v\ PATENTAMT.v \ PATENT OFFICE.

Eine Birne, welche ähnlich einer Bessemer-Birne zum Vorfrischen von flüssigem, aus einem Hoch- oder Coupolofen entnommenen Roheisen dienen soll (das dann behufs Weiterverarbeitung zu Flufseisen in einen Herdofen abgegeben wird), mufs einen sehr grofsen inneren Raum besitzen, um ein Ueberkochen zu verhindern; infolgedessen erhält die Haube eine verhältnifsmiifsig grofse Höhe. Die vorliegende Erfindung bezieht sich nun darauf, bei solchen Birnen eine besondere, tiefer liegende Oeffhung zum Ein- und Ausgiefsen anzubringen, so däfs die obere Oeffnung nur zum Entweichen der Gase dient.A pear, which is similar to a Bessemer pear for pre-freshening liquid, from a Pig iron removed from the blast furnace or coupole furnace is to be used (which is then used for further processing to flux iron in a hearth furnace) must be very large have internal space to prevent overcooking; as a result, the hood gets a comparatively great height. The present invention now relates to to make a special, deeper-lying opening for pouring in and out of such pears, so the upper opening should only be used for escape serves the gases.

Auf der beiliegenden Zeichnung ist eine derart gebaute Vorfrischbirne veranschaulicht, und zwar zeigt:A pre-freshener built in this way is illustrated in the accompanying drawing, and although shows:

Fig. ι einen Verticalschnitt senkrecht zur Drehachse,Fig. Ι a vertical section perpendicular to Axis of rotation,

Fig. 2 einen Verticalschnitt längs der Drehachse. 2 shows a vertical section along the axis of rotation.

Wie aus Fig. 1 ersichtlich, ist P der besondere Ein- bezw. Ausgufs, während die Haube L nur das Ueberkochen verhindert und zum Entweichen der Gase dient. Dieser Einbezw. Ausgufs P besitzt eine Oefthung O (Fig. 1 und 2), welche in der Wand der Birne eng ist und sich nach oben zu stark erweitert, um endlich in einen Schnabel Q. auszulaufen. Durch diese eigenartige Gestaltung des besonderen Ein- und Ausgusses wird folgender Effect erzielt: Das kochende Metall steigt im Innern der Birne höher als in diesem Aufsenraum, weil es dort noch mit Gasen vermischt ist, welche hier nur in geringem Mafse eintreten und rascher entweichen, so dafs das specjfische Gewicht dieses mehr entgasten Eisens also höher ist. Das durch die Bewegung im Innern hervorgerufene Auf- und Niederwogen der durch O verbundenen Metallbäder dient ferner dazu, ein Erstarren derselben zu verhindern.As can be seen from FIG. 1, P is the special one or more. Spout, while the hood L only prevents overcooking and serves to escape the gases. This Einbezw. The outlet P has an opening O (Figs. 1 and 2) which is narrow in the wall of the pear and widens too much towards the top to finally run out into a beak Q. The following effect is achieved through this peculiar design of the special spout: The boiling metal rises higher in the interior of the pear than in this outer space, because there it is still mixed with gases, which enter here only to a small extent and escape more quickly, so that the specific weight of this more degassed iron is therefore higher. The rising and falling of the metal baths connected by O , caused by the movement inside, also serves to prevent them from solidifying.

Claims (1)

Patent-Anspruch:Patent claim: Birne, insbesondere zum Vorfrischen, dadurch gekennzeichnet, dafs sie aufser der Ausblasemündung eine zum Einführen und Ausgiefsen des Eisens dienende Oefthung nahe dem Boden besitzt, welche von einem so hohen Mantel umgeben ist, dafs das innerhalb desselben befindliche Eisen einen hydrostatischen Äbschlufs für die Birne bildet.Pear, especially for pre-freshening, characterized in that it is located on the blow-out mouth a hole near the ground for introducing and pouring out the iron which is surrounded by a mantle so high that what is inside it Iron forms a hydrostatic closure for the pear.
