Abstract

LAS CARGAS DE PIEZAS DE TRABAJO SON TRANSPORTADAS POR CICLOS SOBRE ELEMENTOS DE FONDO (12) A LO LARGO DEL HORNO CONTINUO, Y SERAN SEPARADAS APROXIMADAMENTE EN CADA CICLO, EMPEZANDO POR EL EXTREMO DE LA PARTE DE ESCAPE (9) DEL HORNO CONTINUO, SIENDO LUEGO ELEVADAS DESDE ABAJO Y TRASLADADAS ALREDEDOR DE UN PASO. DE ESTA FORMA, INCLUSO LAS CARGAS DE PIEZAS EXTREMADAMENTE PESADAS, COMO CHAPAS EN ROLLO, PUEDEN SER TRATADAS CON CALOR EN EL HORNO CONTINUO. UN TRANSCONECTADOR (13) ES EL QUE SE OCUPA DEL TRANSPORTE; ESTE ES CONDUCIBLE POR DEBAJO DEL FONDO DEL HORNO (14) A UN HORNO INFERIOR (15) EN DIRECCION LONGITUDINAL AL HORNO Y PUEDE PASAR GRACIAS A UN DISPOSITIVO ELEVADOR (18) A TRAVES DEL SUELO DEL HORNO (14). PARA ELLO, EL HORNO MUESTRA DOS ESCOTADURAS (20, 21) QUE TRANSCURREN EN DIRECCION LONGITUDINAL AL HORNO. LOS ELEMENTOS MOVILES DEL FONDO (12) FORMAN UN FONDO SUPERIOR CERRADO, QUE CUBRE LAS ESCOTADURAS (20, 21) DEL FONDO DEL HORNO. EL HORNO INFERIOR (15) ESTA TAMBIEN AISLADO TERMICAMENTE.
