Abstract

Vorgeschlagen wird eine Vorrichtung zum Gießen von Gußeisen in einer Kokille mit einer mehrteiligen metallischen Kokille 1, die eine Sandform 3 umschließt, in deren Hohlraum 4 das geschmolzene Gußeisen eingefüllt wird.Proposed is a device for casting cast iron in a mold with a multi-part metallic mold 1, which encloses a sand mold 3, in the cavity 4, the molten cast iron is filled.

Zur Verbesserung nicht nur der Kühlung, sondern insbesondere auch der Steuerbarkeit der Kühlung ist erfindungsgemäß zwischen der Innenwand der Kokille und der Außenwand der Sandform wenigstens ein kühlmitteldurchströmter Raum 2 gebildet, der vorzugsweise die Form wenigstens eines zwischen einem Kühlmitteleintritt 5 und -austritt 8 verlaufenden Kanals hat und dabei jeweils etwa zur Hälfte gebildet ist durch eine rinnenartige Vertiefung der Innenwand der Kokille 1 und eine gegenüberliegende rinnenartige Vertiefung in der Außenwand der Sandform 3.In order to improve not only the cooling, but in particular the controllability of cooling, at least one coolant-flowed space 2 is formed between the inner wall of the mold and the outer wall of the sand mold, which preferably has the shape of at least one channel extending between a coolant inlet 5 and outlet 8 and in each case about half formed by a groove-like depression of the inner wall of the mold 1 and an opposite groove-like depression in the outer wall of the sand mold third

Die verbesserte Kühlung und Lenkbarkeit der Erstarrung des Gußteils ermöglicht die Erzielung optimaler, reproduzierbarer Material- und Gefügeeigenschaften.
