Description
Gußeisen für Hohlkörper Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Hohlkörpern, insbesondere von Hoh#lkö#rpern#, mit geringer Wandistärke, in eisernen Dauerforrnen unter Vemendung eines Hohldornesr.Cast iron for hollow bodies The invention relates to a method for the production of hollow bodies, especially hollow bodies, with low wall thickness, in permanent iron molds using a hollow mandrel.
Es Isti bekannt, Röhren und Hohlkörper aus Stahl, Kupfer und seinen Legierungen unter Verwendung von, Hohlidiornen int eisernen Formen (Kokillien) herzustellen. Auch hat, man vorgeschlagen, den Hob#1,d#orn(zus,ätzliich zu kühlen. Die Verwcn#ditiinig eines Hohldornes, bzw. seine zusätzliche Kühlung versaggen aber, wenn es sich darum handelt, Hoh-lkörper aus. Gußeisen herzustellen-. Dieses hersagen beruht darauf, daß Gußeisen praktisch: keine- Debnung hesitzt.It is known to have tubes and hollow bodies made of steel, copper and its Alloys are produced using hollow cores in iron molds (chill molds). It has also been suggested to cool the hob # 1, d # orn (additional, caustic a hollow mandrel or its additional cooling fail when it comes to it acts, hollow bodies out. Manufacture cast iron. This saying is based on that cast iron practically: no debudging.
Gemäß der Erfindung gelingt es, auch gußeiserne Hohlkörper unter Verivendung von: ei'sernen' Formen, und eines HohIdornes herzus--tellen!, wenn als Gußeisen die als Haeinatiteisen bekannte Eisensortei gewählt wird. Die- praktische- Durchführung der Erfindung hat gezeigte daß sogar Büchsen aus Haematiteisen mit einer Wandstärke von nur iSmm hersteIlhar sind. Das Ge-füge der so hergestellten HohIkörper fst feingraphitisch und, von mäßiger Härte. Die Wandstärke des Hohldornes ist, der Dicke de#s Gußstückes anzupassen.According to the invention, it is also possible to use hollow cast iron bodies of 'iron' forms, and to produce a hollow mandrel! if as cast iron the type of iron known as Haeinati iron is selected. The practical implementation the invention has shown that even sleeves made of Haematiteisen with a wall thickness are manufactured from only iSmm. The structure of the hollow bodies produced in this way is almost finely graphical and, of moderate hardness. The wall thickness of the hollow mandrel is the thickness of the casting adapt.
