A sampling device for molten metals with a sample chamber arranged in a paperboard tube has an inflow canal leading through the paperboard tube, the canal being formed essentially of a heat-resistant inflow tube, such that the outer end of the inflow tube ends below (inside) the outer circumference of the sampling device and is closed off by a delayed-action device. In order to create a sampling device in which the intrusion of contaminants into the sample chamber is prevented, especially slag particles, gas occlusion particles and particles of the paperboard tubes, the delayed- action device is constructed as a multi-layered cap, whereby between cap and paperboard tube an intermediate space is formed, which is filled with cement.
Échantillonneur de métal liquide comprenant une chambre d'échantillonnage aménagée dans un tube en carton. L'échantillonneur comprend un canal d'amenée passant dans le tube; ce canal est formé essentiellement d'un tube d'amenée résistant à la chaleur et conçu de telle sorte que son extrémité extérieure se termine sous (intérieur) la circonférence extérieure de l'échantillonneur et est fermée par un retardateur. Pour empêcher l'entrée de contaminants dans la chambre d'échantillonnage, en particulier l'entrée de particules de laitier, de particules d'occlusions de gaz et de particules de tube de carton, le retardateur de l'échantillonneur est conçu comme d'un bouchon à couches multiples, et entre ce bouchon et le tube se trouve un espace intermédiaire qui est rempli de ciment.
