 selbe Spiel wiederholt sich, bis die Blöcke kein Eisen mehr aufnehmen und der Erstarrungprozess beendet ist. Ein allzuhäufiges Nachgiessen macht   man zweckmässigerweise   dadurch unnötig, dass man am oberen Ende des Trichters ein   Reservoi. a   anbringt (Fig. 1) und dieses nach der Abkühlung der Oberfläche mit flüssigem Eisen   füllt.   



   Auf diese Weise erreicht man mit Sicherheit, dass auch die schwersten Blöcke völlig   lunker-   frei werden, und zwar nicht nur in ihrem oberen Teile, sondern auf ihrer ganzen Länge. Die Aus- übung des Verfahrens ist sehr einfach und die Kosten sind verschwindend gering. Ferner wird bewirkt, dass die Seigerungsprodukte, die bekanntlich ihres niedrigen Schmelzpunktes wegen bis zuletzt flüssig bleiben, in den Blockkopf   hinugedrückt   und im nutzbaren Teil des Blockes durch reines Material, das aus dem   Giesstlichter stimmt,   ersetzt werden. Infolgedessen zeigen Blöcke, die nach dem vorliegenden Verfahren behandelt sind, in allen ihren Teilen eine sehr gleichmässige Zusammensetzung. 



   Das Aufgiessen von Wasser auf die Blockköpfe kann nach erfolgter Erstarrung der Oberfläche weiter fortgesetzt und dadurch die Abkühlung   1es   ganzen Blockes beschleunigt werden, wenn die Qualität des Materials diese   Massnahme gestattet.   Im übrigen kann die Erstarrung

 The same game is repeated until the blocks no longer take up iron and the solidification process is over. Too frequent refilling is expediently made unnecessary by having a reservoir at the upper end of the funnel. a attaches (Fig. 1) and this fills with liquid iron after the surface has cooled down.



   In this way you can be sure that even the heaviest blocks will be completely free of voids, not only in their upper part, but along their entire length. The procedure is very easy to carry out and the costs are negligible. Furthermore, the result is that the segregation products, which are known to remain liquid until the end due to their low melting point, are pressed into the block head and replaced in the usable part of the block by pure material that is right from the pouring light. As a result, blocks treated according to the present process show a very uniform composition in all their parts.



   The pouring of water onto the block heads can be continued after the surface has solidified and thereby the cooling of the whole block can be accelerated if the quality of the material allows this measure. Otherwise, the solidification

PATENT-ANSPRUCH : Verfahren zur Herstellung dichter Flusseisenblöcke durch Giessen von unten, dadurch gekennzeichnet, dass die Oberfläche des einfliessenden Materials bei Erreichung der gewünschten Block- höhe durch Aufgiessen von Wasser, Aufblasen eines Luftstromes oder dgl. sonstige künstliche Kühlung zum sofortigen Erstarren gebracht und durch einmaliges oder mehrmaliges Nachfüllen bewirkt wird, dass die bei der Erstarrung entstehenden Hohlräume während des Erstarrungs vorganges von unten her durch unter Druck stehendes flüssiges Flusseisen ausgefüllt werden PATENT CLAIM: Process for the production of dense river iron blocks by pouring from below, characterized in that the surface of the inflowing material is made to solidify immediately when the desired block height is reached by pouring water, blowing an air stream or similar other artificial cooling and refilling it once or several times the effect is that the cavities that arise during the solidification are filled from below during the solidification process by liquid iron under pressure
