A container for molten metal includes an outlet for outflow of the molten metal from the container and a temperature measuring device fixed in a wall of the container. The temperature measuring device includes a plug, an outer protective sheath having a closed end, and an inner protective tube having a closed end. The inner protective tube is arranged within the outer protective sheath. A thermocouple is arranged within the inner protective tube. The plug includes a substantially refractory material and the outer protective sheath consists essentially of substantially refractory metal oxide and graphite. The outer protective sheath extends away from the first end of the plug and projects into a recessed portion of the wall of the container. The closed end of the outer protective sheath is arranged in the recessed portion. A junction of the thermocouple is proximate to the closed end of the inner protective tube. |
