Continuous temperature measuring probe and continuous temperature measuring apparatus of molten metal

摘要

To provide a continuous temperature measurement probe of molten metal and continuous temperature measurement device capable of continuously measuring correct temperature of molten metal.SOLUTION: A continuous temperature measurement probe 1 of molten metal includes a radiation thermometer 3 that is arranged in a rear end part of a protective tube 2 where a tip end part is closed. In the continuous temperature measurement probe 1, the protective tube 2 is formed of a carbon-containing refractory product that does not contain silicon carbide. Besides, a continuous temperature measurement device of molten metal includes the continuous temperature measurement probe 1. The continuous temperature measurement probe 1 of molten metal and the continuous measurement device are suitable to measure temperature of molten metal in a continuous casting facility such as tundish.SELECTED DRAWING: Figure 1
