Abstract

Método para tratar tiras de acero aleado, que comprende el peso de un segmento de dicha tira, de un tipo determinado, continuamente a través de una línea de tratamiento térmico, luego a través de un baño de sal fundida contenido en un tanque provisto de un rodillo de inmersión accionado, por debajo del cual pasa la tira en contacto con él, luego a través de un tanque de enjuagado, luego a través de un baño desoxidante, la sujeción del extremo posterior de un segmento de tira de acero de aleación al extremo anterior de otro segmento de tira de acero aleado, la continuación de las anteriores operaciones hasta que ha de tratarse una tira de acero aleado de un tipo que no ha de someterse al baño de sal, la ulterior sujeción del extremo anterior de un segmento posterior del último segmento del primer tipo de tira citado, la elevación del mencionado rodillo de inmersión y de sus medios accionadotes por encima del baño de sal fundida, de manera que el segundo tipo de tira eluda dicho baño, y la continuación de esta operación, con el rodillo de inmersión elevado o descendido, según el tipo de acero de aleación objeto de tratamiento.
