.2
hitztem Werkstück.
Die Muffel a' mit dem eingelegten Werkstück !/oder letzteres (a) unmittelbar ist von einem doppelwandigen Alantel b umgeben, dessen Innenmantel b'mit feuerfester Masse ausgekleidet ibt. Der Innenmantel b'und seine Auskleidung sind mit Durchbrechungen oder Perforierungen c versehen, in welche mit ihren Mündungen nach innen gerichtete

Device for annealing and case hardening of workpieces.
EMI1.1
The receiving muffles were surrounded by extensive masonry. These contractions only allow one-sided heating of the socket! or the workpiece and a lot of heat was withdrawn and dissipated from the latter by the surrounding masonry.
In the device forming the subject of the invention, the workpieces or the muffles charged with the same are irradiated directly from multiple sources and on all sides and heated evenly. As a result, when the fuel is used to the full, the heating effect is more intense and a significantly higher heat is achieved.
This also allows a compact construction of the present device compared to the existing apparatus.
EMI1.2
heated workpiece.
The muffle a 'with the inserted workpiece! / Or the latter (a) is immediately surrounded by a double-walled aluminum jacket b, the inner jacket b' of which is lined with refractory mass. The inner jacket b 'and its lining are provided with openings or perforations c into which their mouths point inwards
EMI1.3
connected, through which gas-air mixture flows into the annular space e) from where it passes through the nozzles c'in the combustion chamber f, is distributed there and, after ignition, the muffle a'bzw. the workpiece a is heated.
