Abstract
LA INVENCION SE REFIERE A UN DISPOSITIVO DE INCLINACION PARA UN HORNO DE ARCO DE CORRIENTE DIRECTA Y UN PROCEDIMIENTO PARA EL VACIADO COMPLETO DEL HORNO MIENTRAS EL HORNO SE ENCUENTRA EN OPERACION CON UN SUMINISTRO CONTINUO DE CHATARRA A TRAVES DE UNA ABERTURA (15) LATERAL EN EL RECIPIENTE (1) DEL HORNO Y RETIRADA DEL FONDO. LA RAMPA (14) DE CHATARRA DEBE PERMANECER EN LA ABERTURA (15) DEL HORNO DURANTE LA CARGA COMPLETA TOTAL, FUSION, DESESCORIADO Y OPERACIONES DE COLADA DE METAL FUNDIDO; DEBE SER BASCULADA HACIA AFUERA SOLAMENTE DURANTE EL VACIADO COMPLETO DEL HORNO. EL DISPOSITIVO DE INCLINACION DESCRITO DISPONE DE UNA LEVA (10) SOBRE UN BASTIDOR (4) DE LAMINACION, DE FORMA QUE EL PUNTO (5A) MEDIO DEL RODILLO DE LAMINACION PERMANECE EN LA POSICION CERO EN UN CAMPO DE INCLINACION DE + 15 , Y SOLAMENTE CUANDO EL HORNO ESTA COMPLETAMENTE VACIO SE MUEVE A OTRA POSICION (5B) EN UNA DIRECCION PARALELA CON RESPECTO A LA ABERTURA (2A) DE GOLPE DEL FONDO. LA POSICION DE LA ABERTURA (2B, 2C) DE GOLPE DEL FONDO DEBE CAMBIAR SOLAMENTE EN UNA EXTENSION INSIGNIFICANTE EN EL CAMPO DE INCLINACION DE POR EJEMPLO MAS 10 HASTA MAS 25 ELECTRODO (13) DEL FONDO LOCALIZADO FUERA DEL RECIPIENTE (1) DEL HORNO A PARTIR DEL CALOR RADIADO POR EL ACERO EN EL RECIPIENTE (11) DEL HORNO DE FUNDICION.
