Description

Verfahren zum Anheizen einer Verkokungsofenbatterie mit aus Silikasteinen aufgebautem Oberteil und n-üt aus Schamottematerial bestehender Ofendecke Bei bekannten Verfahren zum Anheizen einer Koksofenbatterie mit aus Silikasteinen aufgebautem Oberteil und mit aus Schamottematerial bestehender Ofendecke versuchte man die Undichtigkeiten in der Schamotteofendecke, die sich durch die stärkere-Ausdehnung des Silikaoberteils gegenüber der Schamotteofendecke ergeben, die zum Aufreißen der Ofendecke an ihrer Unterseite führt, durch Vergießen der Ofendecke mit Mörtel zu schließen.Method for heating a coking furnace battery with silica stones built-up upper part and n-üt made of fireclay material existing furnace ceiling with known Method for heating a coke oven battery with a built-up of silica stones The leaks were attempted at the top and with the oven ceiling made of firebrick material in the fireclay oven ceiling, which is due to the greater expansion of the silica top compared to the fireclay oven ceiling, which to tear open the oven ceiling on their Bottom leads to close by potting the furnace ceiling with mortar.

Es zeigte sich aber, daß durch Vergießen der Ofendecke mit Mörtel die Undichtigkeiten nicht beseitigt werden können, da die Risse von oben nicht erfaßt werden.It turned out, however, that by pouring the furnace roof with mortar the leaks cannot be eliminated because the cracks cannot be detected from above will.

Es ist weiter bekannt, der durch die Verschiedenartigkeit der beim Koksofenbau verwendeten Materialien bedingten verschieden starken Ausdehnung durch Hilfs-zuganker entgegenzuwirken und diese an solchen Stellen anzuordnen, an denen Rißbildung zu erwarten ist.It is further known that due to the diversity of the at The materials used in the construction of coke ovens caused different degrees of expansion To counteract auxiliary tie rods and to arrange them in those places where Cracking is to be expected.

Ebenso bekannt ist es, diese Hilfszuganker nach Erreichen einer örtlichen Aufheiztemperatur von 400 bis 500' C wieder zu entfernen.It is also known to remove these auxiliary tie rods again after a local heating temperature of 400 to 500 ° C. has been reached.

'trotz Anordnung von Hilfszugankern sind in der bei Erwärmung weniger stark wachsenden Schamotteofendecke Risse nicht ganz zu vermeiden.'Despite the arrangement of auxiliary tie rods, there are fewer when heated strongly growing fireclay oven ceiling cracks cannot be avoided entirely.

Die Erfindung sieht vor, die nach Entfernen der Hilfszuganker aus der während des Anheizvorganges bis auf 400 bis 500' C erhitzten Ofendecke in der Ofendecke frei gewordenen, zur Aufnahme der Hilfszuganker dienenden röhrenförmigen Löcher durch Einspritzen von feuerfestem Material zu füllen. Dadurch wird der bedeutende Vorteil erzielt, daß die trotz der Verspannung mittels der Hilfszuganker in der Ofendecke aufgetretenen Risse auf ganzer Länge der Kanäle und deren Umgebung, also auch an Stellen, die ohne solche durchgehenden öffnungen gar nicht mehr zugänglich sind, abgedichtet werden.The invention provides that after removing the auxiliary tie rods from the furnace ceiling, which was heated to 400 to 500 ° C during the heating process, the tubular holes for receiving the auxiliary tie rods are filled by injecting refractory material. This has the significant advantage that the cracks that appear in the furnace ceiling despite the tensioning by means of the auxiliary tie rods are sealed over the entire length of the ducts and their surroundings, i.e. also in places that are no longer accessible without such through openings.
