Abstract

Bei einem Verfahren zum Herstellen eines Gussstücks, insbesondere eines Maschinenelements wie eines Zylinderblocks, aus graphithaltigem Gusseisen, werden erfindungsgemäß für unterschiedliche Beanspruchungszonen (4, 3) des Gussstücks unterschiedliche Graphitstrukturen enthaltende Gusseisenchargen und/oder Legierungen nacheinander in eine Form (2) gegossen, wodurch sich die Möglichkeit ergibt, die örtlichen Materialeigenschaften an den Beanspruchungsfall besser anzupassen als bei einer Herstellung aus einer einzigen homogenen Schmelze. Es wird auch eine zum Durchführen des Verfahrens besonders geeignete Vorrichtung beschrieben.

In a method for producing a casting, in particular a machine element such as a cylinder block from graphite-containing cast iron, according to the invention for different stress zones (4, 3) of the casting different cast iron batches containing graphite structures and / or alloys successively poured into a mold (2) gives the possibility to better adapt the local material properties to the load case as compared to a production of a single homogeneous melt. An apparatus which is particularly suitable for carrying out the method is also described.
