Description
Verfahren zur Herstellung von hochfeuerfesten Steinen Die Erfindung betrifft ein Verfahren zur Herstellung von hochfeuerfesten Steinen.Method of making high refractory bricks The invention relates to a process for the production of highly refractory bricks.
Feuerfeste Körper, Steine, Blöcke, Platten u. dgl. werden zum wesentlichen Teil aus einer körnigen Grundmasse, gegebenenfalls aus einer erkalteten Schmelze bereitet, hergestellt, welche mit einem Bindemittel vermischt, verformt und anschließend gebrannt «erden. Als Bindemittel findet in erster Linie Ton Verwendung, daneben auch Wasserglas oder organische Klebstoffe. Für einige Sonderfälle sind auch andersartige, als Bindestoff wirkende Massen in Vorschlag gebracht worden. So hat man auch Magnesia bzw. Chromerz als Bindestoff benutzt, und zwar zur Herstellung von Formkörpern mit Zirkonoxyd, Chromeisenstein, Cyanit, Bauxit und Quarzsteinen als Grundsubstanz.Refractory bodies, stones, blocks, plates and the like become essential Part made from a granular base material, possibly from a cooled melt prepares, manufactured, which mixed with a binder, deformed and then burnt «earth. Clay is primarily used as a binding agent, along with it also water glass or organic adhesives. For some special cases there are also different, masses acting as binders have been proposed. That's how you have magnesia or chrome ore used as a binding agent, specifically for the production of moldings with Zirconium oxide, chrome iron stone, cyanite, bauxite and quartz stones as the basic substance.
Gemäß der vorliegenden Erfindung wird Chromerz oder Magnesit oder beide Stoffe als Bindemittel benutzt, und zwar zur Herstellung hochfeuerfester Steine aus einer neuartigen und sich ganz besonders verhaltenden Grundsubstanz.According to the present invention, chrome ore or magnesite or Both substances are used as binders, namely for the production of highly refractory bricks from a new and particularly behaving basic substance.
Das neue Verfahren ist dadurch gekennzeichnet, daß aus Oxyden des Magnesiums, Chroms, Aluminiums und Siliciums diese Oxyde enthaltenden Mineralien u. dgl. durch Zusammenschmelzen bei hohen Temperaturen, und zwar in einem derartigen Verhältnis, daß sich die Verbindungen der genannten Oxyde bilden können, Massen erzeugt werden, welche nach dem Erkalten gekörnt und unter Zusatz von vorzugsweise fein gemahlenem Chromerz oder Magnesit oder beiden Stoffen und gegebenenfalls auch unter Zusatz organischer oder anorganischer Klebstoffe verformt werden, worauf die Formlinge gebrannt werden.The new process is characterized in that des oxides Minerals containing these oxides of magnesium, chromium, aluminum and silicon and the like by fusing them together at high temperatures in such a way Ratio that the compounds of the oxides mentioned can form, masses are produced, which after cooling are granulated and with the addition of preferably finely ground chrome ore or magnesite or both substances and possibly also be deformed with the addition of organic or inorganic adhesives, whereupon the Briquettes are fired.
Die erfindungsgemäß zu verformende Grundsubstanz wird durch Zusammenschmelzen entsprechender Oxyde in dem genannten Verhältnis hergestellt und besitzt Eigenschaften, durch welche sie sich für feuerfeste Zwecke, insbesondere dort, wo es sich um höchste Beanspruchungen bezüglich Temperaturen, Schlackenangriffe u. dgl. handelt, besonders eignet. Die besonderen vorzüglichen Eigenschaften der Grundsubstanz werden aber, wie vom Erfinder überraschenderweise erkannt, nur dann erhalten, wenn die Bindung ; der erkalteten gekörnten Masse durch Magnesit oder Chromerz oder beides erfolgt. Mit Ton oder anderen Stoffen sind nur relativ geringwertige Körper herzustellen.The basic substance to be deformed according to the invention is melted together corresponding oxides produced in the specified ratio and has properties, by which they are used for refractory purposes, especially where it is supreme Stresses with regard to temperatures, slag attacks and the like. Acts, in particular suitable. The special excellent properties of the basic substance are, however, as recognized by the inventor, surprisingly, only obtained when the bond ; the cooled granular mass is carried out by magnesite or chrome ore or both. Only relatively inferior bodies can be produced with clay or other substances.
Die neuartigen, als Grundsubstanz dienen- ; den Massen haben die Eigenschaft, bei hohen Temperaturen ganz besonders weitgehend von Oxyden bzw. Oxydgemischen durchsetzt zu werden. Diese Eigenschaft bewirkt es, .daß verhältnismäßig geringe Mengen freier Oxyde t zur völligen Durchdringung der Massen aus Oxydverbindungen genügen. Diese Eigenschaft wird erfindungsgemäß dadurch ausgenutzt, daß Chromeisenstein oder Magnesit oder beide Stoffe als Bindemittel vorzugsweise in fein gemahlenem Zustande verwendet «-erden. Dabei wird man sich bezüglich der Auswahl des Bindestoffes bzw. des Gemisches der Bindestoffe nach der Verwendung des zu erzeugenden Materials richten.The new ones, which serve as the basic substance; the masses have the property at high temperatures particularly largely interspersed with oxides or oxide mixtures to become. This property causes .that relatively small amounts of free Oxides t suffice for complete penetration of the masses of oxide compounds. These Property is used according to the invention in that chromium iron stone or magnesite or both substances are used as binders, preferably in a finely ground state "-earth. In doing so, you will be concerned with the selection of the binding agent or the mixture the Adjust binders according to the use of the material to be produced.
Da die Bindewirkung vorgenannter Stoffe im allgemeinen erst bei höheren Temperaturen wirksam wird, kann es erforderlich sein, für das Zusammenhalten der Steine vor dem Brennen auch anorganische oder organische Klebstoffe zuzusetzen. Hierzu sind besonders solche geeignet, welche beim Brennen der Steine mehr oder weniger verdampfen.Since the binding effect of the aforementioned substances generally only occurs with higher Temperatures will take effect, it may be necessary for the holding together of the Also add inorganic or organic adhesives to stones before firing. For this purpose, those are particularly suitable, which when burning the stones or more evaporate less.
Die Formgebung erfolgt in üblicher Weise durch Hand oder maschinell, und ebenso geschieht das Brennen in den für die Erzeugung feuerfesten Erzeugnisse üblichen Öfen.The shaping is done in the usual way by hand or by machine, and the same is true for firing in the refractory products used for making them usual ovens.
Die Erzeugnisse gemäß der Erfindung zeichnen sich durch außerordentlich hohe Feuerfestigkeit, durch einen sehr hohenDruckerweichungspunkt, daneben auch durch hervorragende Widerstandsfähigkeit gegen Schlackenangriffe aus.The products according to the invention are characterized by extraordinary high fire resistance, due to a very high pressure softening point, also due to its excellent resistance to slag attacks.
