In dem Patent 1 046 449 ist eine Vorrichtung zum aluminothermischen Zwischengußschweißen von Werkstücken, vorzugsweise Schienen, unter Schutz gestellt, die die für eine Zwischengußschweißung erforderliche Zeit stark vermindert.The patent 1 046 449 describes a device for the aluminothermic inter-cast welding of workpieces, preferably rails, placed under protection, which are necessary for an inter-cast weld Time greatly reduced.
Diese Vorrichtung ist im wesentlichen gekennzeichnet durch an einem anderen Ort vorgefertigte, aus feuerfestem Werkstoff bestehende Formkörper (Trockenform), die vorteilhafterweise in Einsatzkästen eingesetzt sind, durch eine Schnellspannvorrichtung zum Anpressen der Formkörper an die zu schweißenden Werkstücke und durch oberhalb der Formkörper angeordnete VoTwärmebrenner.This device is essentially characterized by prefabricated from another location Refractory material existing moldings (dry form), which are advantageously in insert boxes are used by a quick release device for pressing the molded body against the welding workpieces and by means of VoT heat burners arranged above the moldings.
Das Anpassen der Formkörper der Gießform an die verschiedenen Profile der zu schweißenden Schienen bzw. an den Abnutzungsgrad dieser Schienen wurde bisher so vorgenommen, daß durch einfache Abarbeitung diese Formkörper den Abmessungen der Schienen angepaßt wurden. Bei Verwendung1 von anderenorts hergestellten, getrockneten oder gebrannten, z. B. aus Schamotte bestehenden Trockenformen., die vorzugsweise aus seitengleichen Stücken gefertigt sind, ist dieses nicht ohne besondere Hilfsmittel möglich.The adaptation of the molded bodies of the casting mold to the different profiles of the rails to be welded or to the degree of wear of these rails has so far been carried out in such a way that these molded bodies were adapted to the dimensions of the rails by simple processing. When using 1 produced elsewhere, dried or fired, z. B. of chamotte existing dry forms., Which are preferably made of equal-sided pieces, this is not possible without special aids.
Bei der weiteren Ausbildung der im Hauptpatent geschützten Vorrichtung wurde nun gefunden, daß man den durch die vertikale Abnutzung1 des Schienenkopfes bedingten Spalt zwischen der Fertigform und der Oberseite des Schienenkopfes dadurch schließen kann, daß man in die oben offene Tröckenform feuerfeste Riegel, die z. B. durch dafür vorgesehene Nuten oder Ausnehmungen der Trockenform geführt werden, einsetzt. Unabhängig von dem vorhandenen Abnutzungsgrad der Schiene rutschen die Riegel immer so tief, daß sie auf der Schienenkopf-Fahrfläche aufliegen. Zuletzt wird die Riegelabdichtung durch Verfüllung der außen noch frei liegenden Fugen mit Klebsandbrei oder anderem Dichtungsstoff von den Außenseiten der Form her vorgenommen und die Riegel festgelegt.In the further training of the device protected in the main patent it has now been found that the gap caused by the vertical wear 1 of the rail head between the finished form and the top of the rail head can be closed by inserting fireproof bars into the open-topped Tröckenform z. B. are passed through grooves or recesses provided for this purpose in the dry form, uses. Regardless of the degree of wear and tear on the rail, the bars always slide so deep that they rest on the rail head runway. Finally, the transom sealing is carried out by filling the joints that are still exposed on the outside with adhesive sand paste or other sealing material from the outside of the mold, and the transom is fixed.
Aus der Zeichnung soll die Anordnung dieser Riegel näher erläutert werden. Es bedeuten 1 und 2 die zu schweißenden Schienen, 3 die Trockenforrn, 23 den Spalt zwischen Trockenform und Oberseite Schienenkopf, 15 die Einlaufkanäle für den aluminothermisch erschmolzenen Stahl, 19 die eingeschobenen Riegel Vorrichtung zum aluminothermischen.The arrangement of these bars is to be explained in more detail from the drawing. It means 1 and 2 the to welding rails, 3 the dry mold, 23 the gap between the dry mold and the top of the rail head, 15 the inlet channels for the aluminothermically melted steel, 19 the inserted bolts Device for aluminothermic.

und 21 den verbleibenden Steigerraum oberhalb des Schienenkopfes.and 21 the remaining riser space above the rail head.
Der aluminothermisch erschmolzene Stahl läuft durch einen oder die beiden Einlaufkanäle 15 ein, wobei der Stahl die Form vom Schienenfuß an bis zum Schienenkopf füllt. Der in der Form hochsteigende Stahl füllt auch den über dem Schienenkopf liegenden Raum zwischen den eingeschobenen Rieg'eln aus. Der dabei entstehende Steiger erlangt auf Grund der eingeschobenen Riegel eine geringere Breite, so· daß die Abschrotarbeit, die bei der Entfernung des Steigers zu leisten ist, vermindert wird.The aluminothermically melted steel runs through one or both inlet channels 15, wherein the steel fills the shape from the rail foot to the rail head. The one rising in shape Steel also fills the space above the rail head between the inserted bolts. Of the The riser resulting from this has a smaller width due to the inserted bolt, so that the Shredding work that has to be done when removing the riser is reduced.
