Description

Wölber für feuerfeste Zustellung von zylindrischen Gefäßen und Ofen Die vorliegende Erfindung betrifft einen Wölber für feuerfeste Zustellungen von zylindrischen Gefäßen und Ofen.Vaults for refractory lining of cylindrical vessels and ovens The present invention relates to a vault for refractory linings of cylindrical vessels and furnace.

Für feuerfeste Zustellungen von Drehöfen, Schachtöfen, Roheisenmischern, Konvertern und dergleichen benutzt man Wölber aus keramisch- und/oder teergebundenen Massen, die z.B. bei Konvertern als Dauerfutter eingesetzt werden können. Die Wölber werden dabei so eingebaut, daß die Mantelseite des Wölbers mit der gesamten Fläche unmittelbar an dem Gefäßmantel zur Anlage kommt.For refractory lining of rotary kilns, shaft furnaces, pig iron mixers, Converters and the like are used vaults made of ceramic and / or tar-bound Masses that can be used as permanent feed in converters, for example. The arches are installed in such a way that the shell side of the arch with the entire surface comes to bear directly on the vessel jacket.

Hierdurch ist ein guter aber nicht erwunschter Wärmeübergang zwischen Zustellung und Gebfsßmantel gegeben und zwar insofern unerwünscht, da durch ständig hobe Temperaturen das Material des Gefäßmantels erlnüdet und dadurch das Stahlblechgefäß des Konverters oder der Blechmantel eines Drehrohrofens früher ersetzt werden muß als es bei niedrigen Temperaturen notwendig gewesen wäre.This results in a good but undesirable heat transfer between Delivery and Gebfsßmantel given and that is undesirable because by constantly High temperatures wear out the material of the vessel jacket and thereby the sheet steel vessel of the converter or the sheet metal jacket of a rotary kiln must be replaced earlier than would have been necessary at low temperatures.

Man hat schon versucht diesem Übe]. stand dadurch zu begegnen, daß man z0B. bei Konvertern den gesamten Gefäßmantel von aussen kühlt. Diese Maßnahme bedeutet aber einen verhältnismäßig hohen zusätzlichen Aufwand.One has already tried this exercise]. stood by to meet that one z0B. in the case of converters, cools the entire vessel jacket from the outside. This measure but means a relatively high additional effort.

Gemäß vorliegender Erfindung wird daher vorgeschlagen, daß der Wölber mantelseitig eine oder mehrere Ausnehmungen und/oder Erhöhungen aufweist.According to the present invention it is therefore proposed that the arch has one or more recesses and / or elevations on the shell side.

Durch diese Maßnahme liegen beispielsweise die Wölber bei Konvertern nicht mehr mit ihrer gesamten Mantelseite an der Gefäßwand an, sondern durch die Ausnehmungen und/oder Brhöhungen werden zwischen Wölber und Gefäßmantel Lufträume gebildet, die für den Gefäßmantel eine Isolierung bewirken. Die Manteltemperatur und Abstrahlverluste werden dadurch vermindert, wodurch zwangsläufig eine erhöhte Wärmespeicherung auftritt. So wird nicht nur die Haltbarkeit Zylindrischer Gefäße z.B. von Konvertern erhöht, sondern durch die erhöhte Wärmespeicherung wird audi ein grererer S hrotteinsatz möglich. Steine in derartiger Ausbildung können selbstverständlich auch in Öfen Verwendung finden wo auf Seden Fall Manteltemperatur und Abstrahlverluste vermindert werden.As a result of this measure, for example, the arches are located near converters no longer with its entire shell side on the vessel wall, but through the Recesses and / or elevations become air spaces between the vault and the vessel jacket formed, which cause insulation for the vessel jacket. The jacket temperature and radiation losses are thereby reduced, which inevitably increases Heat storage occurs. This not only increases the durability of cylindrical vessels e.g. increased by converters, but due to the increased heat storage, audi a larger amount of fuel is possible. Stones in such a training can of course They are also used in ovens, where in every case the jacket temperature and radiation losses be reduced.

Zur Verdeutlichung der vorliegenden Erfindung ist in der Zeichnung ein Wölber gemäß derErfindung wiedergegeben.To illustrate the present invention is in the drawing a bulge according to the invention is shown.

In der perspektivischen Darstellung eines wölbers erkennt man auf der Mantel seite Ausnehmungen, von denen eine durch x besonders bezeichnet und in vergrößertem Maßstab und als Ausschnitt nochmals wiedergegeben ist.In the perspective representation of a vault one recognizes the shell side recesses of which one by x especially labeled and reproduced again on an enlarged scale and as a detail is.
