| 摘要 |
<p>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 apparatus is characterised in that the inner cavity outer opening (6) is adapted to receive fixedly the optical pyrometer (7). Thereby, the accuracy and reproducibility of the measure is greatly increased. <IMAGE></p> |
