Abstract
Description
VERFAHREN ZUR BESEITIGUNG VON MAUERSENKUNGEN Die Erfindung betrifft ein Verfahren zur Beseitigung von Mauersenkungen im Brennraum eines Industrieofens, der seitlich von Mauern aus feuerfesten Ziegeln begrenzt ist, welche Mauern außen von einem Blechmantel oder Trägergerüst umgeben sind. Im Laufe der Zeit können sich diese Mauern nach innen neigen, besonders wenn einzelne der feuerfesten Ziegel oder der Mörtel beim Betrieb des Ofens beschädigt wurden. Dann genügte es bisher nicht, die schadhaften Stellen im Mauerwerk auszubessern, sondern es mußte die ganze Mauer abgerissen und lotrecht bzw. mit dem ursprünglichen steilen Winkelmaß neu errichtet werden. Diesen erheblichen zusätzlichen Reparaturaufwand zu vermeiden, ist Aufgabe des erfindungsgemäßen Verfahrens, welches darin besteht, daß ein gestufter, in Absenkungsrichtung sich erweitender Durchbruch in das Mauerwerk gestermmt und darin ein keramischer Wandanker eingemörtelt wird durch Eingießen oder Einstampfen oder Eins ritzen von feuerfester Messe, wobei der Anker über seine Klaue und ein Halteeisen mit einer S@annvorrichtung am Ofengerüst abgestützt und diese nach dem Aushärten der feuerfesten Masse im Aufrichtsinne betätigt wird. Durch mäßiges Anziehen und gelegentliches Nachstellen der Spannvorrichtung wird die wertvolle feuerfeste Mauer langsam und schonend in die urspüngliche Position zurückgebracht, bis zum Anliegen gegen den Blechmantel oder das Trägergerüst. Die Spannvorrichtung bleibt eingebaut und verhindert zuverlässig eine erneute Absenkbewegung der reparierten Mauer. Zum dauerhaften Schutz gegen die Hitzeeinwirkung werden vorteilhaft auch das etwa aus der Tand ragende rückwärtige Tnde des Ankers samt der darauf sitzende Klaue und dem in diese greifenden Ende des Halteeisens mit der feuerfesten Masse überzogen. METHODS FOR REMOVING WALL DROPPING The invention relates to a method for the removal of wall subsidence in the combustion chamber of an industrial furnace, which is bordered on the sides by walls made of refractory bricks, which walls are outside are surrounded by a sheet metal jacket or support frame. Over time can become these walls slope inward, especially when single of the refractory bricks or the mortar was damaged during the operation of the furnace. Then it was not enough until now to mend the damaged areas in the masonry, instead it had to cover the whole wall demolished and rebuilt vertically or with the original steep angle will. Avoiding this considerable additional repair effort is the task of the method according to the invention, which consists in that a stepped, in Lowering direction widening breakthrough cut into the masonry and into it a ceramic wall anchor is mortared by pouring in or ramming or One scratch from refractory mass, with the anchor over its claw and a holding iron supported with a S @ ann device on the furnace frame and this after hardening the refractory mass is actuated in the upright direction. By dressing moderately and Occasional readjustment of the tensioning device becomes the valuable refractory wall slowly and gently brought back to the original position, up to the issue against the sheet metal jacket or the support frame. The clamping device remains installed and reliably prevents the repaired wall from lowering again. To the Permanent protection against the effects of heat will also be beneficial about this the rear end of the anchor, together with the claw and the end of the holding iron gripping in this coated with the refractory mass.
In der Abbildung ist schematisch in Seitenansicht teilweise geschnitten, eine erfindungsgemäß reparierte Mauer dargestellt.In the figure is schematically partially cut in side view, a wall repaired according to the invention is shown.
Der teilweise gezeichnete Brennraum 10 des Industrieofens ist seitlich begrenzt von einer lotrechten Mauer 1, die 9a gegen den äußeren Mantel/ oder ein Trägergerüst 9 in ihre lotrechte Stellung zurückgezogen wurde durch Betätigung einer Spannschraube 7 am Offensgerüst, welche über das Halteeisen 5 und die Klaue 4 auf den bekannten keramischen Wandanker 3 wirkt, der in einen vorher in die Mauer 1 gestemmten gestufen und in Spannrichtung konvergierenden Durchbruch 2 eingemörtelt wurde mit feuerfester Masse 6.The partially drawn combustion chamber 10 of the industrial furnace is on the side bounded by a vertical wall 1, the 9a against the outer coat / or a Support frame 9 was withdrawn into its vertical position by actuating a Clamping screw 7 on the open frame, which over the retaining iron 5 and the claw 4 on the known ceramic wall anchor 3 acts, which in a previously in the wall 1 chiselled stepped and in the tensioning direction converging breakthrough 2 mortared was made with refractory mass 6.
