Description

Anwendung einer Sintermasse zum Auskleiden von Rohren Bisher hatte die aus feuerfesten Steinen oder einer :entsprechenden Schutzmasse bestehende Auskleidung in Rohren für die Leitung heißer Abgase, insbesondere in Gasmaschinenauspuffleitungen, - nur geringe Lebensdauer. Durch die auf solche Rohrleitungen sich äußernden MaschinenQrschütterungen in Verbindung mit der Ilitzewirkung der Auspuffgase erlitt die Auskleidung, selbst bei einer besonderen Ärmierung, ähnlich wie beim Eisenbau, eine verhältnismäßig schnelle Zerstörung, deren Beseitigung infolge des Ausbauens und Wiederanbringens der neu gefütterten; Rohre :einen längeren Stillstand der Maschine erforderte. Besonders nachteilig trat dies bei Hochofengebläsemäschinen in die Erscheinung.Application of a sintered mass for lining pipes so far had the lining consisting of refractory bricks or a corresponding protective mass in pipes for the conduction of hot exhaust gases, especially in gas engine exhaust pipes, - only short service life. Due to the machine vibrations expressed on such pipelines in connection with the illicit effect of the exhaust gases, the lining suffered itself in the case of a special armouring, similar to iron construction, a proportionate one rapid destruction, their elimination as a result of dismantling and reinstallation the newly fed; Pipes: the machine had to be stopped for a long time. Particularly this was disadvantageous in the case of blast furnace blower machines.

Außer Massier keramischer- Art, vermischt mit pulverigen oder körnigen Metallegierungen oder -gemischen, aus denen geformte Gegenstände :einem allseitigen Brennprozeß unterworfen werden, ist :es auch bekannt, feuerfeste Tiegelmassen in gleicher Weist zu behandeln. Ferner hat man für Zementdrehöfen vorgeschlagen, das aus Schamottesteinen bestehende Innenfutter mit einemklink erartigen Schutzüberzug zu versehen, der jedoch das besondere Auftragen verschiedener Schichten anderer Stoffe notwendig machte.Except ceramic-type massagers, mixed with powdery or granular ones Metal alloys or mixtures that make up molded objects: an all-round Firing process is: it is also known to put in refractory crucible masses same way to treat. It has also been proposed for rotary cement ovens that Lining made of firebricks with a clinker-like protective cover to provide, however, the special application of different layers of others Made fabrics necessary.

Um den, Nachteilen bei genannten Rohrleitungen zu begegnen, findet gemäß der Erfindung zum Auskleiden von Rohren :eine aus verschiedenen Stoffen zusammengesetzte Masse Anwendung, die eist nach dem Einbringen in ein Rohr vorn innen her gebrannt wird und in dichtem Zusammenhalt verbleibt. Die Zusammensetzung der Masse ist derart, daß die Auskleidung durch das Brennen an der freien Oberfläche zum Verschlacken gebracht werden kann. Man hat dadurch eine innig zusammenhängende, glasierte, verhälteismäßig dünne Isolierschicht. Obwohl die Verschlackung so weit durchgeführt wird, daß sich die Auskleidung selbst trägt, bleibt es natürlich unbienommen, noch eine mit dem Außenrohr verbundene Armierung für die Auskleidung zu benutzen.In order to counteract the disadvantages of said pipelines according to the invention for lining pipes: one composed of different materials Mass application, which is fired after being introduced into a pipe at the front inside becomes and remains in close cohesion. The composition of the mass is such that the lining is slagging due to the burning on the free surface can be brought. Thereby one has an intimately coherent, glazed, relative quality thin insulating layer. Although the slagging is carried out so far that wears the lining itself, of course there is no action to take, another one with the Reinforcement connected to the outer pipe to be used for the lining.

Die zur Anwendung gelangende Masse besteht aus Steinmehl, beispielsweise Schamotte, Ton, Gußspänen, Asbestwolle und Natriumhydroxyd oder Kaliumhydroxyd. Die Zusammensetzung beträgt etwa 2o Gewichtsteile Schamottemehl, 30 Gewichtsteile Ton, 32 Gewichtsteile Gußeisen.späne, i Gewichtsteil Asbestwolle und i Gewichtsteil Natrium-oder Kaliumhydroxyd.The mass used consists of stone flour, for example fireclay, clay, cast chips, asbestos wool and sodium hydroxide or potassium hydroxide. The composition is about 20 parts by weight of firebrick flour, 30 parts by weight of clay, 32 parts by weight of cast iron chips, 1 part by weight of asbestos wool and 1 part by weight of sodium or potassium hydroxide.

Diese Stoffe werden mittels Wasser zu eurem Teig angerührt, in das Rohr in geeigneter Dicke :eingetragen und zunächst so an der Luft getrocknet. Die endgültige Trocknung erfolgt durch Beheizung vom Rohrinnern aus mit langsam ansteigender Temperatur, die schließlich bis zum Verschlacken der freien Futterschicht getrieben wird. Dabei bleibt die Auskleidung nach dem Rohr zu noch vollkommen porös; um einen Wärmeübergang nach außen möglichst zu verhindern. Die Gußeisenspäne erfüllen den Zweck seiner in jeder: Richtung verteilten Armierung, die bewirkt, daß die verschlackte Schicht der Auskleidung immer die gleiche Stärke behält, da die 'remperatur der durchströmenden Gase bei anfahrenden Gasmaschinen immer so hoch ist, daß die Masse nachsintert. Ein weiterer Vorteil besteht darin, daß die Auskleidungsmasse, abgesehen von ihrer Billigkeit, leicht und sicher eingebracht werden kann, gleichgültig, welche Form das Rohr hat.These substances are mixed into your dough with water, into the Pipe of suitable thickness: registered and initially air-dried. the Final drying takes place by heating from the inside of the pipe with a slowly increasing Temperature, which ultimately driven up to the slagging of the free lining layer will. The lining remains the pipe is still perfect porous; to prevent heat transfer to the outside as much as possible. The cast iron filings fulfill the purpose of its reinforcement, which is distributed in every direction, which causes that the slagged layer of the lining always retains the same thickness, since the temperature of the gases flowing through when gas engines are starting up is always so high is that the mass re-sintered. Another advantage is that the lining compound, apart from their cheapness, can be brought in easily and safely, indifferently, what shape the pipe is.
