Description

Verfahren zur Herstellung von Ventilkegeln, die im Teller eine erweiterte Höhlung aufweisen Zur Herstd, lung von Ventilkegeln, die im Teller eine erweiterte Höhlung aufweisen, ist eine Reihe von Verfahren bekanntgeworden. Die Erfindung bezieht sich auf solche Kegel, bei denen ein Ventilkörper mit vorbearbeiteter, etwa tulpenförmiger Höhlung durch einen Deckel abgeschlossen wird, und betrifft im besonderen idie Durchführung der Schweißung.Process for the production of valve cones, which have an expanded position in the plate Have a cavity For the production of valve cones that have an enlarged in the plate Have cavity, a number of methods have become known. The invention relates refer to such cones in which a valve body with pre-machined, approximately tulip-shaped Cavity is closed by a lid, and relates in particular to the implementation the weld.

Es ist bier-eits vorgeschlagen worden, derartige Ventile durch Nahtschweißung herzustellen, und man hat weiter angeregt, einen Ventilboden mit Hilfe der elektrischen Stumpfsch-weißung mit dem Ventilkörper zu verbinden. Dabei kann das Kühlmittel, wie Natrium, vor oder nach dem Verbindungsvo,rgang eingebracht werden. Nach der Erfindung wird nun die Schweißung entweder mit Hilfe des elektrischen Stumpfschweißverfahrens oder mit elektrischer Widerstandsschweiß-ung durchgeführt, wobei an der Schweiß-fuge eine besondere Legierung zur Erzielung einer besseren Verbindung eingebracht wird. Dabei ist es wichtig, daß der Schmelzpunkt dieser Legierung niedriger ist als der der zu verbindenden Teile; zweckmäßig liegt der Schmelzpunkt im Erweichungsge#biet des zu verschweißenden Stahles. Die Legierung muß weiter so beschaffen sein., daß sie in die Grundmasse, des Stahles gut eindiffundieren kann.It has already been proposed to weld such valves by seam welding and it has been suggested that a valve base should be made with the help of the electrical To connect butt weld with the valve body. The coolant, such as sodium, can be introduced before or after the connection process. After Invention is now the welding either with the help of the electric butt welding process or carried out with electrical resistance welding, whereby at the welding joint a special alloy is introduced to achieve a better connection. It is important that the melting point of this alloy is lower than that the parts to be connected; the melting point is expediently in the softening range of the steel to be welded. The alloy must continue to be such that it can diffuse well into the basic mass of the steel.

Dies kann erreicht werden durcl-1 eine Bindelegierung, die vorwiegend aus Mangan besteht und daneben noch andere Metalle, wie Kobaft, Nickel und Eisen, enthält. Eine bewährte Legierung bestand z. B. aus 64,6 1/o Nickel, 27,8 0/0- Mangan, Rest Eisen mit den.Üblichen Begleifern.This can be achieved by using a binding alloy that consists primarily of manganese and also contains other metals such as cobaft, nickel and iron. A proven alloy was z. B. from 64.6 1 / o nickel, 27.8 0/0 manganese, remainder iron with the usual companions.

Zur Durchführung des. Verfahrens wird diese Legierung an der Schweißfuge durch Aufbringen eines Pulvers oder einer Blechbeilage oder im Plattierwege aufgebracht. Danacli kann die Verschweißung durch elektrisches Stumpfschweißen oder durch Widerstandserhitzung, selbstverständlich aiber auch durch jedes andere entsprechende Ver,fahren,bewirkt weriden.To carry out the process, this alloy is applied to the weld joint by applying a powder or a sheet metal insert or applied in the plating way. Danacli can weld by electric butt welding or by resistance heating, of course also by any other corresponding process weriden.

Um einen einwandfreien Schweißvorgang zu sichern, empfiehlt es sich, die SchweißfUge außen vorher gegen Luftzutritt zu schützen.To ensure a perfect welding process, it is advisable to to protect the welding joint on the outside beforehand against the ingress of air.
