Abstract

EN UN APARATO DE FUNDICION CON UN HORNO (1) DE ARCO ELECTRICO Y UN PRECALENTADOR (2) DE CARGA EN FORMA DE CAMISA DISPUESTA LATERALMENTE CON RESPECTO AL HORNO DE ARCO ELECTRICO, LAS PAREDES EXTERIORES DE LOS PRECALENTADORES (2) DE CARGA Y LAS PAREDES SUPERIORES Y PAREDES INFERIORES DE LA PARED DE LA CUBETA (5) SE FORMAN CAMISAS FIJADAS (10) EN CONSTRUCCIONES (27) DE SUSTENTACION. A TRAVES DE UN MOVIMIENTO RELATIVO HORIZONTAL ENTRE LA CUBETA (3) DEL HORNO Y LA CONSTRUCCION (27) DE SUJECCION, JUNTAMENTE CON LA CUBIERTA (6) DE LA CUBETA, LA MATERIA DE CARGA PUEDE CARGARSE EN JAULA DE CHATARRA SIN NINGUN IMPEDIMENTO DESDE LA CAMISA HASTA LA CUBETA DEL HORNO O MEDIANTE LA CAMISA DEL HORNO ATRAVESANDO DIFERENTES ZONAS DE LA CUBETA (3) DEL HORNO. MEDIANTE UN BLOQUEADOR EN LA CAMISA SE RETIENE LA MATERIA DE CARGA GRUESO MIENTRAS TANTO SE CALIENTA LA FASE DE GRANO FINO.
