Claim:
Continuous casting plant having a mould from which a cast strand is continuously cast, and at least one module in which the cast strand is guided along a curved guideway formed by guide rollers arranged one after the other and in a cooling chamber the improvement comprising: said guide rollers including at least a first fixedly mounted guide roller arranged on a radially outermost side of the curved guideway and adapted to be situated on a first side of the cast strand, and at least second, third and fourth guide rollers each adapted to be situated on a respective side of the cast strand other than the first side of the cast strand; respective actuating members that adjust said second, third and fourth guide rollers in an approximately perpendicular direction to the respective side of the cast strand such that said second, third and fourth guide rollers are adjustable to be continuously in contact with the cast strand, said actuating members enabling a contact force of the respective one of said second, third and fourth guide rollers against the respective side of the cast strand to be adjustable, said actuating members of said third and fourth guide rollers each including a sleeve-shaped part that carries the respective one of said third and fourth guide rollers, each of said sleeve-shaped parts being pivotable about a respective axle fixed to said frame, said sleeve-shaped parts being rotationally connected to one another via interengaging toothed segments, a frame, said respective actuating member for said second guide roller including a U-shaped holder that carries said second guide roller, said U-shaped holder being pivotally mounted to said frame, a first hydraulic cylinder or actuator for pivoting said U-shaped holder or for pressing said second guide roller against the cast strand, and a second hydraulic cylinder or actuator for actuating one of said sleeve-shaped parts to enable symmetrical pivoting of said sleeve-shaped parts or for concentrically pressing said third and fourth guide rollers against the cast strand running in a desired position, the contact force of said second, third and fourth guide rollers against the respective side of the cast strand being measured.
