Description

Die Erfindung betrifft die Ausbildung der Blockkippkante an Wärmöfen. Der Erfindung liegt die Aufgabe zugrunde, ein Abtragen. des feuerfesten Materials des Herdes an der Kippkante westgehend zu verhindern.The invention relates to the formation of the block tilting edge on heating furnaces. The invention is based on the object of an ablation. of the refractory material to prevent the stove from going westward at the tilting edge.

Es ist eine Ausbildung der Kippkante bekannt, an welcher die Blöcke von der Herdsohle auf eine geneigte Fläche übergeben werden sollen, damit diese nach außen abrutschen'-können, bestehend aus zwei in Ofenlängsrichtung verlaufenden Rohren, auf denen die Blöcke gleiten--und' die entsprechend der Schrägfläche nach unten hin abgebogen, sind, wobeti die Scheitel der Rohre etwas über die Höhe der Herdsohle herausragen.It is known a design of the tilting edge on which the blocks should be transferred from the hearth to a sloping surface so that this can slip outwards, consisting of two running in the longitudinal direction of the furnace Pipes on which the blocks slide - and which follow the sloping surface bent downwards, the vertices of the tubes are slightly above the height of the The hearth stick out.

Diese Einrichtung ist seit langer Zeit bekannt und auch -in der Praxis benutzt worden, jedoch hat sich .herausgestellt, daß das feuerfeste Mauerwerk an der Herdkante- am Übergang zwischen dem waagerechten Teil der Sohle und- der Schrägfläche durchaus nicht in, dem gewünschten Maße geschützt ist. Das Mauerwerk wird nämlich zwischen den parallel verlaufenden Rohren im Laufe der Zeit an der Kippkante immer stärker abgetragen, da sich das feuerfeste Material des Herdes durch die Zundew- bzw. Schlackenablagerung mit herausschiebt.This facility has been known for a long time and is also in practice has been used, but it has been found that the fire-resistant masonry is on the hearth edge - at the transition between the horizontal part of the sole and - the inclined surface is by no means protected to the extent desired. The masonry will namely between the parallel pipes over time at the tilting edge more wear and tear, as the refractory material of the stove through the Zundew or slag deposits with pushes out.

Es ist weiterhin eine Ausbildung bekannt, bei welcher an der Kippkante ein quer zur Vorschubrichtung der Blöcke liegendes Rohr angeordnet ist, dessen Scheitel selbst die Kippkante bildet. Auch diese Einrichtung hat Nachteile, wenn sie auch bezüglich des Schutzes des Mauerwerkes gegen Abtragen günstiger ist als die zuerst beschriebene Einrichtung. Der. sehr wesentliche Nachteil besteht darin, daß der Block längs auf dem Rohr aufliegt und durch die Kühlung des Rohres einseitig sehr stark abgekühlt wird; was späterhin beim Walzen des Blockes zu erheblichen Schwierigkeiten führt. Nach dem Vorschlag der Erfindung werden die Knierohre in Längsrichtung des Ofens angeordnet, und zusätzlich wird in der Kehle der Knierohre ein quer liegendes Rohr vorgesehen. Hierdurch ist ein eihwandfrener Schutz der Kippkante- im Rahmen des überhaupt möglichen gewährleistet. Das in der Kehle der Knierohre liegende Querrohr kommt nicht unmittelbar mit den Blöcken in Berührung, es kann also, da der Block nur mit schmalen Zonen auf den Knierohren aufruht, eine die spätere Walzung ungünstig beeinflussende Abkühlung nicht eintreten., andererseits wird aber die Austragung des Herdmaterials zwischen den Knierohren duich das quer .liegende Rohr als Staurohr weitgehend verhindert.There is also a known training in which on the tilting edge a tube lying transversely to the direction of advance of the blocks is arranged, its apex itself forms the tilting edge. This setup also has drawbacks, albeit with them with regard to the protection of the masonry against erosion is more favorable than the first described facility. Of the. very significant disadvantage is that the Block rests lengthways on the pipe and very one-sided due to the cooling of the pipe is strongly cooled; which later led to considerable difficulties when rolling the block leads. According to the proposal of the invention, the knee tubes are in the longitudinal direction of the In the furnace, and in addition, a transverse tube is placed in the throat of the knee tube Tube provided. As a result, protection of the tilting edge is free from the wall of what is possible at all. The cross tube lying in the throat of the knee tube does not come into direct contact with the blocks, so it can be because the block only rests on the knee tubes with narrow zones, which is unfavorable for the later rolling influencing cooling does not occur, on the other hand, however, the discharge of the hearth material between the knee tubes you use the transverse tube as a pitot tube largely prevented.

Zur Erläuterung der Erfindung ist in den Abb. i und z schematisch im Längsschnitt und in Draufsicht auf den Herd die Austragungsseite eines Blockwärmofens dargestellt.To explain the invention is in Figs. I and z schematically in longitudinal section and in plan view of the hearth, the discharge side of a block heating furnace shown.

An dem Herd sind in Ofenlängsrichtung parallel zueinander drei Knierohre i mit Bewehrung z angeordnet. In der Kniekehle dieser Rohre i verläuft das Staurohr 3. Alle Rohre sind wassergekühlt.On the stove there are three knee tubes parallel to each other in the longitudinal direction of the oven i arranged with reinforcement z. The pitot tube runs in the hollow of the knee of this tube i 3. All pipes are water-cooled.
