Abstract

1. A heavy-current plasmatron nozzle consisting of a single interchangeable insert (1) in the general form of a wearing element disposed centrally with respect to the cathode (4), a cooling jacket being provided for the nozzle, characterized in that the insert (1) is secured directly int he nozzle body by means of a solder (2) and the nozzle cooling is so adapted that the solder does not melt while the burner is in operation.

Düse für ein HochstromplasmatronNozzle for a high current plasma sir

Anwendungsgebiet der ErfindungField of application of the invention

Die Erfindung betrifft Piasmatrone mit hoher elektrischer Leistung zuJi Einsatz in Schmelzöfen,The invention relates to high-power Piasmatrone for use in furnaces,

Charakteristik der bekannten technischen LösungenCharacteristic of the known technical solutions

Piasmatrone zua Schweißen, Schneiden und Schmelzen von Werkstoffen sind bekannt« Sie bestehen zumeist aus einem Katodenblock, der Katode und dem Kühlmantel mit einer die Katode umgebende Düse. Das plasmabildende Gas strömt zwischen Katode und Düse,Piasmatrone zua Welding, cutting and melting of materials are known «They usually consist of a cathode block, the cathode and the cooling jacket with a nozzle surrounding the cathode. The plasma-forming gas flows between cathode and nozzle,

Bei Plasmatronen mit Stromstärken von mehreren kA sind die Düsen durch sehr hohe Temperaturen und Nebenbogenbildung einen starken Verschleiß unterworfen. Ihre Haltbarkeit beträgt nur einige Stunden. Es wurde versucht, zur Erhöhung der Lebensdauer die geometrische Form der Düse zu verändern, ihre Kühlung zu verbessern und wie im Vv1P 131218 beschrieben, die Düse aus mehreren Ringen zu fertigen, die mit einer Gleitdichtung aufgesetzt und durch Verschraubung oder Bajonettverschluß befestigt v/erden.In the case of plasma cartridges with currents of several kA, the nozzles are subject to very high temperatures due to very high temperatures and secondary arcing. Their durability is only a few hours. It was tried to increase the life of the geometric shape of the nozzle to improve their cooling and as described in Vv 1 P 131218, to manufacture the nozzle of several rings, which fitted with a sliding seal and secured by screwing or bayonet closure v / earth.

Ziel der ErfindungObject of the invention

Das Ziel der Erfindung besteht in der Senkung des Materialaufwandes für die Reparatur, der Verringerung der Reparaturzeit und der Reparaturkosten bei gleichzeitiger Erhöhung der Lebensdauer der Düse,The object of the invention is to reduce the cost of materials for the repair, reducing the repair time and the repair costs while increasing the life of the nozzle,

Dp.riegung des Tesens der Erfindung Discussion of the Tent of the Invention

vij.*d die Aufgabe dadurch gelöst, daß die Düse des Placmatrons mit einem Düseneinsatz als Verschleiß-The object is achieved in that the nozzle of the Placmatrons with a nozzle insert as wear

teil ausgerüstet ist, welches zentrisch um die Katode durch Einlöten in den Düsenkörper befestigt wird,Part is fitted, which is fixed centrally around the cathode by soldering in the nozzle body,

Ausführungsbeispielembodiment

Die Erfindung wird anhand der Zeichnung näher erläutert. Der als Verschleißteil ausgebildete Düseneinsatz 1 ist mittels des Lotes 2 im Düsenkörper· 3 zentrisch um die Katode 4 befestigt« Während der Betriebszeit des Brenners wird die Düse so gekühlt, daß ein Aufschmelzen des Lotes nicht erfolgt. Nach eingetretenem Verschleiß des Düseneinsatzes 1 wird durch Erwärmen der Düse das Lot 2 aufgeschmolzen und damit der Düseneinsatz 1 vom Düsenkörper 3 getrennt. Nachfolgend wird der neue Düseneinsatz 1 mit dem Düsenkörper 3» wie oben beschrieben, verbunden.The invention will be explained in more detail with reference to the drawing. The trained as wearing part nozzle insert 1 is fixed by means of the solder 2 in the nozzle body · 3 centrally around the cathode 4. During the operating time of the burner, the nozzle is cooled so that a melting of the solder does not occur. After the wear of the nozzle insert 1, the solder 2 is melted by heating the nozzle and thus the nozzle insert 1 is separated from the nozzle body 3. Subsequently, the new nozzle insert 1 with the nozzle body 3 »is connected as described above.
