KAISERLICHESIMPERIAL
PATENTAMTPATENT OFFICE
Das Verfahren soll in der Hauptsache dazu dienen, Oefen, welche sehr hohe Temperaturen zu erzeugen haben, mit einer Schicht reiner, möglichst dichter Kieselmasse zu versehen, kann aber naturgemäfs auf alle Materialien ausgedehnt werden, die in hoher Hitze in einen plastischen Zustand kommen. Das Verfahren ist folgendes: Wenn der Ofen in der höchsten Hitze ist, sind die inneren Flächen desselben weich, befinden sich also in einem plastischen Zustande, welcher bedingt, dafs gegen dieselben fliegendes Material an den Flächen haftet oder sich auch einbohrt. Das in entsprechender Korngröfse vorbereitete Ofenfuttermaterial, z. B. reiner Quarz, wird dann in den heifsen Ofen vermittelst eines Gebläses beliebiger Construction eingebracht bezw. auf die bei hoher Hitze im plastischen Zustande befindlichen Innenflächen aufgeblasen, so dafs es an diesen haftet oder sich auch einbohrt. Man kann auf diese Weise den ganzen Ofen innen mit einer Schicht Futtermaterial überziehen , dann wieder aufheizen, eine zweite, dritte und vierte Schicht appliciren und so fort, bis man die genügende Stärke erreicht hat. Ebensowohl kann man das Verfahren zur Ausbesserung einzelner schadhafter Stellen im Ofenherd oder dem Ofengewölbe benutzen; es ist also für Ofenbau und Ofenreparatur verwendbar. The main purpose of the process is to use ovens which have very high temperatures have to be provided with a layer of pure, as dense as possible pebble mass, but can of course be extended to all materials that are exposed to high heat in come to a plastic state. The procedure is as follows: When the furnace is in the is the highest heat, the inner surfaces of it are soft, that is, they are in one plastic state, which causes material flying against them to reach the Surfaces sticks or bores. The furnace lining material prepared in the appropriate grain size, z. B. pure quartz, is then introduced respectively into the hot furnace by means of a fan of any construction. on the inner surfaces, which are in a plastic state at high heat, are inflated, so that it adheres to these or bores into them. You can use the whole oven this way cover the inside with a layer of lining material, then heat up again, a second, apply third and fourth coats, and so on, until sufficient thickness is obtained. You can also use the method for repairing individual damaged areas in the Use the stove or the oven vault; it can therefore be used for furnace construction and repair.
Der grofse Vortheil dieses Verfahrens der Herstellung von Ofenfuttern aus reiner Kieselmasse ist einleuchtend, da auf einfachere Weise ein absolut dichtes, also thunlichst feuerbeständiges Futter nicht hergestellt werden kann. Ein zur Ausführung dieses Verfahrens dienender transportabler Apparat ist auf der beiliegenden Zeichnung schematisch dargestellt. Mit einem entsprechend eingerichteten Vorgelege V wird ein Windrad W in Bewegung gesetzt und ein Windstrom erregt, der in einer Düse D mit einem Strahl des Futtermaterials zusammentrifft, welcher einem Behälter B entrinnt. Luftstrom und Materialzuflufs sind regulirbar.The great advantage of this method of making furnace linings from pure pebble is evident, since an absolutely dense, and therefore most fire-resistant, lining cannot be made in a simpler way. A portable apparatus used to carry out this process is shown schematically in the accompanying drawing. A wind turbine W is set in motion with a correspondingly set up gear train V and a current of wind is excited which, in a nozzle D , meets a jet of the fodder material which escapes from a container B. Air flow and material inflow can be regulated.
An die Düse D schliefst sich der Mischraum für Ofenfuttermaterial und Luft, so dafs von einem Mundstück M aus ein Strahl des vom Luftstrom getragenen Materials in den Ofen O eingeblasen werden kann. Die Anordnung des Mundstückes bezw. seine Verbindung K mit dem übrigen Apparat ist beweglich angeordnet, um mit dem Materialstrahl die Innenflächen des Ofens sämmtlich beblasen zu können. Vorgelege, Windrad und Materialbehälter sind auf einem fahrbaren Karren oder Wagen montirt.The mixing space for furnace lining material and air closes at the nozzle D , so that a jet of the material carried by the air stream can be blown into the furnace O from a mouthpiece M. The arrangement of the mouthpiece respectively. its connection K with the rest of the apparatus is movably arranged in order to be able to blow all the inner surfaces of the furnace with the material jet. Transmission, wind turbine and material container are mounted on a mobile cart or wagon.
Bei gröfseren Oefen, wo es gilt, den Materialstrom weit und mit Kraft zu werfen, ist es vorzuziehen, anstatt mit Luft direct mit Dampf zu blasen und, um das so eingebrachte Material trocken zu erhalten, den Dampf vermittelst eines geeigneten Heizapparates zu überhitzen. In larger furnaces, where it is necessary to throw the material flow far and with force, it is preferable to blowing directly with steam instead of air and around the material thus introduced to keep it dry, to superheat the steam by means of a suitable heating device.
