    Die Verbindungsönnungen zwischen   den Kanälen 9 und 10 und den   Hohlräumen 7   und 8 müssen in ähnlicher Weise zugedeckt werden. Um die Sicherheit gegen Eindringen von Luft durch die Kanäle in den Ofenraum zu erhöhen, werden die Öffnungen 12 mit, geeigneten, leicht schmelzoder brennbaren Materialien zugestopft. 



   Die Wirkungsweise der Vorrichtung ist ohne weiters klar :
Entsteht ein Riss in der inneren Wand des Tiegels, sei es infolge von   Ausdehnungs-oder     Kontraktionserscheinungen,   sei es infolge zu weitgehender Aufressung durch die Schlacke, so

 Kanälen 9 erreicht, wo es die dünne   Abdeckung   leicht durchschmilzt und nun freien Weg durch die Kanäle 9 und 10 zu der Rinne 11 und von dieser durch die   Öffnungen 12,   das dieselben zustopfende Material verbrennend, ins Freie findet. Wie aus Fig. 2 ersichtlich, werden die Offnungen 12 teils am Ende der Kanäle   10,   teils zwischen diesen Kanälen, und zwar immer an    solchen   Stellen der Rinne 11 angebracht, wo das ausfliessende heisse Metall keine schmelzbaren Teile des Ofens treffen kann. 



   Sollte die Gefahr bestehen, dass der    Metalstrahi infolge   einer Ausfressung der   Öffnung   12 oder aus anderen Ursachen schief austreten könnte, werden die Metallteile noch durch Bleche. welche mit feuerfester Masse belegt sind,   geschützt   oder werden die Metallteile selbst mit feuerfesten Steinen oder Masse bedeckt.

 angebrachten Grabe oder grossen Kokille zuführen. 



   Besteht die Möglichkeit, dass das Metall beim   Ilereinfalleii   in die Grube herumspritzen   k. u. n. so werden die dem Spritzen   ausgesetzten Teile mit feuerfesten Steinen oder Mörtel bedeckt.

 EMI2.1
 



    The connection openings between the channels 9 and 10 and the cavities 7 and 8 must be covered in a similar manner. In order to increase the security against ingress of air through the channels into the furnace space, the openings 12 are plugged with suitable, easily meltable or combustible materials.



   The mode of operation of the device is immediately clear:
If a crack arises in the inner wall of the crucible, be it due to expansion or contraction phenomena, or due to excessive erosion by the slag, then
 EMI2.2
 Reached channels 9, where it easily melts through the thin cover and now finds a free path through the channels 9 and 10 to the channel 11 and from this through the openings 12, burning the same clogging material into the open. As can be seen from FIG. 2, the openings 12 are made partly at the end of the channels 10, partly between these channels, and always at those points of the channel 11 where the hot metal flowing out cannot hit any fusible parts of the furnace.



   If there is a risk that the metal beam could emerge at an angle as a result of the opening 12 being eroded or for other reasons, the metal parts are still through sheets. which are covered with refractory mass, protected or the metal parts themselves are covered with refractory stones or mass.
 EMI2.3
 feed in a ditch or large mold.



   Is there a possibility that the metal will splash around into the pit when the Ilfall falls? u. n. so the parts exposed to the spraying are covered with refractory bricks or mortar.
