Description
Verfahren zur Herstellung von Gußblöcken mit verschieden harten und rostfesten Schichten. Es sind bereits Verfahren bekannt, verschiedene Eisensorten in einer Gußform derart zu einem fest verbundenen Gußkörper zu vergießen, daß eine Mischung :der Sorten untereinander vermieden wird. Das wird in verschiedener Weise erreicht. Zur Trennung der verschiedenen Eisensorten werden geschlossene Taschen-oder Schneidewände aus Blechen oder Platten in die Gußform eingeführt, die auch, wie es vorgeschlagen ist, gebeizt und mit einer Mischung von Borax und Ammoniak oder ähnlich wirkenden Salzen versehen sein können, um eine bessere Verbindung mit dem flüssigen Eisen zu erlangen. Diese Verfahren haben den Nachteil, daß verschiedene Eisensorten zur gleichen Zeit gußbereit sein müssen. Da die. Blockgüsse in einem Stahlwerk aber aus einer großen Gießpfanne hintereinander abgegossen wenden müssen, wofür nur immer ein Krahn oder ein Gießwagen zur Verfügung steht, so ist die Durchführung der- bekannten Verfahren im Stahlwerksbetrieb ' nicht angängig oder wenigstens schwierig und für die Leistung nachteilig: Das Vergießen mehrerer Blöcke in einem Gespann mit Bodeneinläufen wäre damit nicht zu ermöglichen. Es ist auch vorgeschlagen worden, in Blöckformen Eisen um einen Eisenkern zu 'vergießen, der durch eine Hülle von Graphit, Ton u: dgl. den Kern von dem eingeossenen Mantel trennen und'Blasenbildung verhüten soll. Das würde sich aber, abgesehen von der Trennung von Mantel und Kern, wegen -der mehrfachen Lunkerbildung verbieten. Um diese Übelstände zu beseitigen und das Verfahren brauchbar zuestalte@n,. soll nur eine Eisensorte vergossen, und durch Zuschläge in einzelne Kammern der Gußformen die gewünschte Trennung nach verschiedenen Eisenlegierungen im Einzelblock erreicht werden.Process for the production of ingots with different hardness and anti-corrosive layers. Processes are already known, various types of iron to cast in a mold in such a way to form a firmly connected cast body that a Mixture: the varieties are avoided among each other. That will be done in different ways achieved. To separate the different types of iron are closed pockets or Cutting walls made of sheets or plates introduced into the mold, which also, like it is suggested pickled and coated with a mixture of borax and or ammonia similar acting salts may be provided to better connect with the to obtain liquid iron. These methods have the disadvantage that different Types of iron must be ready for casting at the same time. Since the. Block casts in one Steelworks, however, have to turn poured from a large ladle one after the other, what is only ever a crane or a watering wagon is the implementation the known method in steel mills' not accessible or at least difficult and disadvantageous for the performance: The casting of several blocks in a team with floor drains would therefore not be possible. It has also been suggested iron in block molds to 'cast an iron core through a shell of Graphite, clay and the like separate the core from the cast-in jacket and bubble formation should prevent. But apart from the separation of shell and core, that would forbid because of the multiple formation of cavities. To remedy these evils and to make the process usable. should only cast one type of iron, and the desired separation according to different types by adding to the individual chambers of the casting molds Iron alloys can be achieved in a single block.
Zu dem Zwecke werden in -den Gußformen ,durch eingelegte, gegen die Gußform gepreßte dünne Bleche in bekannter Weise Kammern hergestellt, von denen ein Teil mit besonderen Härtemitteln, wie Eisenmangan-und -siliziumverbindungen, Chromnickel und ähnlichen, die zwsichen lockeren und sperrigen Eisenteilchen, etwa geglühten Drehspänen, gebettet sein können, angefüllt sind. Zur Vermeidung -schädlicher Gasbildung kann Aluminium, rein oder in Legierungen, und als Rostschutzmittel Nickel, Kupfer oder ähnlicher Zusatz beigegeben werden. Zur Wärmesteigerung zum -Zwecke besserer Verschmelzung -der Eisenteile und der eingelegten Bleche kann noch Termit hinzugefügt werden.For this purpose, the molds are inlaid against the Mold pressed thin sheets are made in a known manner, chambers of which a part with special hardening agents, such as iron manganese and silicon compounds, Chrome nickel and the like, the between loose and bulky iron particles, for example annealed turnings, can be bedded, are filled. To avoid harmful Gas formation can be aluminum, pure or in alloys, and as a rust preventive nickel, Copper or a similar additive can be added. To increase heat for purposes Better amalgamation of the iron parts and the inserted metal sheets can still be termite to be added.
Man füllt nun .die Gußform mit dein flüssigen Eisen in der Weise, daß das Eisen in die freien Kammern läuft, wobei es an den eingeschobenen dünnen Blechen zunächst erstarren wird.The mold is then filled with your liquid iron in the manner that the iron runs into the free chambers, with it on the inserted thin ones Sheet metal will initially solidify.
In den Blechen sind oben reichlich große Überlauföffnungen angebracht,
durch welche das flüssige Eisen, wenn die Blockhöhe ungefähr erreicht ist, in die
mit. den Zuschlägen versehenen Kammern überläuft und beim Steigen die eingeschobenen
Trennungsblecbe zum Schmelzen bringt und sich auch mit dem an den Trennungsblechen
bereits erstarrten Eisen verschmelzen wird.
Auf diese Weise werden
Gase, die sich beine Auflösen der Zuschläge im flüssigen Eisen bilden könnten, sich
