Abstract
An immersion molten metal sampling device of a type usable to obtain a sample of molten steel from a furnace and to measure the temperature of the molten metal in the furnace. The device includes a high density monolithic ceramic mold capable of obtaining a flat, rectangular shaped sample of the molten metal for spectrographic analysis as well as a pin sample for combustion analysis. The construction of the sampler avoids contamination of the sample by using gas permeable substances that are gaseous inert at the temperature of the molten metal while at the same time eliminating problems due to leakage of the molten metal through vent passages and seams in the mold.
