In dem Patent 1 046 449 ist eine Schweiß vorrichtung für die aluminothermische Zwischengußschweißung von Werkstücken, vorzugsweise Schienen, unter Schutz gestellt, die die für eine Zwischengußschweißung erforderliche Zeit stark vermindert.In the patent 1 046 449 there is a welding device for the aluminothermic inter-cast welding of workpieces, preferably rails, under Provided protection that greatly reduces the time required for an inter-cast weld.
Diese Schweißvorrichtung ist gekennzeichnet durch anderenorts vorgefertigte, aus feuerfestem Werkstoff bestehende Trockenformen, die vorteilhafterweise in einen Einsatzkasten eingesetzt sind, durch eine Schnellspannvorrichtung zum Anpressen der Formkörper an die zu schweißenden Werkstücke und durch einen oder mehrere im oberen Teil des Steigers innerhalb der Trockenform angeordnete Vorwärmebrenner. Die Flammen dieser Vorwärmebrenner schlagen in den breiten, als Steiger dienenden Kanal der Trockenform und streichen über den Schienenkopf bis zu dem Schienenfuß. This welding device is characterized by prefabricated elsewhere, made of refractory material existing dry forms, which are advantageously used in an insert box, by a Quick clamping device for pressing the moldings onto the workpieces to be welded and through one or more preheat burners arranged in the upper part of the riser inside the dry mold. The flames of these preheating burners hit the wide channel that serves as a riser the dry form and stroke over the rail head up to the rail foot.
Bei der Schweißvorrichtung nach, dem Hauptpatent wurde gefunden, daß die z. B. aus Schamotte, Keramik oder anderem feuerfestem Werkstoff bestehenden, 20, anderenorts vorgefertigten Trockenformen oder die nach dem C O2-Erstarrungsverfahren hergestellten Formen sich beim Brand oder bei der Trocknung verziehen können und dadurch sich nur schwer an die zu schweißenden Werkstückenden bzw. Schienen anpressen lassen oder wenn deren Querschnittsprofil von demjenigen des Modells abweicht. In solchen Fällen besteht für die harten Formen beim Andrücken an das Werkstück die Gefahr des Zerbrechens.In the welding device according to the main patent it was found that the z. B. made of fireclay, ceramic or other refractory material, 20, elsewhere prefabricated dry molds or the molds produced by the CO 2 solidification process can warp during fire or drying and thus only press against the workpiece ends or rails to be welded with difficulty or if their cross-sectional profile differs from that of the model. In such cases, there is a risk of the hard forms breaking when pressed against the workpiece.
Es wurde nun gefunden, daß sich z. B. aus Eisenberger Klebsand am Ort der Schweißung gestampfte
oder gerüttelte Formen in der Vorrichtung nach dem Hauptpatent besser eignen, da sie sich beim Trocknen
nicht verziehen. Dadurch ist es möglich, die Wandstärke dieser Form wesentlich dünner zu halten, so
daß das Trocknen der Form schnell erfolgt und das Vorrichtung zum aluminothermischen
Zwischengußschweißen von SchienenIt has now been found that z. B. from Eisenberger adhesive sand tamped or jogged forms in the device according to the main patent at the location of the weld are better because they do not warp when drying. This makes it possible to keep the wall thickness of this form much thinner, so that the drying of the form takes place quickly and the device for aluminothermic
Inter-cast welding of rails
