A description is given of a method for braking moving rolled bars of differing lengths in the region of the approach roller table of cooling beds, in which method the braking force is provided by friction between the respective surface of the rolled bar and static and/or dynamic braking surfaces, e.g. those of braking slides and braking drivers, acting on it. Minimum length dimensions are achieved for a cooling-bed installation because the braking force on the rolled bars up to a predetermined limiting length is provided exclusively by static braking surfaces. Rolled bars with a length that exceeds this limiting length, on the other hand, are additionally subjected to the action of dynamic braking surfaces. The duration and/or intensity of action of the dynamic braking surfaces is/are determined by the difference between a likewise predetermined maximum length of rolled bar and the particular effective length of rolled bar. |
