Description
Die Herstellung von Verbundblöcken erfolgte bisher meistens durch Zusammengießen von zwei verschiedenen Werkstoffen, z. B. Stahl, Eisen oder Metallen, soweit sie innerhalb ihrer Zusammensetzung eine Verschweißung bzw. innige Verbindung in flüssigem Zustande zulassen.The production of composite blocks has so far mostly been carried out by Casting together of two different materials, e.g. B. steel, iron or metals, insofar as they form a weld or an intimate connection within their composition allow in the liquid state.
Es mußten deshalb zwei Schmelzöfen hierfür an der Erzeugungsstätte der Verbundblöcke zur Verfügung stehen.Therefore two smelting furnaces had to be installed at the production site the composite blocks are available.
Durch die Erfindung wird die Herstellung von Verbundblöcken durch die Verwendung von nur einem Schmelzofen ermöglicht. In der Zeichnung ist der Arbeitsgang schematisch dargestellt.The invention enables the production of composite blocks allows the use of only one melting furnace. In the drawing is the operation shown schematically.
Aus einem so weit als zuträglich hocherhitzten massiven Block wird in bekannter Weise in einer Matrize durch Lochen auf einer Presse ein Hohlkörper i ähnlich Abb. i hergestellt.From a massive block heated up to the point that it is beneficial a hollow body in a known manner in a die by punching on a press i manufactured similar to Fig. i.
Sofort nach dem Herausziehen des Lochdornes aus dem Hohlkörper wird zweckmäßig mit einem Löffel ein geringes Quantum Kohle, Borax oder ein sonst geeignetes Produkt auf den Boden des Hohlkörpers geschüttet, welches infolge der großen Hitze sofort Gase entwickelt, welche den Innenraum ausfüllen und eine Oxydation der Innenwand des Hohlkörpers verhindert.Immediately after pulling the piercer out of the hollow body It is advisable to use a spoon to add a small amount of charcoal, borax or some other suitable solution Product poured on the bottom of the hollow body, which as a result of the great heat Immediately developed gases, which fill the interior and an oxidation of the inner wall of the hollow body prevented.
Auf den aus der Lochmatrize herausgenommenen und noch sehr hoch erhitzten Hohlkörper wird nun, wie in Abb. 2 dargestellt. in schneller Reihenfolge ein Trichter 2 aufgesetzt und sofort anschließend durch diesen der Hohlkörper und Trichter bis an den oberen Rand mit flüssigem Werkstoff 3 gefüllt.On the one taken out of the perforated die and still heated to a very high temperature Hollow body is now as shown in Fig. 2. in quick succession a funnel 2 put on and immediately afterwards through this the hollow body and funnel up to filled with liquid material 3 at the upper edge.
Während des Gießens fügt man dem flüssigen Werkstoff etwas wärmeentwickelnde Masse, Termit o. dgl., zu, wodurch die Temperatur des eingegossenen Werkstoffes 3 in dem Hohlkörper erhöht und das Zusammenschmelzen bzw. innige Verbinden der beiden Werkstoffe i und 3 gefördert wird.During the pouring process, something that generates heat is added to the liquid material Mass, termite or the like, too, whereby the temperature of the poured material 3 increased in the hollow body and the melting together or intimate connection of the two Materials i and 3 is promoted.
Möglichst sofort nach derErstarrung des inneren `'Werkstoffes wird der verlorene Kopf des entstandenen Verbundblockes entfernt, so daß der Block nunmehr wie in Abb. 3 dargestellt aussieht.As soon as possible after the solidification of the inner '' material the lost head of the resulting composite block is removed so that the block is now looks like shown in Fig. 3.
Der Verbundblock kann anschließend, also noch in warmem Zustande, einem Wärmeofen zugeführt werden, wo die Hitze der beiden Werkstoffe ausgeglichen bzw. der Verbundblock auf die erforderliche Temperatur gebracht wird, um dann im Walzwerk oder unter dem Hammer zu Stäben oder sonstigen Profilen verarbeitet zii werden.The composite block can then, while still warm, fed to a heating furnace, where the heat of the two materials is balanced or the composite block is brought to the required temperature, then in Rolling mill or under the hammer processed into bars or other profiles zii will.
Der aus dem Wärmeofen kommende Verbundblock kann außerdem mit einem wie über der Abb. 3 dargestellten Lochdorn .4 in einer Matrize in bekannter `'eise oder aber auf eine andere bekannte Art (Schrägwalzwerk) gelocht werden, wodurch ein Verbundhohlkörper ähnlich Abb. 4 entsteht.The composite block coming out of the heating furnace can also be connected to a as shown in Fig. 3 piercing mandrel .4 in a die in the known `` 'iron or punched in another known way (cross rolling mill), whereby a composite hollow body similar to Fig. 4 is created.
Der Verbundhohlkörper kann zur Weiterverarbeitung zu nahtlosen plattierten Rohren, Stahlflaschen und anderen Hohlkörpern dienen.The composite hollow body can be clad for further processing into seamless Pipes, steel bottles and other hollow bodies are used.
