Verfahren zum Zementieren von Eisen- und Stahl gegenständen mittels um die Gegenstände herumgeführter Gase.
Den Gegenstand vorliegender Erfindung bildet ein Verfahren zum Zementieren von Eisen- und Stahlgegenständen, darin bestehend, dass man die Eisen- und Stahl gegenstände in Schlacke oder Sand oder in einem anderen indifferenten körnigen Stoff einbettet, vorerst bis zur Rotglut erhitzt, dann die zum Zementieren verwendeten Gase durch dieses Material hindurchpresst.
Durch die Einbettung der zu zementierenden Gegenstände in einem indifferenten, körnigen Stoff wird erreicht, dass man den Zementiervorgang ausser durch Zuführung der
EMI1.1
beeinflussen kann, und zwar bedeutend zuverlässiger als durch die Regelung der Gaszufuhr mittels Hahne, Ventile und dgl. bei den bekannten Zementierverfahren.
Ein weiterer Vorteil des Verfahrens nach der Ernndung beätnht darin, dass man die zu härtenden Gegenstände nicht unbedingt in einem gasdicht verschlossenen Raum zu erhitzen braucht, was besonders bei dem Härten kleiner Gegenstände wichtig ist.
Eine vorteilhafte Ausführung des Verfahrens ist die folgende : Die zu zementierenden
EMI1.2
Entwicklung der zum Einsatzharten verwendeten Gase eingeleitet, so dass. wenn die im ersten Behälter befindlichen Gegenstände auf Hotglut erhitzt sind, aus dem anderen Behälter die Gase eingeführt werden können.

dieser Weise lässt sich besonders das Zementieren kleinerer Gegenstände vorteilhaft durchführer.

Method of cementing iron and steel objects by means of gases circulated around the objects.
The subject of the present invention is a method for cementing iron and steel objects, which consists in embedding the iron and steel objects in slag or sand or in another indifferent granular material, first heating them to red heat, then heating them to the cement Forcing gases through this material.
By embedding the objects to be cemented in an indifferent, granular substance it is achieved that the cementing process is carried out except by supplying the
EMI1.1
can influence, and that much more reliably than by regulating the gas supply by means of taps, valves and the like. In the known cementing process.
Another advantage of the method according to the invention is that the objects to be hardened do not necessarily have to be heated in a gas-tight sealed space, which is particularly important when hardening small objects.
An advantageous embodiment of the method is as follows: The ones to be cemented
EMI1.2
Development of the gases used for hard use initiated, so that when the objects in the first container are heated to hot embers, the gases can be introduced from the other container.
EMI1.3
In this way, especially the cementing of smaller objects can be carried out advantageously.
EMI1.4
