Patentiert im Deutschen Reiche vom 4. Dezember 1909 ab.Patented in the German Empire on December 4, 1909.
Eisenschrott, Abfälle u. dgl. werden im allgemeinen nur als Zusatz bei dem Martin-Hochofenprozeß verwendet. Man hat jedoch auch schon vorgeschlagen, aus ihnen unmittelbar, d. h. ohne Umschmelzen, schlackenfreie und dichte Blöcke herzustellen. Dabei wurde in der Weise verfahren, daß man die Stücke zu Paketen vereinigte, diese auf Schweißhitze erwärmte und ausschmiedete. Durch dieScrap iron, scrap and the like are generally only used as an additive in the Martin blast furnace process used. However, it has already been suggested to use them directly, i. H. without remelting, slag-free and make dense blocks. This was done in such a way that the pieces combined into packages, heated to the heat of sweat and forged out. Through the
ίο Schläge beim Schmieden sollten nicht nur die Stücke zu einem Block vereinigt, sondern auch aus letzterem die ihnen anhaftende Schlacke ausgetrieben werden. Dabei wird das Paket aber jeweils nur in einer Richtung bearbeitet, so daß ein restloses Austreiben der Schlacke nicht möglich ist, auch wenn man das Paket nach einigen Schlägen wendet und in anderer Richtung bearbeitet. Es wird wohl ein Teil der Schlacke ausgetrieben, deren größter Teil verbleibt aber im Innern des Paketes und erfährt durch das Schmieden nur eine Umlagerung.ίο Strikes when forging shouldn't just be that Pieces combined into a block, but also from the latter the clinging to them Slag to be expelled. The package is only sent in one direction processed so that a complete expulsion of the slag is not possible, even if you turns the package after a few blows and processes it in the other direction. It will be Part of the slag is driven out, but most of it remains inside the Package and only experiences a relocation through forging.
Es lassen sich nun schlackenfreie dichte Blöcke aus Eisenschrott, Abfällen u. dgl. ohne Umschmelzen herstellen, indem die zu Paketen vereinigten, auf Schweißhitze erwärmten Eisenstücke unmittelbar und gleichzeitig in Richtung aller drei Dimensionen des Raumes einem Druck in einer Presse ausgesetzt werden, bei welcher zum Ausquetschen der den einzelnen Stücken anhaftenden Schlacke und zum Beseitigen der Hohlräume im Innern des Paketes in Richtung der Resultanten aus den Druckkräften zwischen den gegeneinander bewegten Flächen der Presse Schlitze frei bleiben, die dem Vorbewegen der Flächen entsprechend verengert werden und in deren Endstellung geschlossen sind. Es ist also von Wichtigkeit, daß auf das Paket unmittelbar und gleichzeitig in Richtung aller drei Dimensionen des Raumes Druck ausgeübt wird. In dieser Weise wirkende Pressen sind zwar an sich bekannt ; sie sind indessen bisher nur benutzt worden, um bei dem Erstarren von flüssigem Eisen die Bildung der sogenannten Lunker zu verhindern. Der Hohlraum einer solchen Presse ist unten und an den Seiten sorgfältig dicht zu halten, um das Ausfließen des flüssigen Gußeisens zu verhindern. Durch den während des Verfahrens auf das flüssige Eisen ausgeübten Druck wird auch keine Verdichtung angestrebt. Vielmehr soll er nur ganz allmählich, und zwar in dem Maße gesteigert werden, wie infolge der Abkühlung das Volumen des Eisens abnimmt.Dense blocks of scrap iron, waste and the like, free of slag, can now be made without Produce remelting by combining the pieces of iron that have been heated to welding heat and combined into packets directly and simultaneously in the direction of all three dimensions of space Pressure in a press is used to squeeze the individual Pieces of adhering slag and to remove the voids inside the package in the direction of the resultants from the compressive forces between those moved against each other Areas of the press slots remain free, which correspond to the advancement of the areas are narrowed and are closed in their end position. So it is important that on the package immediately and simultaneously in the direction of all three dimensions of the Space pressure is exerted. Presses acting in this way are known per se ; however, they have hitherto only been used for the solidification of liquids Iron to prevent the formation of the so-called blowholes. The cavity of such a press must be carefully sealed at the bottom and sides to prevent the liquid cast iron from flowing out to prevent. By the exerted on the liquid iron during the procedure Pressure is also not aimed for compression. Rather, it should only be very gradually, and it can be increased to the extent that, as a result of the cooling, the volume of the iron decreases.
Gemäß der Erfindung werden dagegen absichtlich zwischen den gegeneinander bewegten Flächen der Presse Schlitze frei gelassen, durch welche die Schlacke austreten kann. Die Schlitze liegen in Richtung der Resultanten aus den Druckkräften, also gerade da, wohin sich die Schlacke unter dem Einfluß der Druckkräfte ohnehin drängt. Da. die Menge der in der Zeiteinheit austretenden Schlacke geringer wird, so ist noch dafür Sorge getragen, daß die Schlitze dem Vorbewegen der Flächen entsprechend verengert werden und in deren Endstellung geschlossen sind. Infolgedessen kannAccording to the invention, however, are intentionally moved between the Areas of the press slots left free through which the slag can exit. the Slots are in the direction of the resultants from the compressive forces, i.e. exactly where they go the slag pushes itself anyway under the influence of the pressure forces. There. the amount of in the slag emerging from the unit of time is less, care must be taken that the slots are narrowed according to the advancement of the surfaces and in their end position are closed. As a result, can
