摘要:
Disclosed is a system and method for evaluating a status of a refractory material in metallurgical vessels, including furnaces and ladles, wherein a slag buildup is formed on the surface of such material as a result of scrap accumulation and chemical reactions occurring during the melting of metals in such vessels. The system and method are operative to determine both a rate of degradation of the material under evaluation, including the thickness of such material, and a measure of the slag buildup to predict and extend the operational life and improve the maintenance plan of the vessel. The system is capable of determining the thickness of and the slag buildup on the entire material under evaluation by sampling a number of regions of such material with different types of sensors, characterizing the surface profile of such material, and using appropriate signal processing techniques and artificial intelligence algorithms.

Disclosed is an apparatus and method for evaluating a status of a refractory material in metallurgical vessels, including furnaces and ladles, wherein an external structure at least partly surrounding the refractory material impairs the propagation of radiofrequency signals. The apparatus and method are operative to identify flaws and determine the erosion profile and thickness of refractory material and the level or rate of penetration of molten material into the refractory material, using radiofrequency signals. The apparatus comprises an antenna embedded in the refractory material or positioned inside the chamber of the vessel designed to collect data associated with the propagation of radiofrequency signals transmitted by the antenna into the refractory material. Moreover, signal processing techniques allow determining the status of the internal wall of the vessel due to operational wear, age, and presence of flaws, cracks, corrosion, and erosion to improve the operational life and maintenance of the vessel.
