Abstract
An arrangement for use when thermally analyzing and modifying molten metal, by recording solidification data and controlling the structural modification of the molten metal on the basis of such data. The arrangement includes a sampling container made from a material which remains substantially stable at the temperature of the molten metal and which is adapted to receive at least one thermoelement for recording the solidification data. Means are also provided for taking a sample of the molten metal with the aid of the container, and for moving the sample to an area in which substantially the same conditions prevail. In addition, the arrangement includes recording means and means for modifying the structure of the molten metal as required. The sampling container is constructed to allow molten metal to pass thereinto when the container is immersed into the molten metal, and to allow a previous content of the container to be displaced therefrom and replaced with fresh molten metal as a result of relative movement between the container and the molten metal. Means are provided to ensure that a suitable quantity of molten metal is collected during a sampling operation. This may be achieve…
