ABSTRACT:
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.
