ABSTRACT:
Sampling devices for molten metal are known that consist of at least two cup-shaped, metallic components, which are arranged in such a way that their front (mating) surfaces face each other. These components form a sampling chamber, and they have an inlet pipe extending into the chamber. In order to construct a sampling device in a way that makes it quick and easy to remove the sample after the fluid metal has solidified, the chamber is coated with a wear-resistant layer which is temperature-stable up to approximately 1700.degree. C. This layer should be applied at least in the area of the orifice and the wall area opposite the orifice. The front surfaces of the cup-shaped components can remain uncoated.
