Description

Verfahren zur Erhöhung der Lebensdauer von feuerfesten mit Kühlrohrvorsatz versehenen Zustellungen Zum Schutz von feuerfesten Zustellungen ist die Verwendung von Kühlrohren bekannt. Die Erfindung bezieht sich auf solche Anlagen dieser Art, bei deren die Kühlelemente vor den Wandungen der feuerfesten Zustellungen angeordnet sind und-bei denien die Beanspruchung der Kühlrohre sehr stark ist, da diese unmittelbar den zerstörenden Einüssen der Temperatur und der Schlacke ausgesetzt sind.Process to increase the service life of refractories with cooling tube attachment provided linings To protect fireproof linings, the use of known from cooling tubes. The invention relates to such systems of this type, in which the cooling elements are arranged in front of the walls of the refractory linings are and-in denien the stress on the cooling tubes is very strong, since these are immediate are exposed to the damaging effects of temperature and slag.

Die Steigerung der Lebensdauer sowohl der Kühlrohre als auch der hinter denselben liegenden feuerfesten Zustellung wird gemäß vorliegender Erfindung dadurch erreicht, daß durch eine aus. hochfeuerfestem Werkstoff- bestehende sogenannte Torkretschutzschicht die Kühlrohre miteinander verbunden werden.Increasing the service life of both the cooling tubes and the behind the same lying refractory lining is thereby made according to the present invention achieved that through one out. highly refractory material - existing so-called Torkret protection layer the cooling pipes are connected to one another.

Ein Ausführungsbeispiel des Erfindungsgedankens ist auf der Zeichnung dargestellt. Voi der zu schützenden Wandung a der feuerfesten Zustellung liegen die Kühlrohre b nebeneinander in gewissen Abständen c. Gemäß der Erfindung werden diese Rohre durch eine sogenannte Torkretschicht d aüs feuerfestem Staff miteinander verbunden, so daß vor der Wandung a eine zweite Wand gebildet wird, welche sich aus den Rohrele- . menten b und der Torkretschutzschioht d zusammensetzt, deren hochfeuerfeste Eigenschaften den jeweiligen Betriebsverhältnissen angepaßt sind. Um ein Abgleiten der feuerfesten Torkretschicht d von den Rohren b zu vermeiden und um Rücksicht auf die verschiedenen Ausdehnungskoeffizienten von Rohren und Torkretschicht zu nehmen, werden die Rohre vor dem Anbringen der Torkretsrhutzschicht mit einem feinmaschigen Drahtgewebe bespannt, welches sehr fest an den Rohrwandungen anliegt. Die Stärke der Torkretschicht beträgt im allgemeinen nur wenige Zentimeter.An embodiment of the inventive concept is shown in the drawing. Before the wall a of the refractory lining to be protected, the cooling tubes b lie next to one another at certain distances c. According to the invention, these pipes are connected to one another by a so-called Torkretschicht d aüs fireproof staff, so that a second wall is formed in front of the wall a, which is made up of the Rohrele-. elements b and the Torkretschutzschioht d composed, whose highly fire-resistant properties are adapted to the respective operating conditions. In order to prevent the fireproof Torkret layer d from sliding off the pipes b and to take account of the different coefficients of expansion of the pipes and Torkret layer, the pipes are covered with a fine-meshed wire mesh before the Torkretrhutzschicht is applied, which is very tight against the pipe walls. The thickness of the Torkret layer is generally only a few centimeters.

Durch Anwendung, des vorstehend gekennzeichneten Verfahrens ist es möglich, einen vollkommenen Schutz der feuerfesten Zustellur.gswandung a zu erreichen. Da das Verfahren leicht auszuführen und billig in seiner Anwendung ist, so ist damit ein erheblicher technischer Fortschritt erreicht.By applying the method identified above, it is possible to achieve complete protection of the fire-proof lining wall a. Since the method is easy to perform and inexpensive to use, so is it a considerable technical advance achieved.
