Description
SPHAROGUSS MIT HOHER FESTIGKEIT UND DUKTILITAT UND DARAUS HERGESTELLTES GETRIEBEGEHAUSE 5SPHAROGOUS WITH HIGH STRENGTH AND DUCTILITY AND GEARBOX MANUFACTURED THEREOF 5
Die Erfindung betrifft einen Sphäroguss mit einlegiertem Silizium, wie er für stark beanspruchte Gussteile üblicherweise verwendet wird, beispielsweise die Werkstoffe nach DIN beziehungsweise SAE [in eckiger Klam- 0 mer]:The invention relates to a nodular cast iron with siliconized silicon, as it is commonly used for heavily used castings, for example the materials according to DIN or SAE [in square brackets]:
a) EN-GJS-400-16 [D4018], b) EN-GJS-500- 7 [D4512], c) EN-GJS-600- 3 [D5608], 5 d) EN-GJS-700- 2 [D7003].a) EN-GJS-400-16 [D4018], b) EN-GJS-500-7 [D4512], c) EN-GJS-600-3 [D5608], 5d) EN-GJS-700-2 [ D7003].
Von diesen ist der erste (a)) noch ferritisch und daher zähe, aber seine Festigkeit ist nur mittelmäßig. Soll die Festigkeit höher sein, greift man zu den Werkstoffen b), c) und d), die der Reihe nach ferritisch-perlitisch bis 0 rein perlitiscli sind, bei stark abnelimender Zähigkeit und Schweissbarkeit. Diese Werkstoffe weisen in von a) bis zu d) zunehmendem Maße ein mehrphasiges (ferritisch-perlitisches) Grundgefuge örtlich verschiedener Zusammensetzung auf, was durch die beim Giessen unvermeidlichen örtlich verschiedenen Abkühlbedingungen noch verstärkt wird und zu Pro- 5 blemen bei der nachfolgenden, insbesondere zerspanenden, Bearbeitung führt. Deren Einsatz ist daher auf besondere Anwendungen beschränkt.
Im Fahrzeugbau ist die Verringerung des Gewichtes ein besonderes Anliegen, was bei Gussteilen geringe Wandstärken - also hohe Festigkeit - aber auch Zähigkeit sowie gute Bearbeitbarkeit erfordert. Man ist dann genötigt, Stahl einzusetzen, der aber um etwa 10 Prozent schwerer ist.Of these, the first one (a) is still ferritic and therefore tenacious, but its strength is only mediocre. If the strength is to be higher, one resorts to the materials b), c) and d), which in turn are ferritic-perlitic to 0 perlitiscli, with strong declinative toughness and weldability. These materials have from a) to d) increasingly a multiphase (ferritic-pearlitic) Grundfuge locally different composition, which is reinforced by the unavoidable during casting locally different cooling conditions and to 5 problems in the subsequent, in particular machining , Editing leads. Their use is therefore limited to special applications. In vehicle construction, the reduction of weight is a particular concern, which in castings low wall thickness - ie high strength - but also requires toughness and good workability. It is then necessary to use steel, but it is about 10 percent heavier.
Zwar ist es bekannt, im Fahrzeugbau für Anwendungen, die eine hohe Hitzebeständigkeit erfordern, Sphäroguss mit hohem Gehalt an Silizium und 0,5 bis 2 Prozent Molybdän einzusetzen. Dieser ist jedoch sehr spröde und überhaupt schwer bearbeitbar.Although it is known in automotive applications for applications that require high heat resistance, to use nodular cast iron with a high content of silicon and 0.5 to 2 percent molybdenum. However, this is very brittle and difficult to work at all.
Es ist somit Aufgabe der Erfindung, Sphäroguss so zu verbessern, dass er trotz hoher Festigkeit zäh, gut bearbeitbar und schweissbar ist.It is therefore an object of the invention to improve nodular cast iron so that it is tough, easy to machine and weld despite high strength.
Ein erfindungsgemäßer Sphäroguss enthält: 4 bis 6 Prozent Silizium und einen entsprechend dem Kohlenstoffäquivalent verringerten Anteil an Kohlenstoff, maximal 0,03 Prozent Phosphor und 0,2 bis 0,5 Prozent Nickel. Der hohe Gehalt an Silizium wirkt Ferrit - stabilisierend und erhöht auch die Festigkeit. Das Kohlenstoffäquivalent erfordert eine entsprechende Absenkung des Kohlenstoffgehaltes. Da Phosphor aufgrund der starken Mischkristallverfestigung der mit von ihm eingegangenen Verbindungen versprödend wirkt, ist der Phosphorgehalt möglichst klein zu halten. Auch Nickel verringert die Sprödigkeit und vergrößert die Festigkeit, wobei die erforderlichen Anteile so gering sind, dass die dadurch entstehenden Mehrkosten vemachlässigbar sind.A nodular cast iron according to the invention contains: 4 to 6 percent silicon and a proportion of carbon corresponding to the carbon equivalent, a maximum of 0.03 percent phosphorus and 0.2 to 0.5 percent nickel. The high content of silicon has a ferrite-stabilizing effect and also increases the strength. The carbon equivalent requires a corresponding reduction of the carbon content. Since phosphorus acts as embrittlement due to the strong solid solution hardening of the compounds it has received, the phosphorus content must be kept as small as possible. Nickel also reduces the brittleness and increases the strength, the required proportions are so small that the resulting additional costs are negligible.
Die Festigkeit wird hier nicht, wie bei Sphäroguss nach dem Stand der Technik, über einen höheren Gehalt an Perlit erhalten, sondern durch Mischkristallverfestigung. Im Zusammenwirken dieser Maßnahmen wird
eine deutliche Festigkeitssteigerung bei guter Duktilität und Schweissbarkeit erreicht.The strength is not obtained here, as in nodular cast iron according to the prior art, via a higher content of perlite, but by solid solution hardening. The interaction of these measures will achieved a significant increase in strength with good ductility and weldability.
Die Mengenverhältnisse, bei denen besonders gute Werte erzielt wurden sind gemäß Ansprüchen 2 und 3 Silizium bei 4,1 bis 4,5 Prozent und Nickel bei 0,25 bis 0,35 Prozent. Die Begrenzung des Gehaltes an Kupfer unter das übliche Maß verstärkt die Wirkung der erfindungsgemäßen Maßnahmen, da Kupfer ein Perlitbildner ist.The proportions at which particularly good values have been achieved according to claims 2 and 3 silicon at 4.1 to 4.5 percent and nickel at 0.25 to 0.35 percent. The limitation of the content of copper below the usual level enhances the effect of the measures according to the invention, since copper is a perlite former.
Schließlich betrifft die Erfindung auch Gehäuse, insbesondere Getriebe- gehäuse, die aus einem Sphäroguss nach einem der vorhergehenden Ansprüche bestehen. Ein solches Getriebegehäuse kann wegen der hohen Festigkeit des erfindungs gemäß verbesserten Sphäroguss dünnwandiger und leichter sein. Die für die Bildung von Anschlussflanschen und Lager- sitzen nötige spanabhebende Bearbeitung ist uneingeschränkt möglich.Finally, the invention also relates to housings, in particular gear housing, which consist of a ductile iron according to one of the preceding claims. Such a gear housing can be thinner walled and lighter because of the high strength of the fiction, according to improved ductile iron. The machining necessary for the formation of connection flanges and bearing seats is possible without restriction.
Weiters kann ein Getriebegehäuse aus dem erfindungsgemäßen Werkstoff mit einem Verzahnungsteil aus legiertem und/oder einsatzgehärtetem Stahl verschweisst sein.Furthermore, a gear housing made of the material according to the invention can be welded to a toothed part made of alloyed and / or case-hardened steel.
