Abstract

The invention relates to a method of flying changing of working rolls in continuous casting and rolling installations and hot strip rolling mills, in particular in continuous hot strip rolling mills, wherein for exchange of working rolls by opening a rolling stand, those are disengaged from a to be rolled hot strip. According to the invention a regulated strip tension that can substitute the tension of the open rolling stand, is applied to the to-be-rolled hot strip with at least one hold-down roller that is introduced in a rolling line.
