Description

Hochfeuerfeste Kittmehle und daraus bereitete Mörtel, Stampf-, Flick- und Anstrichmassen ,Zur Herstellung hochfeuerfester Mörtel, Stampf- und Flickmassen werden in der Hauptsache Stoffe verwendet, die in ihren wesentlichen Eigenschaften den Grundstoffen der zu vermauernden feuerfesten Formkörper gleichen. Ebenso. werden zum Schutz von feuerfestem Mauerwerk vielfach feuerfeste Anstrichmittel verwendet, die aus den glei-.chen Stoffen wie die feuerfesten Steine bestehen oder die besonders hochwertige feuerfeste Stoffe, die sonst wegen ihres hohen Preises nicht als Vollkörper verwendet werden können, enthalten. Dabei werden die erwähnten feuerfesten Massen meistens mit Ton als Bindemittel zubereitet; zum Anmachen werden sie mit Wasser artgemischt und erhärten durch allmähliche Austrocknung, wie z. B. gewöhnlicher Schamottemörtel. Die Verwendung von selbsterhärtenden Massen für die genannten Zwecke, :etwa ,auf der Grundlage von Wasserglas ,als Bindemittel, ist nur bis zu einem gewissen Grade möglich, & durch den Zusatz von Alkalisilicat die Feuerbeständigkeit der Massenerheblich herabgesetzt wird.Highly refractory cement flour and mortar prepared from it, rammed, patch and paints, for the production of highly refractory mortars, ramming and patching compounds Mainly substances are used that have their essential properties resemble the basic materials of the refractory moldings to be bricked up. As well. will fire-resistant paints are often used to protect fire-resistant masonry, which consist of the same materials as the refractory bricks or which are special high quality fireproof fabrics, which because of their high price are otherwise not available as full bodies can be used. The refractory masses mentioned mostly prepared with clay as a binding agent; they can be turned on with water mixed species and harden by gradual dehydration, such as. B. more ordinary Fireclay mortar. The use of self-hardening compounds for the purposes mentioned, : about, on the basis of water glass, as a binder, is only up to a certain point Degrees possible & by the addition of alkali silicate the fire resistance of the The mass is significantly reduced.

Es wurde nun gefunden, daß @es bestimmte Stoffe von Spinellcharakter gibt, die mit Tonerdesolen, d. h. konzentrierten kolloidalen Lösungen von wasserlöslicher Tonerde angemacht, .selbsterhärtende-hochfeuerfeste Massen ;ergeben, die in ihrer praktischen Anwendung,die ,großen Vorteile eines selbsterhärtenden Materials ,auch für die hochfeuerfeste Bautechnik erlauben. Die Tonerdesolen werden in bekannter Weise aus Aluminiumchlorid durch Entfernung des Chlors hergestellt und können in beliebiger Konzentration, in dünn-und dickflüssiger Lösung, angewendet werden. Als spinellartige Verbindungen für die Herstellung von Kittmehlen u. dgl. gemäß der Erfindung kommt der vom alkalischen Aufschluß von Chromerzen anfallende Rückstand nach einer Glühbehandlung und ;anschließender Mählung in Betracht. Dieser Rückstand enthält in wechselnden Men genverhältnnissen Fee 03, Mg0, A12 08 und auch. noch Cr2 03.It has now been found that certain substances of spinel character are made with alumina sols, d. H. concentrated colloidal solutions of water-soluble Alumina mixed on, self-hardening, highly refractory masses, resulting in their practical application, the great advantages of a self-hardening material, too for the highly refractory construction technology. The clay sols are known in Way made from aluminum chloride by removing the chlorine and can be used in Any concentration, in thin and thick solution, can be used. as spinel-like compounds for the production of putty flours and the like according to FIG The invention comes from the residue from the alkaline digestion of chrome ores after an annealing treatment and; subsequent grinding into consideration. This residue contains Fee 03, Mg0, A12 08 and also in varying proportions. still Cr2 03.

Die auf diese Weise hergestellten Massen sind geeignet als selbsterhärtende hochfeuerfeste Mörtel wie auch für selbsterhärtende Stampf-, Flick-, Anstrich- und überzugmassen. Die Eigenschaft des Selbsterhärtens wird dadurch erreicht und beeinfl.ußt, daß man den oben beschriebenen Rückstand vom alkalischen Aufschluß der Chromerze, Ader gewöhnlich in fein pulverigem Zustand vorliegt, zunächst nach dem Trocknen zu einer klinkerartigen Masse brennt und dann den .erhaltenen Klinker mahlt. -- je nach der Mahlfeinheit bindet die fertige Mischung mit dem Tonerdesol mehr oder weniger rasch ab. Durch das Brennen :erreicht man einerseits eine genügend stärke Vörversinterung und andererseits -eine genügende Reaktionsfähigkeit des Produktes mit der wasserlöslichen Tonerde.The masses produced in this way are suitable as self-hardening highly refractory mortars as well as self-hardening rammed, patch, paint and coating masses. The property of self-hardening is achieved and influenced by that the residue described above from the alkaline digestion of the chrome ore, Usually in a fine powdery state, initially after drying burns to a clinker-like mass and then grinds the clinker obtained. - Depending on the grinding fineness, the finished mixture binds more or more with the alumina sol less quickly. By burning: on the one hand, you achieve sufficient strength Pre-sintering and, on the other hand, sufficient reactivity of the product with the water-soluble clay.

Die erwähnten, mit dem Chromerzrückstand hergestellten Mörtel, Stampf- und Anstrichmassen usw. zeichnen sich durch eine besonders gute Wärmeleitfähigkeit und Temperaturwechselbeständigkeit aus. Da sie ,die Eigenschaft -haben, von selbst zu erhärten, können aus ihnen auch Formkörper der verschiedensten Art hergestellt werden, die den besonderen Vorzug aufweisen, ohne vorheriges Brennen. lagerbeständig zu sein und für die feuerfeste Bautechnik verwendet wenden zu können.The above-mentioned mortars made with the chrome ore residue, rammed and paints, etc. are characterized by particularly good thermal conductivity and thermal shock resistance. Since they, have the property, by themselves to harden, molded bodies of various types can also be produced from them which have the special advantage of being without prior firing. shelf-stable to be and to be able to be used for refractory construction technology.

Der Rückstand vom alkalischen Chromerzaufschluß in dem Mörtelmehl kann teilweise durch andere Stoffe ersetzt sein, sofern diese in der fertigen Masse nicht die thermischen Eigenschaften unerwünscht beeinflussen; z. B. können andere feuerfeste Stoffe, -etwa Magerungsmittel, sowie auch Bindemittel, Flußmittel der verschiedensten Art u. dgl. beigemengt werden. Beispiel Der Rückstand vom alkalischen Aufschluß von Chromerzen wird auf iq.oo°C vorgeglüht und nach dem Erkalten gemahlen. Dias gemahlene Produkt wird abgesiebt. Aus den abgesiebten Kornfraktionen wird ein Kittmehl folgender Zusammensetzung zusammengestellt: 4.o % Durchgang durch ein Maschensieb von 5öo Maschen/qcm, Rückstand auf einem Maschensieb von goo Maschen/qcm; -5o % Durchgang durch ein Maschensieb von 23 i ö Maschen/qcm, Rückstand auf einem Maschensieb von 36oo Mas.chen/qcm; i o % Durchgang durch ein Maschensieb von io ooo Maschen/qcm.The residue from the alkaline chrome ore digestion in the mortar flour can be partially replaced by other substances, provided that these are in the finished mass do not affect the thermal properties undesirably; z. B. can others Refractory materials, such as lean agents, as well as binders, fluxes of various kinds and the like. Example The residue from the alkaline Digestion of chrome ores is pre-calcined to 100 ° C and ground after cooling. The ground product is sieved off. The sieved grain fractions become a Putty flour composed of the following composition: 4.o% passage through a mesh sieve of 50 meshes / qcm, residue on a mesh screen of goo meshes / qcm; -5o% Passage through a mesh screen of 23 10 meshes / square cm, residue on a mesh screen from 3,600 meshes / square centimeter; i o% passage through a mesh screen of io ooo stitches / qcm.

Von diesem Kittmehl werden ioo g mit 35 ccm Tonerdesol vom sp.ez. Gewicht r,4.5 angemacht. Die Masse .erhärtet nach kurzer Zeit und hat nach drei Tagen eine Festigkeit von durchschnittlich 5okg pro qcm. Probekörper aus der Masse werden von Wasser wie auch von Alkalilauge in der Kälte wie in der Siedehitze nicht angegriffen.100 g of this putty flour are mixed with 35 ccm of alumina sol from sp.ez. Weight r, 4.5 turned on. The mass hardens after a short time and has after three Days a firmness of an average of 5okg per square centimeter. Test specimen from the mass are not affected by water or alkali lye in the cold and in the boiling point attacked.

Die erhärteten Massen zeigen eine Feuerfestigkeit von über SK 38 (entsprechend über 185o°C) und eine Druckerweichung von 1320'C (tä) bei 2 kg Belastung.The hardened masses show a fire resistance of over SK 38 (corresponding to over 185 ° C) and a pressure softening of 1320 ° C (daily) with a load of 2 kg.

Die - groben Fraktionen des Mörtelmehls können durch feuerfeste Magerungsmittel von gleicher Körnung ersetzt sein; die Eigenschaft der hydraulischen Erhärtung wird vorzugsweise durch die feinsten Fraktionen der spinellartigen Verbindung bewirkt. Es können. ferner Flußmittel und bekannte Bindemittel irgendwelcher Art zugemischt werden.The - coarse fractions of the mortar flour can through refractory lean agents be replaced by the same grain; the property of hydraulic hardening becomes preferably effected by the finest fractions of the spinel-like compound. It can. furthermore, flux and known binders of any kind are mixed in will.
