Description

Aktiengesellschaft Buderus'sche Eisenwerke in Wetzlar Verfahren zum Abkühlen von Emailfluß Bei der Herstellung von Email wird bisher in, der Regel so vorgegangen, daß die fertige Emalilschmelze zwecks Abkühlung in einen Wasserbehälter geleitet wird. Das Email wird' auf diese Weise sehr plötzlich abgekühlt und zerspringt dabe!_ in kleine Stücke, die sogenannten Granalien. Diese Methode hat di:in Vorteil großer Einfachheit, besitzt aber zugleich auch einige Nachteile. Da es sich um ein Maßverfahren handelt, müssen nämlich die granulierten Stücke unterAufwiaind besonderer Einrichtungen und Energie getrocknet werden. Außerdem sind' die Stücke sehr hart, so daß für den später erforderlichen Nlahlprozeß verhältnismäßig starke Mahlvorrichtungen eingesetzt werden müssen. Diese Mängel sollen durch &e Erfindung dadurch behoben werden, daß die schmelzflüssige Emailleasse in beliebiger Weise, z. B. mit Wasser, Dampf oder Gas. aufgeschäumt wird. Das Schäumverfahren ist auf anidieren Gebieten der Technik bereits bekannt, in erster Linie bei der Verwertung von Hochofenschlacke, die auf diese Weise in Schaumschlacke oder Hüttenbims verwandelt wird. Bekanntlich wird dabei die flüssige Schlacke in eine Rinne oder in Behälter geleitet, die vorher mit Wasser benetzt worden sind. Diese geringe unter der Schlacke befindliche Wassermenge wird sofort in Dampf verwandelt und bläht die: Schlucke auf, die sich dabai in einen von Poren durchsetzten Körper verwandelt, der nun eine ganz geringe Festigkeit besitzt. In grundsätzlich gleicher Weise wird nach ,der Erfindung vorgegangen. An Stelle von Wasser kann naturgemäß @aiuch Dampf oder ein beliebiges Gas zum Polli@g machen des Emailflusses verwead#et werden. Das aufgeschäumte Email ist praktisch trocken und lcarqni unter geringstem Energieaufwaind gemahlen werden. Für die Durchführung des Verfahrens sind alle für andere Zwecke bekannten Schäumvorrichtungen verwendbar. Es können also Räder, Trommeln, Saheibeni oder sonstiige bewegliche, aber auch unbewegliche Rinnen, Behälter u. dgl. benutzt werden. Selbstverständlich ist im Rahmen der Erfindung auch die Anwendung anderer Schäumv erfahren, z. B. mit festen Schäummitteln, denkbar.Aktiengesellschaft Buderus'sche Eisenwerke in Wetzlar Procedure for Cooling down of the enamel flow In the manufacture of enamel, this has usually been the case up to now proceeded that the finished enamel melt for the purpose of cooling in a water container is directed. In this way, the email is very suddenly cooled and cracked dabe! _ in small pieces, the so-called granules. This method has di: an advantage great simplicity, but also has some disadvantages. Since it is a This is because the granulated pieces have to take a special effort Facilities and energy to be dried. In addition, the pieces are very hard, so that relatively strong grinding devices for the later required grinding process must be used. These deficiencies are intended to be remedied by the invention be that the molten enamel leash in any way, for. B. with water, Steam or gas. is foamed. The foaming process is in anidate areas already known to the technology, primarily in the recovery of blast furnace slag, which is transformed in this way into foamed slag or smelting pumice. As is well known the liquid slag is fed into a channel or container that was previously installed have been wetted with water. This small amount of water under the slag is instantly transformed into steam and inflates the: gulps that dabai into one body interspersed with pores transformed, which now has a very low firmness. The procedure for the invention is basically the same. Instead of of water can of course make @aiuch steam or any other gas to polli @ g of the email flow. The foamed enamel is practically dry and lcarqni can be ground with the least amount of energy. For the implementation of the process, all foaming devices known for other purposes can be used. So it can be wheels, drums, Saheibeni or other movable, but also immovable Gutters, containers and the like can be used. It goes without saying that this is within the scope of the invention also experience the application of other Schäumv, z. B. with solid foaming agents, conceivable.
