Abstract

Procedimiento de tratamiento termoquímico en continuo de cintas metálicas, particularmente de acero, del tipo oxido-reducción, según el cual la cinta se desplaza a través de un horno en una atmósfera protectora, caracterizado porque la indicada cinta pasa a través de al menos un dispositivo de aislamiento parcial o total, situado en el seno de al menos una sección del horno, o entre dos secciones, calentándose la cinta, en este dispositivo de aislamiento, en atmósferas con punto de condensación adaptado a cada cinta en función de la composición específica del acero, de forma que la atmósfera sea oxidante para algunos elementos de adición, pero permanezca reductora para el hierro.
