Description

Das Hauptpatent hat ein kombiniertes aluminothermisches Schweißverfahren zum Gegenstand, das dadurch gekennzeichnet ist, daß die Schienenköpfe durch Zwischenguß von aluminogenetischem Eisen, die Schienenfüße und -stege dagegen durch Zusammenstauchen nach Erwärmung durch aluminogenetische Schlacke verschweißt werden. Dieses Verfahren kann nun noch dadurch verbessert werden, daß man bei der Vorwärmung der zu schweißenden Schienenenden nicht, wie bisher üblich, den ganzen von der Form umschlossenen Teil der Schienen vorwärmt, sondern nur den Teil, der durch Zwischenguß mit aluminogenetischem Eisen verschweißt werden soll, nämlich die Schienenköpfe. Hierdurch wird die Zeitdauer der Vorwärmung wesentlich herabgesetzt, was eine Verkürzung der Arbeitszeit und eine wesentliche Ersparnis an Brennstoff ergibt. Versuche haben gezeigt, daß die Vorwärmung der Schienenköpfe allein fast in der halben Zeit durchgeführt werden kann wie die Vorwärmung der vollen Schienen.The main patent has a combined aluminothermic welding process for Object, which is characterized in that the rail heads by intermediate casting of aluminogenic iron, the rail feet and webs, on the other hand, by compression be welded after heating by aluminogenetic slag. This process can now be improved even further be that when preheating the rail ends to be welded not how Up to now it has been customary to preheat the entire part of the rails enclosed by the mold, but rather only the part that is to be welded by intermediate casting with aluminogenic iron, namely the rail heads. Through this the duration of the preheating is significantly reduced, which means a reduction in working time and significant savings of fuel. Tests have shown that the preheating of the rail heads alone takes almost half the time can be like preheating the full rails.
