Description

Verfahren zur Herstellung von Schienen Gemäß dem Patent 490 283 werden Schienen mit im Kopf in der Längsrichtung liegenden mehreren gleichgerichtet verlaufenden Einlagen aus Hartstahl, die mit dem Weichstahl verschweißt sind, derart hergestellt, daß die Hartstahleinlagen gitter- oder rostartig in die Kokille eingesetzt sind und mit dem Weichstahl umgossen werden.Process for the manufacture of splints According to the patent 490,283 Rails with several in the same direction lying in the head in the longitudinal direction Inlays made of hard steel, which are welded to the mild steel, manufactured in such a way that that the hard steel inserts are used like a grid or rust in the mold and cast around with the mild steel.

Gemäß der Erfindung soll nun eine bedeutend vereinfachte Herstellung derartiger V erbundgußblöcke dadurch erzielt werden, daß die in die Kokille eingesetzten nebeneinanderliegenden Hartstahleinlagen aus einem einzigen schlangenförmig gebogenen Werkstoffstreifen bestehen. Anstatt eines einzigen schlangenförmig gebogenen Streifens können gemäß der Erfindung auch mehrere einzelne nebeneinanderliegende Hartstahleinlagen Verwendung finden, deren Enden jeweils oben und unten abwechselnd derart miteinander verbunden sind, daß älle Einlagen einen fortlaufend schlangenförmigen Streifen bilden.According to the invention, a significantly simplified production is now intended Such V erbundgußblockblocks can be achieved in that the inserted into the mold adjacent hard steel inserts made of a single serpentine curved Material strips exist. Instead of a single serpentine curved strip According to the invention, several individual hard steel inserts lying next to one another can also be used Find use, the ends of which alternate with each other at the top and bottom are connected that all deposits form a continuous serpentine strip.

Weiterhin ist noch Gegenstand der Erfindung, daß der derart ausgebildete, in die Kokille eingesetzte schlangenförmige Werkstoffstreifen vor bzw. während des Eingusses des Weichstahles durch elektrische Widerstandserhitzung auf eine möglichst hohe Temperatur gebracht wird, wie es an sich zwecks inniger Verbindung zweier Stahlsorten bekannt ist. Bei einer Vorwärmung dieses schlangenförmigen Werkstoffstreifens auf etwa 90o bis 120o° durch elektrische Widerstandserhitzung, welche in der bisherigen Art der Einsetzung der mehreren nebeneinanderliegenden Hartstahleinlagen nicht erzielt werden konnte, wird eine außerordentlich billige und sichere Verschweißung der Werkstoffsorten gewährleistet, so daß die aus diesen Blöcken ausgewalzten Verbundschienen den an sie gestellten Anforderungen durchaus gewachsen sind.The invention also relates to the fact that the serpentine strips of material inserted into the mold before or during the Injection of the mild steel by electrical resistance heating to as much as possible high temperature is brought, as it is for the purpose of intimate connection between two types of steel is known. When this serpentine strip of material is preheated about 90o to 120o ° by electrical resistance heating, which in the previous Type of insertion of several adjacent hard steel inserts not achieved could be an extremely cheap and safe welding of the types of material guaranteed, so that the composite rails rolled out of these blocks to the they are well able to cope with the demands placed on them.

In der Zeichnung sind zwei Ausführungsbeispiele der Erfindung dargestellt, und zwar zeigen Abb. i und 2 einen einzigen schlangenförinig gebogenen Werkstoffstreifen, dessen Windungen mehrere etwa parallel verlaufende Einlagen bilden, Abb. 3 und ¢ einen fortlaufenden schlangenförmigen Streifen, dessen einzelne nebeneinanderliegende Teile 1, 2, 3, q., 5, 6, 7, 8, 9, J o an ihren Enden durch mit den einzelnen Streifen verschweißte OOuerstücke ii derart verbunden sind, daß ein fortlaufender Streifen entsteht.In the drawing, two exemplary embodiments of the invention are shown, namely, Fig. i and 2 show a single serpentine curved strip of material, the turns of which form several layers running approximately parallel, Fig. 3 and ¢ a continuous serpentine strip, its individual adjacent Parts 1, 2, 3, q., 5, 6, 7, 8, 9, J o at their ends with the individual strips welded OOuerstücke ii are connected in such a way that a continuous strip arises.
