Description

Verfahren zur Herstellung von Verbundgußkörpern Es sind bereits eine Reihe von Verfahren bekannt geworden, um aus verschiedenen Metallen einheitliche Körper, sogenannte Verbundgußkörper, herzustellen. So hat man galvanische und Walzverfahren für diesen Zweck angewendet, aber abgesehen davon, daß die Haftfähigkeit solcher Auflagen Mängel zeigt, war dieses Verfahren vielfach deshalb nicht sehr wirtschaftlich, weil, um überhaupt eine Bindung herbeizuführen, besondere Maßnahmen, wie Zwischenlagen besonderer Metalle und ähnliche Maßnahmen, erforderlich sind. Man hat auch versucht, mit Hilfe der Fliehkraft Verbundgußkörper herzustellen. Bei einer Gruppe derartiger Verfahren laufen die Gußformen um ihre eigene Mittelachse, während im Gegensatz hierzu das Gußverfahren nach dem Hauptpatent mit relativ zur Schleudervorrichtung stillstehenden Formen arbeitet. In anderen Fällen, bei denen die Formen auch relativ stillstehen, erfolgt im Gegensatz zum Verfahren des Hauptpatents der Einguß des Metalls in radialer Richtung zur Schleudervorrichtung. Der hauptsächlichste Unterschied der bekannten Verfahren gegenüber dem erfindungsgemäßen Verfahren besteht aber darin daß in allen bisher bekannten Verfahren die Formgebung nur durch die Größe der Fliehkraft und den Widerstand der Auflagekörper bedingt wird.Process for the production of composite castings There are already one A number of methods have become known to make uniform from different metals Body, so-called composite castings to produce. So you have galvanic and rolling processes applied for this purpose, but apart from the fact that the adhesiveness of such Shows deficiencies, this process was therefore often not very economical, because, in order to bring about a bond at all, special measures, such as intermediate layers special metals and similar measures are required. They also tried produce composite castings with the help of centrifugal force. With a group of those Processes run the molds around their own central axis while in opposition for this the casting process according to the main patent with relative to the centrifugal device stationary forms works. In other cases where the forms are also relative stand still, in contrast to the process of the main patent, the casting of the Metal in the radial direction to the spinner. The main difference the known method compared to the method according to the invention consists in this that in all previously known methods the shaping only by the size of the centrifugal force and the resistance of the support body is conditioned.

Nach dem Verfahren gemäß der Erfindung erfolgt die Aufschichtung innerhalb einer Form aber dergestalt, daß der mit dem anzugießenden Metall zu verbindende Körper einen Teil der Gußform bildet. Es hat sich überraschenderweise gezeigt, daß sich in dieser Weise eine Verbindung des Formgußverfahrens mit dem des Verbundgusses herbeiführen läßt. Der Vorteil besteht in der gleichmäßigen Ausbildung der Verbundmetallschichten sowohlhinsichtlich ihrer Stärke als auch ihrer sonstigen metallurgischen Eigenschaften.According to the method according to the invention, the stratification takes place within a shape but such that the to be connected with the metal to be cast on Body forms part of the mold. It has surprisingly been found that In this way, the molding process is combined with that of composite casting bring about. The advantage lies in the uniform formation of the composite metal layers both in terms of their strength and their other metallurgical properties.
