Abstract

The hydrocarbon is selected from methane, ethane, propane, butane and oils e.g. such as fuel oil, kerosine, hexane, heptane and octane and their derivatives. They may be used in a carrier gas and the lining is pref. a binder-free or low binder-content refractory.

Description

"Verfahren zur Erhöhung der Haltbarkeit des feuerfesten Mauerwerks metallurgischer Gefäße" (Zusatz zu Patentanmeldung P 23 11 306.6) Die Erfindung bezieht sich auf ein Verfahren zur Erhöhung der Haltbarkeit des feuerfesten Mauerwerks von Öfen und metallurgischen Gefäßen durch Einlagerung von Kohlenstoff, bei dem ein fluider Kohlenstoffträger in situ in das Mauerwerk infiltriert wird, nach Patentanmeldung P 23 II 306.6."Method of increasing the durability of the refractory masonry metallurgical vessels "(addition to patent application P 23 11 306.6) The invention refers to a method of increasing the durability of the refractory masonry of furnaces and metallurgical vessels through the inclusion of carbon, in which a fluid carbon carrier is infiltrated in situ into the masonry, according to patent application P 23 II 306.6.

Das Verfahren nach der Hauptanmeldung ist darauf gerichtet, bei metallurgischen Gefäßen und Öfen während des laufenden Betriebes, also nicht nur während der Stillstandzeiten, Kohlenstoff in den Poren und Hohlräumen des feuerfesten Mauerwerks, insbesondere im Bereich der oberflächennahen entkohlten Zone einzulagern. Dies geschieht vorzugsweise durch Infiltration gasförmiger oder flüssiger Kohlenwasserstoffe.The process according to the main application is aimed at metallurgical Vessels and ovens during operation, i.e. not only during downtimes, Carbon in the pores and cavities of refractory masonry, in particular to be stored in the area of the near-surface decarburized zone. This is preferably done by infiltration of gaseous or liquid hydrocarbons.

Weitere Versuche haben nun gezeigt, daß sich einige Kohlenwasserstoffe in besonderem Maße für die Infiltration nach dem Verfahren der Hauptanmeldung eignen. Dies sind Methan, Äthan, Propan, Butan und Öl wie Heizöl, Kerosin, Hexan, Heptan und Oktan oder deren Abkömmlinge.Further experiments have now shown that some hydrocarbons particularly suitable for infiltration according to the procedure of the main application. These are methane, ethane, propane, butane and oil such as heating oil, kerosene, hexane, heptane and octane or their derivatives.

Die vorerwähnten Kohlenwasserstoffe können einzeln oder nebeneinander sowie in einem Trägermedium, beispielsweise einem Trägergas infiltriert werden.The aforementioned hydrocarbons can be used individually or side by side as well as be infiltrated in a carrier medium, for example a carrier gas.

Das Verfahren nach der Hauptanmeldung kann im übrigen auch so durchgeführt werden, daß der fluide Kohlenstoffträger dazu dient, die Bindung der feuerfesten Bestandteile einer Ausmauerung erst herbeizuführen oder zu verbessern. So kann beispielsweise eine Ausmauerung ohne Bindemittel oder mit einer geringen Menge eines Bindemittels hergestellt werden, die den Aufbau der Ausmauerung bzw. die Handhabung von Steinen für eine Ausmauerung erlaubt. Sobald die Ausmauerung dann fertiggestellt ist, kann ein Kohlenstoffträger infiltriert werden.The procedure according to the main application can also be carried out in this way be that the fluid carbon carrier is used to bind the refractory To bring about or improve the components of a brick lining first. For example a brick lining without a binder or with a small amount of a binder are made, the building of the masonry or the handling of stones Allowed for a brick lining. As soon as the brick lining is finished, you can a carbon carrier can be infiltrated.
