Abstract

A LAS TUBERIAS DE INYECCION (14) DE LOS HORNOS DE INYECCION SE LES SUMINISTRA CARBON EN POLVO Y OXIGENO, A TRAVES DE LANZAS (22, 23), QUE COMPRENDEN DOS TUBOS CONCENTRICOS (25, 26) QUE ACABAN ADYACENTES A LAS TOBERAS (13) O EN ELLAS. LA PUNTA TERMORRESISTENTE DE CADA LANZA, FORMA UNA PROLONGACION DE LA ENTRADA DEL TUBO DE SUMINISTRO DE CARBON EN POLVO, Y TAMBIEN FORMA UNA PROLONGACION EN EL ESPACIO ANULAR ENTRE LOS TUBOS (25, 26), GENERANDO UN NUMERO DE CANALES HELICOIDALES (42) A TRAVES DE LOS QUE PASA EL OXIGENO. ES VENTAJOSO TENER MAS DE UNA LANZA EN CADA TUBERIA DE INYECCION, Y DISPONER LANZAS OBLICUAMENTE DENTRO DEL CANAL DE INYECCION DE CALOR (24), FORMADO POR LA TUBERIA DE INYECCION (14) Y LA TOBERA (13).
