Description
Kupolofen mit Vorherd. Die Erfindung betrifft Kupolöfen mit Vorherd, bei denen zwischen dem eigentlichen Ofen und dem Vorherde ein schräg von unten nach oben verlaufender Verbindungskanal angeordnet ist. Von den bekannten Ofen dieser Art unterscheidet sich der Erfindungsgegenstand dadurch, daß bei ihm der Verbindungskanal an der Schachtseite mit einer schmelzbaren Platte abgeschlossen ist.Cupola furnace with forehearth. The invention relates to cupolas with forehearth, in the case of those between the actual furnace and the forehearth an oblique from below to connecting channel running above is arranged. From the well-known furnace this one Type differs from the subject matter of the invention in that it has the connecting channel is closed on the shaft side with a fusible plate.
Durch diese Platte wird der von dem .eigentlichen Ofen nach dem Vorherde führende Abflußkanal so lange verschlossen gehalten, bis der Spiegel des geschmolzenen Metalls und die auf demselben schwimmende Schlackenschicht den oberen Rand der inneren Mündung des Kanals überschritten haben. Wenn dies geschehen ist, so schmilzt die Platte ab, und hierdurch wird der Abfluß nach dem Vorherdefreigegeben. Es wird also auf diese Weise verhindert, daß die Schlacken in den Abflußkanal eintreten.This plate is used by the actual furnace after the forehearth leading drainage channel kept closed until the level of the melted Metal and the layer of slag floating on the same the upper edge of the inner Have crossed the mouth of the canal. When this is done, it melts Plate off, and this releases the drain after the forehearth. So it will in this way prevents the slags from entering the drainage channel.
Die Zeichnung stellt den. Erfindungsgegenstand in einem Ausführungsbeispiele dar, und zwar zeigt Abb. z einen teilweisen Längsschnitt durch einen Kupolofen, Abb. a einen Querschnitt.The drawing represents the. Subject matter of the invention in one exemplary embodiment Fig.z shows a partial longitudinal section through a cupola furnace, Fig.a a cross section.
Von dem Schachte a führt der ansteigende Abflußkanal b in den Vorherd d. Nach der Schachtseite hin ist der Kanal b während des Anblasens durch eine Metallplatte e verschlossen. Diese hält zunächst die sich bildende Schlacke und das Metall zurück. Die Platte e wird so stark gewählt, daß sie der Hitze Stand hält, bis die auf dem steigenden Metallbade schwimmende Schlacke die Höhe der inneren Mündung des Kanals b überschritten hat. Dadurch wird das sich in dem Vorherde d sammelnde Metall von Schlacken vollkommen frei gehalten. The rising drainage channel b leads from the shaft a into the forehearth d. On the shaft side, the channel b is closed by a metal plate e during the blowing process. This initially holds back the slag that forms and the metal. The plate e is chosen so strong that it withstands the heat until the slag floating on the rising metal bath has exceeded the level of the inner mouth of the channel b. As a result, the metal that collects in the forehearth d is kept completely free of slag.
Der Kanal b endigt innen an einer Aussparung c in der Wand des Schachtes a. Hierdurch wird eine gute Befestigung der Platte e ermöglicht, und außerdem bildet die Aussparung c eine Staukammer, in der das flüssige Metall, bevor es in den Kanal b eintrtt, zur Ruhe kommt.The channel b ends on the inside at a recess c in the wall of the shaft a. This enables a good fastening of the plate e, and also forms the recess c a storage chamber in which the liquid metal before it enters the channel b enters, comes to rest.
