Abstract

L'invention porte sur un procédé et un dispositif permettant de prélever un matériau de coulage, sans l'endommager, d'un moule en sable vert coulé de métal fondu. Ce procédé de séparation d'un matériau de coulage d'un moule en sable vert coulé consiste à transporter vers l'intérieur des moules en sable vert coulé supérieur et inférieur d'une ligne de coulée de matériau à un emplacement spécifique, enfermer de manière hermétique dans une chambre au moins un des moules supérieur et inférieur à l'emplacement spécifique et placer le matériau de coulage dans un des moules, mettre sous pression la chambre afin de réduire le point d'ébullition de l'eau dans une couche de condensation d'eau dans au moins un des moules et porter l'eau à ébullition dans la couche de condensation d'eau, et briser le moule en sable vert pour le séparer du matériau de coulage.
