摘要： The invention provides an apparatus for measuring the temperature of a molten bath comprising a) a refractory mounting sleeve ( 1,1') having an outer surface (2) for contacting the molten bath and an inner cavity (3), said inner cavity having an inner surface (4), an outer opening (6) and an inner closed end (5); and b) an optical pyrometer (7) attached to the mounting sleeve and adapted to measure the thermal radiation emitted by a measurement zone (10) located inside the inner cavity of the mounting sleeve and under the molten bath level. The inner cavity outer opening (6) is adapted to receive fixedly the optical pyrometer (7). The apparatus is characterized in that the mounting plate (8) is adapted to engage in a complementary recess located at the inner cavity outer opening (6) of the mounting sleeve (1,1'). Thereby, the accuracy and reproducibility of the measure is greatly increased.

摘要： The invention describes a submerged sensor for use in a metallurgical vessel, such as a tundish. The sensor is positioned so that in use it is below a surface of a molten metal bath within the vessel. The sensor conveniently extends through the vessel wall and projects into the volume of the vessel. An upper end of the sensor is encased in a protective assembly. The protective assembly of the invention can be shaped so as to control the pattern of molten metal flow in the vessel or measure more accurately the molten metal exiting the vessel. Advantageously, the invention can combine the functionality required for flow pattern modification such as provided by a dam, impact pad or baffle, with the functionality required for a sensor. This combination reduces cost and complexity.
