Abstract

PARA REDUCIR EN LO POSIBLE UNA CANTIDAD DE ESCAPE DE UN GAS DE HORNO DE ENTRE UNA ALMOHADILLA DE SELLAJE FLEXIBLE (5) Y UN RODILLO ROTATORIO FLEXIBLE (6) DE UN APARATO DE SELLAJE (2) EN UNA ZONA DE SALIDA/ENTRADA DE UN HORNO DE TRATAMIENTO DE CALOR, UTILIZANDO UNA ATMOSFERA REDUCTORA DE GAS DE HIDROGENO PARA LLEVAR A CABO TRATAMIENTO AL CALOR TAL COMO RECOCIDO, RECOCIDO DE LIBERACION DE MANCHAS, ETC., BAJO EL ESTADO EN EL QUE UNA PELICULA DE OXIDO NO SE FORMA SOBRE LA SUPERFICIE DE UNA TIRA DE METAL, Y PARA ASEGURAR ESTABLEMENTE UNA EXCELENTE SELLABILIDAD POR UN TIEMPO EXTENDIDO; LA PRESENTE INVENCION DISPONE UNA PLURALIDAD DE CONJUNTOS DE MECANISMOS DE PRENSA (7) OPERADO DESDE FUERA DE UNA PLANCHA LATERAL (3A) DE UNA PARED DEL HORNO (3) EN UNA DIRECCION AXIAL DEL RODILLO FLEXIBLE ROTATORIO (6), Y PRENSA SOLAMENTE LA PARTE NECESARIA DE LA ALMOHADILLA DE SELLO FLEXIBLE (5) EN LA DIRECCION DEL RODILLO ROTATORIO FLEXIBLE DESDE EL LADO INTERNO DEL HORNO MEDIANTE EL ELEMENTO DE PRENSA (7B) DE SUMECANISMO (7) A TRAVES DE UNA PLACA DE SELLAJE (4), PARA CERRAR POSITIVAMENTE SOLO LA PARTE, POR LA QUE SE ESCAPA EL GAS, ENTRE LA ALMOHADILLA DE SELLO FLEXIBLE Y EL RODILLO ROTATORIO FLEXIBLE. LA PRESENTE INVENCION CONSTITUYE LA SECCION DE LA CAPA DEL HORNO DE LA ALMOHADILLA DE SELLO FLEXIBLE MEDIANTE UN MATERIAL QUE SATISFACE UN INDICE DE OXIGENO LIMITADOR DE VALOR LOI DE AL MENOS 26, Y UNA SUPERFICIE EXTERNA DEL HORNO DEL RODILLO ROTATORIO FLEXIBLE PREFERIBLEMENTE MEDIANTE UN ELEMENTO FLEXIBLE ESPECIFICO CON UNA RESISTENCIA AL CALOR PARA EVITAR LA CAIDA DE LA SELLABILIDAD INCLUSO CUANDO SE PRODUZCA UN INCENDIO EN LA PROXIMIDAD DEL APARATO DE SELLAJE (2) DURANTE UN PERIODO CORTO.
