PATENTAMT.PATENT OFFICE.
Die nachstehend beschriebene Erfindung bezieht sich auf eine besondere Herstellung höchst feuerfester Steine aus gebranntem Magnesit, wie sie in den verschiedensten Industriezweigen zum Ausfüttern der Oefen, für Feuerbrücken u. s. w. erforderlich sind, und' besteht · in der Verwendung von Mischungen aus.gebranntem Magnesit, Hochofenschlackenmehl oder Thomasmehl und Chlornatrium. Die bisher von anderer Seite in den Handel gebrachten Steine haben sich nicht für jeden Zweck verwendbar erwiesen. Das beste Material zur Erzeugung von höchst feuerfesten. Steinen ist der in höchster Weifsglut gebrannte Magnesit, welcher bei dieser Hitze seinen Gehalt an C O2 vollständig verliert.The invention described below relates to a special production of highly refractory bricks from burnt magnesite, as are required in the most diverse branches of industry for lining the furnaces, for fire bridges, etc. Thomas flour and sodium chloride. The stones that have hitherto been brought onto the market from other sources have not proven to be suitable for every purpose. The best material for producing highly refractory. Stones is baked in the highest Weifsglut magnesite, which completely loses in this heat to its content of C O 2.
Dieses so gewonnene Fabrikat ist aber nicht bindefähig. Um nun einen Zusammenhalt dieser schwer zusammenfügbaren Masse im Feuer zu bewirken, hat Erfinder diesen" einmal gebrannten Magnesit unter Zusatz von Hochofenschlackenmehl oder Thomasmehl und Chlornatrium noch ein zweites Mal gebrannt, zuvor aber die gewonnenen Steine stark geprefst. Das Gewichtsverhältnifs ist 95 pCt. gebrannter Magnesit, 4 pCt. Hochofen- bezw. Thomasmehl und ι pCt. Chlornatrium. Je nach der beab-. sichtigten Verwendungsweise lassen sich die Procente an Eisenzusatz bis auf ο pCt. herabsetzen und dementsprechend an Chlornatrium erhöhen. Die mechanische Festigkeit und Feuerbeständigkeit dieser Mauersteine ist eine bisher auch nicht annähernd erreichte.However, this product obtained in this way cannot be bound. To cohesion now To bring about this difficult to assemble mass in the fire, inventor has this "once." Burnt magnesite with the addition of blast furnace slag meal or Thomas meal and sodium chloride Fired a second time, but the stones that were extracted were strongly pressed beforehand. The weight ratio is 95 pct. burned Magnesite, 4 pct. Blast furnace or Thomas flour and ι pCt. Sodium chloride. Depending on the intended. Depending on the way of use, the percentage of added iron can be reduced to ο pCt. reduce and increase accordingly in sodium chloride. The mechanical strength and fire resistance of these bricks is one not even remotely reached so far.
Die vielseitige Verwendung der Magnesitmauersteine in den verschiedensten-Fabriken, welche sehr hohe Hitzegrade beanspruchen, und die directe Berührung der betreffenden Fabrikate mit den Magnesitmauersteinen gestatten an Stelle des Magnesits auch die Verwendung des Magnesitübergangsgesteines, das in seiner Hauptsache eine asbestartige Zusammensetzung (also Magnesia, Eisenoxydul und Kieselsäure in sehr verschiedenen Procentsätzen) zeigt.The versatile use of magnesite bricks in various factories, which require very high degrees of heat, and the direct contact with them Manufactures with the magnesite bricks allow the use of magnesite instead of the magnesite transition rock, which is mainly an asbestos-like composition (i.e. magnesia, iron oxide and silica in very different percentages) shows.
Dieses Uebergangsgestein, wenn auch von viel weniger Kohlensäuregehalt als Magnesit, wird ebenfalls einmal gebrannt, pulverisirt, durch Zusatz von Wasser zu Steinen geformt und in hoher Weifsglut fertiggestellt. Diese Masse ist sehr plastisch und bedarf keines weiteren Bindemittels.This transition rock, albeit of much less carbonic acid content than magnesite, is also burned once, pulverized, and formed into stones by adding water and finished in a high glow of white. This mass is very plastic and does not need any further binding agent.
