 gehärteter Stahlteile ist nun besonders darauf zu achten, dass die Erwärmung der Teile möglichst gleichmässig in kürzester Zeit erfolgt. Die bisher in Gebrauch befindlichen Einrichtungen zum Anlassen von Stahlteilen entsprechen diesen Bedingungen nur unvollkommen. 



  In vielen Fällen benutzt man zum Anlassen Ölbäder, die durch Kohlen-, Öl-oder Gasfeuerung auf die entsprechende Anlasstemperatur gebracht werden. Nachdem das in einem Tiegel befindliche Öl genügend erhitzt ist, werden die anzulassenden Teile in einem Drahtkorb oder einer sonstigen Vorrichtung in das Ölbad eingehängt und verbleiben darin so

  Method and device for tempering hardened metal objects.
 EMI1.1
 For hardened steel parts, special care must be taken to ensure that the parts are heated as evenly as possible in the shortest possible time. The facilities for tempering steel parts that have been in use up to now only incompletely meet these conditions.



  In many cases, oil baths are used for tempering, which are brought to the appropriate tempering temperature using coal, oil or gas. After the oil in a crucible has been sufficiently heated, the parts to be tempered are hung in a wire basket or some other device in the oil bath and remain there

gehend gleichmässig zu erwärmen. Ausserdem nimmt die Erwärmung der anzulassenden Teile lange Zeit in Anspruch, weil durch die eingeführten kälteren Teile dem Öl eine grosse Wärmemenge entzogen wird, welche nur durch Wärmeleitung des umgebenden Öles ersetzt werden kann. EMI1.3 Zeichnung dargestellte Vorrichtung dient, werden diese Nachteile beseitigt. going to heat evenly. In addition, the heating of the parts to be tempered takes a long time, because a large amount of heat is withdrawn from the oil by the colder parts introduced, which can only be replaced by conduction of the surrounding oil. EMI1.3 The device shown in the drawing is used, these disadvantages are eliminated. Die anzulassenden Teile werden genau wie früher mittels Drahtkorbes oder sonstiger Vorrichtungen in einen möglichst isolierten Behälter b eingehängt, in den das in einem besonderen Apparat e auf Anlasstemperatur erwärmte Öl von irgendeiner Seite her unter Druck eingeführt wird. Das warme Öl durchströmt mit entsprechender Geschwindigkeit den Behälter und gibt seine Wärme an die anzulassenden Teile ab. Durch das beständig nachgedrückte warme Öl wird das sich nur um wenige Grade abkühlende 01 stetig verdrängt und durch eine Absaugevorrichtung p in den Olerhitzej ; zwecks Wiedererwärmung auf die Anlasstemperatur zurückgeführt. EMI1.4 während der Arbeitsdauer zu erhalten. As before, the parts to be tempered are hung in a container b, which is as insulated as possible, using a wire basket or other device, into which the oil, heated to the tempering temperature in a special device e, is introduced under pressure from any side. The warm oil flows through the container at a corresponding speed and transfers its heat to the parts to be started. The oil, which is only cooled by a few degrees, is steadily displaced by the constantly pushed in warm oil and released into the oil heatj by a suction device p; returned to the tempering temperature for reheating. EMI1.4 to receive during the working period. PATENT-ANSPRÜCHE : EMI1.5 PATENT CLAIMS: EMI1.5 2.

The method according to claim i, characterized in that the liquid is conveyed through the starting tank in a controllable manner by means of a suction, pressure or similar pump. 3. Vorrichtung zur Ausführung des Verfahrens nach den Ansprüchen i und 2, dadurch gekennzeichnet, dass in eine Flüssigkeitszu-und-ableitung des Anlasshehälters ein Flüssigkeitserhitzer und eine Pumpe unmittelbar eingeschaltet sind, von der die erhitzte Flüssigkeit in regelbarem Masse im geschlossenen Kreislauf gefördert wird. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. 3. Apparatus for carrying out the method according to claims i and 2, characterized in that a liquid heater and a pump are directly switched on in a liquid supply and discharge line of the starter holder, by which the heated liquid is conveyed in a controllable mass in a closed circuit. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
