Abstract
EN UN PROCEDIMIENTO PARA LA FUNDICION EN CONTINUO DE CHATARRA E HIERRO EN BRUTO EN UN CONVERTIDOR U HORNO ALTO (1), SE CALIENTA EL CONVERTIDOR (1) PROXIMO AL FONDO (3) CON QUEMADORES (4) SUBESTEQUIOMETRICOS CUYAS LLAMAS SE ALINEAN RADIALMENTE EN EL INTERIOR DE LOS CONVERTIDORES (1), SE SUMINISTRA AIRE SECUNDARIO U O2 PARA LA COMBUSTION COMPLETA POR ENCIMA DEL PLANO DEL QUEMADOR, SE HACE SALIR LA FUNDICION POR UN MECANISMO (6) SANGRADOR ACOPLADO LATERALMENTE A UN CONVERTIDOR (1) Y EN ALGUNOS CAOS CON ESCORIA EN UNA CHATARRA (8) MOVIBLE Y SE CIERRA EL MECANISMO SANGRADOR PARA EL CAMBIO DE LA CUCHARA. EN EL MECANISMO SANGRADOR (6) SE ACOPLA UN MECANISMO DE CIERRE (11) QUE SE SITUA EN UNA APERTURA (7) DE SANGRADO RADIAL DE LOS CONVERTIDORES U HORNO ALTO Y/O EN EL MECANISMO SANGRADOR (6) SITUADO EN UNA APERTURA (7) DE SANGRADO RADIAL DE LOS CONVERTIDORES U HORNO ALTO SE ACOPLA UN ORIFICIO (9) DE SANGRADO PARALELO AL EJE (10) DEL CONVERTIDOR (1) U HORNO ALTO (1).
