Abstract

A continuously operating casting and rolling system with a strip tension control includes a casting unit having a melt-containing feed vessel with a horizontal casting channel and a discharge region in the form of a casting nozzle, and a primary cooling zone with two guide rolls and a circulating cooled casting strip and at least one downstream rolling unit having at least two drivable rollers. In order to minimize the tension on the cast strip, the casting unit and the subsequent rolling unit are mechanically decoupled, wherein for the decoupling at least one driver unit having at least two drivable rollers for driving the strip is arranged between the casting belt and the rolling unit.
