Method for extending the casting cycle for two-roll strip casting, and installation for carrying out said method

摘要

A method for extending the casting cycle for the two-roll strip casting of a steel strip, with inline rolling thereof, the steel strip being rolled in at least two successive rolling units of a rolling mill having replaceable working rolls. The casting process is carried out independently from the roll replacement by replacing the working rolls of one rolling unit during the casting, below or above the steel strip. An installation for carrying out the method includes a lifting devices for lifting the working rolls off the steel strip so as not to damage the strip during the replacement of the rolls.
