Abstract

EL DISPOSITIVO DE INYECCION DE AIRE PRECALENTADO EN UN HORNO DE CUBA SE COMPONE DE VARIOS ELEMENTOS TUBULARES PROVISTOS DE UN REVESTIMIENTO REFRACTARIO QUE ESTAN CONECTADOS, ENTRE SI, POR UNA ARTICULACION ESFERICA (94, 96) Y UN COMPENSADOR. LAS ARTICULACIONES ESFERICAS ESTAN FORMADAS POR UNA ROTULA CONVEXA FORMADA EN UN SEGMENTO Y POR UN PLATILLO CONCAVO FORMADO EN EL REFRACTORIO DEL SEGMENTO ADYACENTE. COMPRENDEN UNA VAINA DE PROTECCION DE ACERO REFRACTARIO QUE SE EXTIENDE ALREDEDOR DE LA PARTE CONVEXA HASTA LA BASE DE LA ROTULA. EL RADIO DE CURVATURA DE CADA ARTICULACION ESFERICA ES DEL TAMAÑO DE LA MITAD DEL DIAMETRO DE LOS ELEMENTOS TUBULARES.
