ABSTRACT:
A method for measuring the temperature of a metallurgical furnace. An empirical relationship is established that connects the temperature, an operating parameter of the furnace that is causally connected with the generation of acoustic noise, and a representative acoustic noise frequency. Preferably, the relationship is based on modeling the gas phase in the furnace as an ideal gas; the representative frequency is the centroid frequency of the acoustic noise spectrum; and the empirical relationship includes the transformation of the operating parameter into an effective acoustic noise wavelength.
