Abstract
PROCEDIMIENTO Y APARATO PARA EL PRECALENTAMIENTO CONTINUO DE MATERIALES DE CARGA PARA UN HORNO DE FABRICACION DE ACERO, QUE INCLUYE MEDIOS PARA PRECALENTAR CON LOS GASES DE EMISION, DEL HORNO Y QUEMADORES EN LA CAMARA DE PRECALENTAMIENTO. SE FORMAN JUNTAS PARA EVITAR EL ESCAPE CONTROLADO DE GASES DE LA CAMARA Y EL AIRE DE ENFRIAMIENTO SE CALIENTA TAMBIEN PARA SER UTILIZADOS EN OTROS MEDIOS. LA INVENCION CONTRIBUYE AL PROCESO DE LA FABRICACION CONTINUA DE ACERO, INCLUYENDO LA CARGA Y LA COLADA, MIENTRAS SE MANTIENE UNA PLENA POTENCIA ELECTRICA, Y EJERCIENDO UN BUEN CONTROL EN LA CALIDAD Y EN LA QUIMICA DEL PRODUCTO.
