Abstract (en)
[origin: WO2011124585A1] The invention relates to a method for the flying changing of working rolls in continuous casting and rolling installations and hot strip rolling mills, in particular continuous hot strip rolling mills, wherein, to exchange the working rolls by opening the roll stand (2), they can be disengaged from the hot strip to be rolled. According to the invention, a strip tension that can be regulated and substitutes the strip tension of the opened roll stand (2) can be applied to the hot strip (6) to be rolled, before and/or after it enters the opened roll stand (2), by means of at least one hold-down roller (5) that can be introduced into the rolling line.
