Description

Die Erfindung betrifft eine Haltevorrichtung für monolithisch ausgekleidete Ofenwände, umfassend einen keramischen Ankerstein zur Verankerung einer monolithischen Auskleidung und ein Befestigungsmittel zur Befestigung des keramischen Ankersteins an einer Ofenwand.The invention relates to a holding device for monolithic lined furnace walls comprising a ceramic Anchor stone for anchoring a monolithic lining and a fastener for fastening the ceramic anchor stone on a furnace wall.

Aufgrund zunehmender thermischer und chemischer Belastungen in Kochtemperaturanlagen, wie z.B. in der Zementproduktion, sind den rein metallischen Verankerungen für monolithische Auskleidungen in den einzelnen Ofenbehältern stoffliche Grenzen gesetzt. Due to increasing thermal and chemical loads in cooking temperature systems, e.g. in cement production, are the purely metallic anchorages for monolithic Linings in the individual oven containers set material limits.

Aus diesem Grund ist der Einsatz sogenannter keramischer Anker mehr in den Vordergrund gerückt. Die Verwendung der keramischen Anker ist dabei von besonderem Interesse in Temperaturbereichen ab ca. 1.000 bis 1.200°C, jedoch kann eine Applikation bei Temperaturen unterhalb von 1.000°C aus technischer und wirtschaftlicher Sicht ebenfalls sinnvoll sein.For this reason, the use of so-called ceramic Anchor moved to the foreground. The use of the Ceramic anchor is of particular interest in Temperature ranges from approx. 1,000 to 1,200 ° C, however, can an application at temperatures below 1,000 ° C also makes sense from a technical and economic point of view his.

Bei den bisher bekannten keramischen Verankerungen ist der Ankerstein, der entweder als Handform oder als plastisch gefertigtes Format zur Verfügung steht, über eine Keilverbindung in das Befestigungsmittel eingebracht, so daß es durch instationäre sowie stationäre thermische Einflüsse zu Ausdehnungen kommen kann, die den Ankerstein reißen lassen oder eine Beschädigung der Haltevorrichtung hervorrufen können.In the previously known ceramic anchorages, the Anchor stone, either as a hand shape or as a plastic Manufactured format is available via a wedge connection introduced into the fastener so that it through transient and stationary thermal influences expansion can occur that tear the anchor stone leave or cause damage to the holding device can.

Außerdem ist bei den bis dato auf dem Markt befindlichen keramischen Verankerungen eine wirtschaftliche Anwendung aufgrund eines äußerst ungünstigen Preis/Leistungsverhältnisses in den meisten Fällen auf spezielle hochbelastete Ofenbereiche beschränkt geblieben.In addition, the ones on the market to date ceramic anchors an economical application due to an extremely unfavorable price / performance ratio in most cases on special highly stressed Oven areas remained limited.

Aus der US-A-2,527,063 ist ein Verfahren zur Herstellung von Feuerfeststeinen für aufgehängte Ofendecken bekannt, bei dem die Feuerfeststeine auf einer hydraulischen Presse mit einem metallischen Einsatz verpreßt werden, um eine feste Verbindung zwischen dem Feuerfeststein und dem metallischen Einsatz zu ermöglichen. Über den metallischen Einsatz ist der Feuerfeststein dann an eine Ofenwand befestigbar.From US-A-2,527,063 is a process for the production of refractory bricks for suspended Oven ceilings known, in which the refractory bricks on a hydraulic press A metallic insert can be pressed to create a firm connection between the refractory stone and to enable metallic use. About the metallic insert is the Refractory stone can then be attached to a furnace wall.

Die US 3,295,280 beschreibt eine Haltevorrichtung mit mindestens einem keramischen Ankerstein und einem Befestigungsmittel mit einer Feder in Form eines Federblechs.US 3,295,280 describes a holding device with at least one ceramic anchor stone and a fastener with a spring in the form of a spring plate.

In der US 2,021,610 ist eine gattungsgemäße Haltevorrichtung offenbart. Diese Haltevorrichtung umfaßt einen Ankerstein, der im allgemeinen einen frustokonischen Körper aufweist, an dessen schmalere Seite eine umlaufende Rille und eine umlaufende Schulter bereitgestellt sind, wobei in die Rille und über die Schulter eine metallische Haltevorrichtung plaziert werden kann, mit deren Hilfe der Ankerstein an eine Ofenwand befestigt werden kann.A holding device of the generic type is disclosed in US Pat. No. 2,021,610. This holding device comprises an anchor stone, which generally has a frustoconical body, a circumferential groove and a circumferential shoulder are provided on its narrower side are, a metallic holding device are placed in the groove and over the shoulder can be used to attach the anchor stone to a furnace wall.

Aufgabe der Erfindung ist es daher, eine Haltevorrichtung der eingangs genannten Art zu liefern, die gegenüber dem Stand der Technik in wirtschaftlicher und qualitativer Hinsicht verbessert und somit vielseitiger und großflächiger einsetzbar ist.The object of the invention is therefore a holding device to deliver of the type mentioned above, which compared to the State of the art in economic and qualitative Regarded improved and thus more versatile and larger can be used.

Diese Aufgabe wird durch eine gattungsgemäße Haltevorrichtung gelöst, die dadurch gekennzeichnet ist, daß der An-kerstein auf hydraulischen Hochdruckpressen gefertigt ist.This task is accomplished by a generic holding device solved, which is characterized in that the anchor stone is manufactured on hydraulic high-pressure presses.

Vorteilhafterweise erfüllt die Herstellung von keramischen Ankersteinen auf hydraulischen Hochdruckpressen einen hohen durchgehend homogenen Qualitätsanspruch, so daß sie im Vergleich zu marktüblichen, als Handform oder plastisch gefertigtes Format vorliegenden Ankersteinen ein deutlich höheres Qualitätsniveau an mechanischen und mineralogischen Eigenschaften aufweisen und zudem günstig in der Herstellung sind.The manufacture of ceramic advantageously fulfills Anchor stones on high pressure hydraulic presses a high consistently homogeneous quality standards, so that they Compared to the market, hand-made or plastic manufactured format present anchors clearly higher quality level of mechanical and mineralogical Have properties and also cheap in Manufacturing are.

Erfindungsgemäß ist auch vorgeschlagen, daß sich der Ankerstein in Richtung der Ofenwand konusartig verjüngt.According to the invention it is also proposed that the anchor stone tapers conically towards the furnace wall.

Ferner kann vorgesehen sein, daß der Ankerstein mit mindestens einer Nut und/oder Rille ausgestaltet ist.It can also be provided that the anchor stone with at least a groove and / or groove is configured.

Dabei schlägt die Erfindung vor, daß eine oder mehrere Nuten und/oder eine oder mehrere Rillen versetzt zueinander, umlaufend angeordnet sind.The invention proposes that one or more Grooves and / or one or more grooves offset from one another, are arranged all around.

Die Konuszität sowie die Nut- und/oder Federgestaltung, in Form der Nut(en) und/oder Rille(n), des Ankersteins bewirken, bereits jede für sich und gemeinsam verstärkt, eine stabile Einbindung des Ankersteins in die monolithische Auskleidung bei gleichzeitiger Berücksichtigung der Gasdichcheit. Dies wirkt sich insbesondere auf die Haltbarkeit der Auskleidung positiv aus.The conicity as well as the tongue and / or groove design, in Shape of the groove (s) and / or groove (s) of the anchor stone, already strengthened for themselves and together, one stable integration of the anchor stone into the monolithic Lining with simultaneous consideration of gas tightness. This affects in particular the durability the lining is positive.

Weiterhin schlägt die Erfindung vor, daß das Befestigungsmittel metallisch ist. Furthermore, the invention proposes that the fastener is metallic.

Ferner kann nach der Erfindung vorgesehen sein, daß das Befestigungsmittel eine Klaue umfaßt, die an den Ankerstein angreift.Furthermore, it can be provided according to the invention that Fastening means includes a claw attached to the anchor stone attacks.

Dabei ist zur Gewährleistung eines sicheren Halts bzw. einer stabilen Lage des Ankersteins durch das Befestigungsmittel bevorzugt, daß der Ankerstein in seinem Kopfbereich, benachbart zu der Ofenwand, zwei von der Klaue umgreifbare Schultern aufweist.It is to ensure a secure hold or one stable position of the anchor stone by the fastener prefers that the anchor stone in its head area, adjacent to the furnace wall, two by the claw has palpable shoulders.

Erfindungsgemäß kann auch vorgesehen sein, daß das Befestigungsmittel einen Bügel aufweist, der einerseits mit der Klaue und andererseits mit der Ofenwand verbunden ist.According to the invention it can also be provided that the fastening means has a bracket, on the one hand with the claw and on the other hand is connected to the furnace wall.

Eine erfindungsgemäße Weiterbildung ist dadurch gekennzeichnet, daß das Befestigungsmittel eine Feder, vorzugsweise in Form eines Federblechs, umfaßt.A further development according to the invention is characterized in that that the fastener is a spring, preferably in the form of a spring plate.

Dabei schlägt die Erfindung vor, daß die Feder den Ankerstein physisch kontaktiert.The invention proposes that the spring the anchor stone physically contacted.

Mittels der Feder bzw. des Federblechs erfährt der Ankerstein, in der Klaue, vorteilhafterweise eine flexible, "schwimmende" Lagerung, die zum einen eine stabile Halterung der monolithischen Auskleidung auf Zug und zum anderen eine freie Beweglichkeit des Ankersteins in dem Befestigungsmittei ermöglicht. Dies stellt eine signifikante Verbesserung gegenüber bereits auf dem Markt vorhandenen, unbeweglichen Haltevorrichtungen dar. Bei den herkömmlichen Systemen ist nämlich der einbautechnisch unbedingt erforderliche, auf Zug ausgelegte, Kraftschluß des Ankersteins durch Eintreiben von Holz- oder Kunststoffkeilen bewirkt, wobei aufgrund der Keilverbindungen durch sowohl instationäre als auch stationäre thermische Einflüsse, die zu ggf. anisotropen Ausdehnungen der Materialien und unkontrollierten Spannungen führen können, die Ankersteine reißen und/oder die Befestigungsmittel beschädigt werden können.The anchor stone is experienced by means of the spring or the spring plate, in the claw, advantageously a flexible, "floating" storage, on the one hand a stable bracket the monolithic lining on train and on the other free movement of the anchor stone in the fastening means allows. This represents a significant one Improvement over existing ones on the market immovable holding devices. In the conventional Systems is the installation technically essential required traction of the anchor stone designed for tension by driving in wooden or plastic wedges causes, due to the wedge connections by both transient as well as stationary thermal influences that possible anisotropic expansion of the materials and uncontrolled The anchor stones can cause tension tear and / or the fasteners are damaged can.

Ferner kann erfindungsgemäß vorgesehen sein, daß die Feder an den Bügel und/oder die Klaue angeschraubt ist.It can also be provided according to the invention that the spring is screwed to the bracket and / or the claw.

Die Verwendung einer handelsüblichen Sechskantschraube inklusive Sechskantmutter, die als reine Montagehilfen auch keine besonderen Ansprüchen bspw. hinsichtlich ihres Temperaturverhaltens erfüllen müssen, ist fertigungstechnisch und preislich günstig.The use of a standard hexagon screw included Hexagon nut, which also as a pure assembly aid no special requirements, for example with regard to their temperature behavior must meet, is manufacturing technology and inexpensive.

Bevorzugt ist erfindungsgemäß auch, daß mindestens ein elastischer Dichtring, vorzugsweise ein gummiartiger O-Ring, in der Schraubverbindung des Befestigungsmittels angeordnet ist.It is also preferred according to the invention that at least one elastic sealing ring, preferably a rubber-like O-ring, arranged in the screw connection of the fastener is.

Dabei können nach der Erfindung zwei elastische Dichtringe vorgesehen sein, einer zwischen dem Kopf einer Schraube und einer Seite des Befestigungsmittels und ein anderer zwischen der anderen Seite des Befestigungsmittels und einer Schraubenmutter.According to the invention, two elastic sealing rings can be used be provided, one between the head of a screw and one side of the fastener and another between the other side of the fastener and a nut.

Der flexible Einsatz des Ankersteins durch Verwendung der Feder wird noch durch die Wirkung des oder der elastischen Dichtringe in der Schraubverbindung verstärkt. Dabei ist besonders vorteilhaft, daß nicht nur der Ankerstein in dem Befestigungsmittel frei beweglich gelagert ist, sondern auch die Klaue und der Bügel zueinander flexibel gehalten werden können. Diese hohe Flexibilität ist besonders beim erstmaligen Aufheizen von Ofensystemen erforderlich, bei dem aufgrund des zunehmenden Temperaturgradienten unterschiedliche Wärmeausdehnungsspannungen im Decken- und/oder Seitenwandaufbau auftreten können. Obwohl unter Betriebsbedingungen elastischen Dichtringe meist verbrennen, bleibt die Beweglichkeit in der Schraubverbindung trotzdem gewahrt.The flexible use of the anchor stone by using the Feather is still elastic by the action of the or Sealing rings reinforced in the screw connection. It is particularly advantageous that not only the anchor stone in the Fasteners are freely movable, but the claw and the bracket are kept flexible with respect to each other can be. This high level of flexibility is particularly important when it comes to initial heating of furnace systems required at the different due to the increasing temperature gradient Thermal expansion stresses in the ceiling and / or Sidewall construction can occur. Although under operating conditions mostly burn elastic sealing rings, the mobility in the screw connection remains maintained.

Unter anderem zur Montageerleichterung schlägt die Erfindung ferner vor, daß der Ankerstein in seinem Kopfbereich eine Ausnehmung aufweist, die der bereichsweisen Aufnahme eines Schraubenkopfs oder einer Schraubenmutter der Schraubverbindung des Befestigungsmittels dient. The invention proposes, among other things, to make assembly easier furthermore that the anchor stone in his head area has a recess that the area-wise recording a screw head or a nut Screw connection of the fastener is used.

Vorteilhafterweise, insbesondere hinsichtlich der Haltbarkeit, kann die Klaue erfindungsgemäß aus hitzebeständigem, ferritischem oder aus austenitischem Flachmaterial, vorzugsweise Flachstahl, durch Umformen hergestellt sein.Advantageously, especially with regard to durability, According to the invention, the claw can be made of heat-resistant, ferritic or austenitic flat material, preferably Flat steel, be made by forming.

Ebenso kann der Bügel gemäß der Erfindung aus hitzebeständigem, ferritischem oder aus austenitischem Flachmaterial, vorzugsweise Flachstahl, durch Umformen hergestellt sein.Likewise, the bracket according to the invention made of heat-resistant, ferritic or austenitic flat material, preferably flat steel, be produced by forming.

Ferner ist bevorzugt, daß das Federblech aus Federstahl besteht.It is also preferred that the spring plate made of spring steel consists.

Auch kann vorgesehen sein, daß die Klaue mit einer Isoliermatte umwickelt ist.It can also be provided that the claw with an insulating mat is wrapped.

Schließlich ist erfindungsgemäß auch vorgeschlagen, daß zumindest ein Teil des Befestigungsmittels und ein Teil des Ankersteins mit einer Isolierwolle und/oder einer Isolierung, zwischen der Ofenwand und der monolithischen Auskleidung, umgeben ist.Finally, it is also proposed according to the invention that at least part of the fastener and part the anchor stone with an insulating wool and / or insulation, between the furnace wall and the monolithic lining, is surrounded.

Fig. 8 zeigt ein Befestigungsmittel zur Verwendung in einer erfindungsgemäßen Haltevorrichtung, das eine Klaue 70, einen Bügel 71, ein Federblech 72, eine Sechskantmutter 73, eine Sechskantschraube 74 und zwei O-Ringe 75, 75' umfaßt. Dabei sind die Klaue 70, der Bügel 71 und das Federblech 72 über die Sechskantschraube 74 unter Verwendung der Sechskantmutter 73 verschraubt.Fig. 8 shows a fastener for use in a Holding device according to the invention, the claw 70, a Bracket 71, a spring plate 72, a hex nut 73, one Includes hexagon screw 74 and two O-rings 75, 75 '. there are the claw 70, the bracket 71 and the spring plate 72 over the hex bolt 74 using the hex nut 73 screwed.

Mittels des Federblechs 72 erfährt ein Ankerstein bei der Montage in die Klaue 70 eine flexible Lagerung, d.h. er ist in dem Befestigungsmittel frei beweglich stabil gelagert, so daß bspw. bei dem Entstehen von unkontrollierten Spannungen aufgrund von ggf. anisotropen thermischen Ausdehnungen eine Verkeilung oder ein Zerreißen des Ankersteins verhindert wird. Unterstützt wird diese Wirkung auch durch die beiden O-Ringe 75, 75' in der Schraubverbindung, zwischen der Sechskantmutter 73 und der Klaue 70 einerseits und dem Federblech 72 sowie dem Kopf der Sechskantschraube 74 andererseits, die insbesondere die Klaue 70 flexibel zu dem Bügel 71 hält. By means of the spring plate 72, an anchor stone experiences at the Installation in the claw 70 flexible storage, i.e. he is freely movably and stably supported in the fastener, so that, for example, when uncontrolled tensions arise due to possibly anisotropic thermal expansion Wedging or tearing of the anchor stone prevented becomes. This effect is also supported by the two O-rings 75, 75 'in the screw connection, between the Hexagon nut 73 and the claw 70 on the one hand and the spring plate 72 and the head of the hexagon screw 74 on the other hand, which in particular the claw 70 flexible to the bracket 71 holds.

Die hohe Flexibilität aufgrund der Wirkung des Federblechs 72 sowie der O-Ringe 75, 75' ist vor allem beim erstmaligen Aufheizen von Ofensystemen, aufgrund der dabei häufig auftretenden Ausdehnungen im Seitenwand- und/oder Deckenaufbau, erforderlich. Unter Betriebsbedingungen verbrennen die O-Ringe 75, 75' zwar meist, aber die Beweglichkeit in der Schraubverbindung bleibt dennoch bewahrt. Daher liegt eine bewegliche Haltevorrichtung vor.The high flexibility due to the effect of the spring plate 72 and the O-rings 75, 75 'is especially the first time Heating of furnace systems, due to the frequently occurring ones Extensions in the side wall and / or ceiling structure, required. The O-rings burn under operating conditions 75, 75 'mostly, but the flexibility in the The screw connection is still preserved. Therefore there is one movable holding device in front.

Durch Nutzung von Fertigungssynergie, konstruktiver Innovation sowie materialwirtschaftlicher Disposition liefert die Erfindung somit großflächig sowie vielseitig einsatzbare Haltevorrichtigungen für monolithisch ausgekleidete Ofenwände.By using manufacturing synergy, constructive innovation and material planning Invention thus large and versatile Holding devices for monolithically lined furnace walls.
