Abstract

LANZA METALURGICA. CONSTITUIDA POR UN ELEMENTO TUBULAR METALICO (2) ENCAPSULADO EN UN MANGUITO (3) DE MATERIAL REFRACTARIO, EN EL QUE ESTAN DISPUESTOS UNA PLURALIDAD DE REFUERZOS LONGITUDINALES (4) SUJETOS AL TUBO (2) POR ELEMENTOS SEPARADORES (5). LOS ELEMENTOS DE REFUERZO (4) SE CONECTAN ENTRE SI DOS A DOS POR SUS EXTREMOS INFERIORES Y ESTAN REALIZADOS POR PERFILES DE SECCION CIRCULAR, MACIZOS O TUBULARES; SI SON TUBULARES SE PUEDEN CONECTAR A UNA ALIMENTACION EXTERIOR PARA PERMITIR EL PASO DE UN FLUIDO REFRIGERANTE. UNA ESTRUCTURA PERFORADA (6) RODEA LOS ELEMENTOS DE REFUERZO, QUE JUNTO CON EL TUBO (2) SE RECUBREN CON UN COMPUESTO DE BAJO PUNTO DE FUSION QUE SE ELIMINA AL COCER LA LANZA DEJANDO UN ESPACIO DE SEPARACION ENTRE TUBO (2), ELEMENTOS DE REFUERZO (4) Y MATERIAL REFRACTARIO (3).
