Description

Vorrichtung zur Ausnutzung der Konverterabgase. Die Erfindung betrifft eine Vorrichtung zur Ausnutzung der Konverterabgase. Diese besteht darin, daß ein Konverter mit einem Schacht durch einen Drehrohrofen derart verbunden ist, daß durch das Drehrohr Erz und Kalk in regelbarer Menge und Beschaffenheit dem Konverter zugeführt werden, und daß die Konverterabgase in das Drehrohr eingeleitet werden, um in bekannter Weise zur Reduktion und Vorwärmung der Erze zu dienen. Diese Vorrichtung ermöglicht eine besonders vorteilhafte Ausnutzung der Konverterabgase.Device for utilizing the converter exhaust gases. The invention relates to a device for utilizing the converter exhaust gases. This is that a Converter is connected to a shaft by a rotary kiln in such a way that through the rotary kiln ore and lime are fed to the converter in adjustable quantities and properties be, and that the converter exhaust gases are introduced into the rotary tube in order to be known Way to reduce and preheat the ores. This device enables a particularly advantageous use of the converter exhaust gases.

Die Zeichnung zeigt eine beispielsweise Ausführung der Vorrichtung in teilweisem Längsschnitt. Die Erze nebst Zuschlägen werden in dem Schacht A aufgegeben und durch das zwischen Schacht und Konverter eingeschaltete geneigte Drehrohr B in regelbarer Menge in den Konverter D gebracht. C ist ein Zwischenstück zur Verbindung zwischen Drehrohr und Konverter.The drawing shows an example of an embodiment of the device in partial longitudinal section. The ores and aggregates are fed into shaft A. and through the inclined rotary tube B inserted between the shaft and the converter brought into the converter D in a controllable amount. C is an intermediate piece for connection between rotary kiln and converter.

Zum Füllen «zrd der Konverter in üblicher Weise umgelegt, zum Blasen dann hochgestellt, so daß die Konvertermündung sich gegen das Verbindungsstück C legt. Die Abgase durchdringen das im DrehrohrB und Schacht A befindliche Erz und reduzieren es.For filling, the converter is turned over in the usual way, for blowing then raised so that the converter mouth is against the connector C lays. The exhaust gases penetrate the ore and located in the rotary kiln B and shaft A reduce it.

Soll das Erz in den Konverter gebracht werden, läßt man das Drehrohr sich drehen. Man hat es dann in der Hand, viel Erz weniger stark reduziert oder wenig Erz stark reduziert in den Konverter zu bringen. Je nachdem, wie man den Prozeß im Konverter führen will, wird man den einen oder den anderen Weg einschlagen.If the ore is to be brought into the converter, the rotary kiln is left turn around. You then have it in your hand, a lot of ore reduced or less Bringing little ore greatly reduced into the converter. Depending on how you get the process If you want to lead in the converter, you will take one path or the other.

Erster Fall: In dem Konverter befindet sich Roheisen mit hohem Phosphorgehalt. Klan will ein Produkt erzeugen, ähnlich dem Vormetall beim Roheisenerzvcrfahren, mit einem Kohlenstoffgehalt von etwa i 00 und möglichst geringem Phosphorgehalt.First case: The converter contains pig iron with a high phosphorus content. Clan will produce a product similar to the Vormetall when Roheisenerzvcrfahren, with a carbon content of about 00 i and the lowest possible phosphorus content.

Man gibt dann gleich beim Beginn des Blasens unter Zusatz von Brennstoffen stark oxydisches Erz und Kalk zu, um in bekannter Weise den Phosphor des Roheisens zu oxidieren und an die Schlacke zu binden. Durch Regelung der Erzmenge und des Verhältnisses zwischen Wind und Brennstoff wird außerdem das Bad auf den gewünschten Kohlensto.itgehalt gebracht.One then gives right at the beginning of the blowing with the addition of fuels strongly oxidic ore and lime to form the phosphorus of pig iron in a known manner to oxidize and bind to the slag. By regulating the amount of ore and the The ratio between wind and fuel will also set the bathroom to the desired one Carbon content brought.

Zweiter Fall: Durch den wie oben geführten Prozeß ist der Phosphor aus dein Roheisen entfernt, oder ein phosphorarmes Eisen ist in den Konverter eingebracht. Die Menge des Bades soll möglichst stark vermehrt werden durch Reduktion von Eisenerzen. Bei diesem Verfahren regelt man den Vorschub der Erze so, daß möglichst weitgehend reduziertes Erz in den Konverter gelangt, dort vom Bade aufgenommen und in ihm fertig reduziert wird.Second case: By the process as outlined above, the phosphorus is removed from your pig iron, or a low-phosphorus iron is introduced into the converter. The amount of the bath should be increased as much as possible by reducing iron ores. In this process, the feed rate of the ores is regulated so that as far as possible reduced ore gets into the converter, there absorbed by the bath and finished in it is reduced.
