Abstract

LANZA PARA EL AFINO DE METALES POR SOPLADO DE OXIGENO POR ARRIBA, CUYA CABEZA PRESENTA POR ENCIMA DE LA EMBOCADURA (5) UNA TOBERA (1) QUE CONDUCE UN CHORRO DE GAS QUE ESTA COMPUESTO AL MENOS EN PARTE DE OXIGENO Y TENIENDO UNA VELOCIDAD SUPERSONICA. LA TOBERA (1) SE COMPONE DE UN TUBO INTERIOR (20) CUYA PARTE INFERIOR (21) ES CONVERGENTE Y DE UN TUBO ESTERIOR (3), COAXIAL AL TUBO INTERIOR Y QUE TIENE UNA SECCION DERECHA SUPERIOR A LA DEL TUBO INTERIOR. LA EMBOCADURA (25) DEL TUBO INTERIOR (20) ESTA SITUADA EN LA CONTRACCION DE LA EMBOCADURA (5) DE LA TOBERA (1). LOS TUBOS INTERIOR Y EXTERIOR ESTAN DOTADOS DE VALVULAS DE REGULACION DE CAUDAL, Y UNIDAS A FUENTES DE GAS BAJO PRESION. SE PREVEEN MEDIOS PARA CAMBIAR LA SECCION DE LA EMBOCADURA (25) DEL TUBO INTERIOR (20) QUE PUEDEN ESTAR CONSTITUIDOS POR UNA PIEZA (23) SENSIBLEMENTE EN FORMA DE AGUJA, DESPLAZABLE A LO LARGO DEL EJE DEL TUBO INTERIOR (20), LA PARTE AGUDA DE LA AGUJA PUEDE TOMAR DIFERENTES POSICIONES EN EL INTERIOR DE LA PARTECONVERGENTE (21) DE TUBO INTERIOR.
