Abstract
EL HORNO COMPRENDE UN ESPACIO EN LA VERTICAL DE UNA CARGA EN EL QUE DESEMBOCA AL MENOS UN INYECTOR DE GAS OXIGENADO QUE ATRAVIESA EL RECINTO DEL HORNO PARA SUMINISTRAR EN ESTE ESPACIO UN CHORRO DE GAS NO RADIAL RESPECTO DE UN EJE VERTICAL DEL ESPACIO. CADA INYECTOR COMPRENDE A) UNA CABEZA (14) DISPUESTA EN EL ESPESOR DE LA PARED (1) DE DICHO RECINTO Y QUE PRESENTA UN PASO DE GAS DE EJE (11) INCLINADO CON UN ANGULO (ALFA) PREDETERMINADO SOBRE UN EJE (15) SENSIBLEMENTE EN LA VERTICAL DE LA CARGA Y B) UN CUERPO (16) SENSIBLEMENTE CILINDRICO QUE PROLONGA LA CABEZA Y EL PASO DE GAS AL EXTERIOR DEL HORNO SIGUIENDO ESTE EJE (15) SENSIBLEMENTE RADIAL, EL MISMO SENSIBLEMENTE PERPENDICULAR A LA PARED (1) ATRAVESADA. APLICACION EN UN HORNO ELECTRICO DE FUSION DE CHATARRA PARA LA PRODUCCION DE ACERO.
