[Resumen del autor]
The here published work represents a final study project required to obtain the degree in process and energy engineering at the Technische Universitát Berlín, Germany. It was realized within an investigation project between the Departamento de Física at the University Federico Santa María in Valparaíso, Chile, and the government owned enterprise Codelco. The theoretical and experimental parts of the work were carried out at the laboratories of the Applied Physics Department; furthermore measurements of the Teniente Copper Converter were realized at the smelting plant of the Chuquicamata Mine at Calama, Chile. Objective oí the work was the design of an automated measurement system for metal bath levéis inside metallurgical converter ovens. Central part of the highly innovative system is the application of infrared thermography in order to analyse the exterior temperature distribution, and gain conclusions in respect to the positions of interior phase boundaries.
