The invention relates to a method for extending the casting cycle for the two-roll strip casting of a steel strip, with in-line rolling thereof, said steel strip being rolled in at least two successive rolling units ( 1, 2 ) of a rolling mill comprising replaceable working rolls ( 5 a , 5 b , 6 a, 6 b). The aim of the invention is to be able to carry out the casting process independently from the roll replacement. To this end, the working rolls ( 6 a , 6 b) of one rolling unit ( 2 ) are replaced during the casting, below or above the steel strip ( 23 ). The invention also relates to an installation for carrying out the method, by which means the working rolls ( 6 a , 6 b) can be lifted off the steel strip ( 23 ) by means of lifting devices ( 17 ) so as not to damage the strip during the replacement of the rolls.
