Abstract

EL NIVEL DE LA SUPERFICIE DE UN BAÑO DE METAL FUNDIDO DEBAJO DE UNA CAPA DE ESCORIA FLUIDA EN UN RECIPIENTE METALURGICO SE MIDE MEDIANTE UN DETECTOR QUE SE MUEVE A TRAVES DE LA CAPA DE ESCORIA EN EL BAÑO METALICO Y LUEGO SE EXTRAE. PARA MEJORAR LA EXACTITUD Y PARA EVITAR LA NECESIDAD DE UNA MEDIDA SEPARADA, EL DETECTOR USADO CONTIENE UN SENSOR DE CONCENTRACION DE OXIGENO, QUE EMITE SEÑALES QUE INDICAN EL LIMITE ENTRE EL METAL FUNDIDO Y LA ESCORIA, CON LO QUE SE DETERMINA LA ALTURA DE DICHO LIMITE.
