KLASSE 49 g·.CLASS 49 g ·.

Die Verarbeitung des Metallkleins geschah bisher in der Weise, dafs dasselbe direct niedergeschmolzen und das erhaltene Metall dann in Formen gegossen wurde. Beim Niederschmelzen des Metallkleins erlitt dasselbe infolge der lockeren Beschaffenheit des Materials und vor allem beim wiederholten Nachfüllen desselben wegen des wiederholten Luftzutrittes bedeutenden Abbrand, und jnfolge des flüssigen Zustandes des Metalles konnten nur die vorräthigen Formen mit solchem gefüllt, also Faconstücke nur in sehr beschränkter Zahl hergestellt werden. ' Auch waren die Gufsstücke meist porös und nutzten sich verschieden ab. Sollte das erhaltene flüssige Metall zu Blech verarbeitet werden, so mufste dasselbe entweder zu Blöcken gegossen werden, worauf diese dann nach nochmaligem Glühen ausgewalzt wurden, oder es mufste vor dem Auswalzen, nachdem es fest geworden war, zu viereckigen Blöcken unter dem Dampfhammer zusammengeschlagen und darauf nochmals geglüht werden.The processing of the small metal has hitherto been done in such a way that it is melted down directly and the metal obtained is then in Molds was poured. When the small metal was melted down, the same suffered as a result of loose nature of the material and especially when it is refilled repeatedly Significant burn-off because of the repeated admission of air, and as a result of the liquid state of the metal, only the forms in stock could be filled with such, that is, shaped pieces can only be produced in very limited numbers. 'The castings were also mostly porous and worn out differently. The liquid metal obtained should be processed into sheet metal then it either had to be cast into blocks, whereupon these then were rolled out after being re-annealed, or it had to be rolled out after it had become solid, pounded into square blocks under the steam hammer and then annealed again.

Diesen Uebelstä'nden wird durch das vorliegende Verfahren abgeholfen. Dasselbe besteht darin, dafs das niederzuschmelzende Material vorher in geeigneten Pressen bei einem Druck, der je nach dem Metall verschieden ist, in Formen geprefst wird, worauf diese Prefsstücke im Schweifs- oder in einem anderen Ofen geglüht und darauf sofort zu Blech ausgewalzt oder in Matrizen zu Fagonstücken geprefst werden.These problems are remedied by the present procedure. The same exists in that the material to be melted down beforehand in suitable presses at a pressure which differs according to the metal is, is pressed in forms, whereupon these Prefsstück in tail or in a Annealed in another furnace and then immediately rolled out to sheet metal or in dies to form Fagon pieces be pressed.

Hierbei wird der Abbrand auf ein Minimum reducirt, das Niederschmelzen überflüssig, viel Zeit erspart und billiger gearbeitet, da die Anlage einfacher und weniger umfangreich zu sein braucht.Here the burn-up is reduced to a minimum, the melting down is superfluous, much Time saved and cheaper because the system is simpler and less extensive needs to be.

Auch wird ermöglicht, dafs viel mehr Faconstücke mittelst der Presse hergestellt werden können, als dies durch das bisherige Verfahren des Giefsens in Formen möglich war; ferner wird erzielt, dafs Prefsstücke von gleichmäfsigerem Gefüge und gröfserer Dichte erhalten werden, die sich weniger und gleichmäfsiger abnutzen als die Gufsstücke; schliefslich sind die nach dem neuen Verfahren erhaltenen Bleche frei von Schlacke.It is also made possible that many more shaped pieces can be produced by means of the press can be, as this is possible by the previous method of Giefsens in forms was; furthermore it is achieved that prefabricated pieces of a more uniform structure and greater density are obtained that wear less and more evenly than the cast pieces; finally the sheets obtained by the new process are free of slag.

Es ist bereits früher vorgeschlagen worden, fein vertheilte Metalle dadurch zum Einschmelzen geeignet zu machen, dafs man sie zu festen Kuchen zusammenprefste (vergl. Kerl, Grundrifs der Metallhüttenkunde, Aufl. 2; Wedding, schmiedbares Eisen; Borchers, Elektrometallurgie).It has previously been proposed to melt finely divided metals thereby suitable to be pressed together into firm cakes (cf. Grundrifs der Metallhüttenkunde, ed. 2; Wedding, malleable iron; Borchers, Electrometallurgy).

Das Verfahren der vorliegenden Erfindung ist jedoch von jenen sowohl in Bezug auf das Ausgangsmaterial als auch auf das zu erzielende Resultat vollkommen verschieden. Denn es handelt sich bei den früheren Verfahren lediglich um das Brikettiren von elektrolytisch niedergeschlagenen, also sehr fein vertheilten Metallen, wie Cementkupfer oder Blei-, Silber- oder Eisenschwamm, und nicht, wie im vorliegenden Verfahren, um grobe Metallspähne, also um Metallabfälle, wie dieselben bei der mechanischen Metallbearbeitung erhalten werden.However, the method of the present invention is different from those of both The starting material and the result to be achieved are completely different. For it in the earlier processes it is only a matter of briquetting electrolytically precipitated, thus very finely divided metals, such as cement-copper or sponge lead, silver or iron, and not, as in the present case Process for removing coarse metal chips, i.e. metal waste, such as those obtained from mechanical metalworking will.
