Description

Verfahren zum Verschweißen von Schrottpaketen Metallabfälle, wie z. B. Eisenschrott, werden vielfach in der Weise wiederverwertet, daß man sie gebündelt oder zu Paketen gepackt den Schmelzöfen, wie z. B. den Kupolöfen, den Martinöfen usw., zusetzt, um auf diese Weise durch Umschmelzen das Metall wiederzugewinnen, oder sie werden auch, wenn es sich beispielsweise um schmiedeeiserne Abfälle handelt, ebenfalls gebündelt oder zu Paketen gepackt in Kohle- oder Koksfeuern auf Schweißtemperatur erhitzt, und dann durch Hämmern, Pressen, Walzen usw. zusammengeschweißt, um weiterverarbeitet zu werden.Process for welding scrap packages metal waste, such as. B. scrap iron are often recycled in such a way that they are bundled or packed in packages to the melting furnaces, e.g. B. the cupolas, the martin furnaces etc., added in order to regain the metal by remelting, or they are also, if it is, for example, wrought iron waste, also bundled or packed in packages in coal or coke fires at welding temperature heated, and then welded together by hammering, pressing, rolling, etc. for further processing to become.

Vorliegende Erfindung betrifft ein Verfahren zum Verschweißen von Schrottpaketen durch Erhitzen und nachfolgendes Hämmern, Pressen oder Walzen, doch soll bei diesem Verfahren die Erhitzung der Pakete auf Schweißtemperatur nicht in Kohle- oder Koksfeuern erfolgen, sondern durch elektrische Wirbelströme, die man in ihnen erzeugt. Wenn man beispielsweise ein oder mehrere Pakete mit einem Kupferring oder Kupfermantel umgibt, um den man einen geeigneten Wechselstrom leitet, so wird durch die sich in dem Schrottpaket bildenden Wirbelströme das Paket von innen heraus, ohne daß die Zufuhr äußerer Wärme notwendig wäre, erhitzt. Die Wärme steigert sich, es entsteht allmählich Rotglut, bis schließlich helle Weißglut zu bemerken ist. Das Paket befindet sich dann auf Schweißtemperatur. Man braucht es dann nur zu hämmern, zu pressen oder zu walzen. um Schmiedeeisengegenstände bzw. Walzeisen daraus zu erhalten.The present invention relates to a method for welding Scrap packages by heating and subsequent hammering, pressing or rolling, yes in this process, the heating of the packets to the welding temperature should not occur Coal or coke fires take place, but by electrical eddy currents, which one generated in them. For example, if you have one or more packages with a copper ring or surrounds a copper jacket, around which a suitable alternating current is passed through the eddy currents forming in the scrap package, the package from the inside out, heated without the need to supply external heat. The warmth increases it gradually develops red heat, until finally a bright white heat is noticeable. The package is then at welding temperature. Then all you have to do is hammer it to press or to roll. to make wrought iron objects or rolled iron from it obtain.

Gegenüber der Erhitzung der Bündel oder Pakete in Puddel- oder Schweißöfen besteht bei vorliegendem Verfahren der Vorteil, daß man ohne Ofen und mit wesentlich geringerem Abbrand arbeitet, besonders wenn die Erhitzung der Pakete in reduzierender Atmosphäre vorgenommen wird. Außerdem ist die Temperaturregelung einfach, da sie durch entsprechende Einstellung des elektrischen Stromes erfolgt.Compared to the heating of the bundles or packages in puddle or welding ovens there is the advantage in the present process that one without a furnace and with substantially Lower burn-up works, especially when the heating of the packets is in reducing Atmosphere is made. Also, temperature control is easy as it by adjusting the electric current accordingly.
