CHILL MOULD FOR THE CASTING OF LIGHT METAL CASTING MATERIALS, AND THE USE OF SUCH A MOULD, AS WELL AS OF A CAST IRON MATERIAL

摘要

The invention relates to a chill mould for the casting of light metal casting materials, manufactured from an Ni- alloyed and/or Mn alloyed cast iron material, of which the Ni and/or Mn content is dimensioned in such a way that the thermal coefficient of expansion of the chill mould is adjusted to the thermal coefficient of expansion of the light metal casting material which is to be cast in each case. By means of the invention a chill mould is provided which can be manufactured in an economical manner which possesses optimised properties of use and at the same time allows for optimised casting results. Such a chill mould is accordingly well-suited in particular as a constituent part of a sand casting mould for the casting of a cylinder block (1) from a light metal casting material.
