Abstract

A radiation thermometer for measurement of the temperature of molten iron includes a probe tube with a sealed bottom in the form of a spheroidal shape and is made of zirconium boride ceramics. The probe tube is immersed in molten iron and radiation emitted from the spheroidal closed end of the probe tube is received by a sensor at the far end of the tube which is above the level of the molten iron. The spheroidal end of the probe tube is below the surface of molten iron by more than 10 times the inner radius of the probe tube.
