Abstract
Description
Diese feuerfeste Ofenauskleidung umfaßt im wesentlichen eine aus einer Vielzahl nebeneinander und zueinander niveaugleich angeordneten Keramikfaser-lsolierstoff-Formteilen 1 zusammengefügte, die Offeninnenseite bildende, erste Schicht und eine aus feuerfesten, federelastisch nachgiebigen Fasermatten gebildete zweite Schicht 2. Letztere ist zwischen der ersten, aus Formteilen 1 zusammengefügten Schicht und der metallenen Ofenaußenwand 3 angeordnet. This refractory furnace lining essentially comprises one of a multitude next to each other and to each other arranged at the same level Ceramic fiber-insulating material molded parts 1 joined together, forming the open inside, first layer and one made of fire-resistant, resilient, flexible fiber mats formed second layer 2. The latter is between the first, made of molded parts 1 assembled Layer and the metal furnace outer wall 3 arranged.
Zwischen benachbarten, mit Abstand nebeneinander angeordneten Formteilen 1 ist jeweils eine T-förmig profilierte Leiste 4 angeordnet, wobei der Leisten-Steg 5 zwischen die Formteile 1 greift, während der Leistenflansch 6 ofeninnenseitig an den Formteilen 1 dichtschließend anliegt. Die Leisten 4 sind jeweils von mehreren, über deren Länge verteilt angeordneten, als Schrauben ausgebildeten Ankern 7 durchgriffen, mit welchen die Leisten 4 unter elastischer Vorspannung der zweiten Schicht 2 an die Ofenaußenwand 3 angespannt sind. Damit sind auch die Flansche 6 an die Formteile 1 dichtschließend angelegt. Between adjacent molded parts arranged at a distance from one another 1 a T-shaped profiled bar 4 is arranged in each case, the bar web 5 engages between the molded parts 1, while the bar flange 6 is on the inside of the oven rests tightly against the molded parts 1. The strips 4 are each of several, Anchors 7 designed as screws and arranged distributed over their length are penetrated, with which the strips 4 under elastic pretensioning of the second layer 2 the furnace outer wall 3 are strained. The flanges 6 are thus also attached to the molded parts 1 applied tightly.
Die Formteile 1 können zusätzlich noch über nicht dargestellte Anker mit der Ofenaußenwand 3 verbunden sein. The molded parts 1 can also have anchors, not shown be connected to the furnace outer wall 3.
In die Leisten 4 sind pro Anker jeweils ein glockenförmiges Widerlager 8 aus formfester Keramik eingeformt, wobei die Mündung des Widerlagers 8 dem Ofeninneren zugewandt ist. Durch den gelochten Boden eines jeden Ankerwiderlagers 8 ist der Schaft eines schraubenförmigen Ankers 7 so hindurchgeführt, daß sich deren Kopf innenseitig am Ankerwiderlager 8 axial abstützt. In the strips 4 there is a bell-shaped abutment per anchor 8 molded from dimensionally stable ceramic, with the mouth of the abutment 8 the furnace interior is facing. Through the perforated bottom of each anchor abutment 8 is the Shank of a helical armature 7 passed through so that its head axially supported on the inside on the armature abutment 8.
Der polygonale Kopf des Ankers 7 kann durch entsprechende Formgebung des Ankerwiderlagers 8 in letzterem auch verdrehsicher eingesetzt sein. The polygonal head of the armature 7 can be shaped accordingly of the armature abutment 8 can also be used in the latter so that it cannot rotate.
Der dem Kopf abgewandte Schaftendteil des Ankers 7 durchgreift eine diesem angepaßte Bohrung der Ofenaußenwand 3 und trägt eine an letzterer sich abstützende Schraubenmutter 9. The shaft end part of the armature 7 facing away from the head extends through a this adapted bore of the furnace outer wall 3 and carries a on the latter is supported Screw nut 9.
Das in Anspannrichtung sich etwa konisch verjüngendc Ankerwiderlager 8 reicht bis in den Steg 5 der Leiste 4 hinein, so daß das Widerlager 8 auf den Steg 5 der Leiste 4 auch radial gerichtete Vorspannkräfte ausübt. The armature abutment tapers conically in the tensioning direction 8 extends into the web 5 of the bar 4, so that the abutment 8 on the Web 5 of the bar 4 also exerts radially directed prestressing forces.
Um eine Überhitzung des Schraubenkopfes zu verhindern, kann in das glockenartige Ankerwiderlager 8 ein feuerfester, mindestens reibschlüssig gesicherter Stopfen 10 eingefügt werden. To prevent overheating of the screw head, the bell-like armature abutment 8 a fireproof, at least frictionally secured Plug 10 can be inserted.
Gemäß F i g. 2 sind die Formteile 1 aus Aluminium-Silicat-Faserstoffen, welche wie die Leisten 4 gemäß des in der deutschen Patentanmeldung P 32 13 951.9-16 offenbarten Verfahrens hergestellt sein können, randseitig so eingefast, daß benachbarte Formteile 1 gemeinsam jeweils eine zum Ofeninneren offene, rechteckig profilierte Nut 11 bilden, in die eine T-förmig profilierte Leiste 4 eingesetzt ist, wobei die dem Ofeninneren zugewandte Seite der Leiste 4 mit den dem Ofeninneren zugewandten Seiten der Formteile 1 bündig abschließen. According to FIG. 2 are the molded parts 1 made of aluminum silicate fibers, which like the strips 4 according to the in the German patent application P 32 13 951.9-16 disclosed method can be produced, beveled at the edge so that adjacent Molded parts 1 together each have a rectangular profile open to the furnace interior Form groove 11 into which a T-shaped profiled bar 4 is used, the the side of the bar 4 facing the interior of the oven with those facing the interior of the oven End the sides of the molded parts 1 flush.
Ferner sind hier zwischen der Leiste 4 und den Formteilen 1 feuerfeste Fasermatten 12 eingespannt. Die Länge der symmetrisch profilierten Leiste 4 entspricht mindestens der Kantenlänge der Formteile 1. In den Bereichen sich kreuzender Nuten 11 ist es vorteilhaft, wenn die Leisten 4 über die Formteile 1 hinausreichen und stirnseitig spiellos aneinanderliegen. Auch hier können zwischen den Stirnseiten der Leisten 4 feuerfeste Fasermatten 12 eingespannt sein. Furthermore, 1 are refractory between the bar 4 and the molded parts Fiber mats 12 clamped. The length of the symmetrically profiled bar 4 corresponds at least the edge length of the molded parts 1. In the areas of intersecting grooves 11, it is advantageous if the strips 4 extend beyond the molded parts 1 and lie against one another at the front without play. Here, too, can be between the end faces the strips 4 fireproof fiber mats 12 be clamped.
