Definitions

  • a fundamental problem when casting castings from a molten metal is to perform the mold filling with the molten material so that it comes as little as possible air and Oxidein whyn in the casting.
  • a particular course of solidification is sought in order to achieve a structure formation which satisfies the respective requirements for the distribution of the mechanical properties.
  • the mold is pivoted with the arranged on her tundish about the pivot axis in a pivoting direction, in which as a result of the pivoting and the

Abstract

Pour couler des pièces dans une machine de coulée (G), on fait pivoter un moule (5) sur un axe de pivotement horizontal (HS). Le moule (5) comporte un couvercle (9) pourvu d'un orifice de remplissage (13) et une paroi latérale de référence (7). Un niveau principal (HE), s'étendant parallèlement à l'axe de pivotement (HS), est placé dans la paroi latérale de référence (7). Un panier de coulée (15) est fixé au moule (5) et le moule (5) est ensuite pivoté dans une position de coulée dans laquelle le niveau principal (HE) de la paroi latérale de référence (7) forme, avec le niveau du bain (BS) d'une partie (S) du métal en fusion à remplir dans le panier de coulée (15), un angle β1 qui est inférieur à 180°, et le niveau du bain (BS) de la partie (S) de métal en fusion est situé en dessous de l'orifice de remplissage (13) du moule (5). Le panier de coulée (15) rempli d'une partie (S) de métal en fusion est pivoté avec le moule sur l'axe de pivotement (HS) de sorte que le métal en fusion (S) s'écoule dans le moule de coulée (5). L'angle β1, formé entre le niveau principal (HE) de la paroi latérale de référence (7) et le niveau du bain (BS) de la partie de métal en fusion (S) dans le panier de coulée (15), est toujours < 180° jusqu'à ce que la matière en fusion touche le fond (6) du moule (5).
