    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 achieved by providing the sampling container with openings which are closed and exposed by the valve means or by some other suitable arrangement.

    Abstract: Apparatus capable of being immersed into a molten steel bath to obtain the temperature of the bath and the carbon content of a sample thereof. The apparatus is a hollow receptacle having a cavity capable of retaining and cooling a steel sample. The cavity contains a thermocouple which records the cooling characteristics of the steel sample and especially the liquidus arrest temperature corresponding to a phase transformation of the sample. The liquidus arrest temperature is used as a measure of the carbon content of the steel bath. A second thermocouple may be used to record the bath temperature directly. Also described are processes for controlling various steelmaking and refining processes, especially the basic oxygen steelmaking process.
