Abstract
A method of and apparatus for exchanging rollers in a continuous casting plant for strands, which plant has opposite roller paths for guiding the strand, involves moving the rollers to be exchanged into or out of their bearing places in the roller paths and transporting them away from or to the bearing place, respectively, in the region between the roller paths in the longitudinal direction thereof. Advantageously, a sled with recesses is provided for delivering and removing the rollers.

In a method of exchanging rollers in a plant for continuously casting strands, in which plant a plurality of rollers is arranged in bearing places and define opposite roller paths located at a distance from each other corresponding to the cross-section of the strand to be cast, the improvement comprising the steps of
- releasing a roller to be removed from its bearing place,
- moving said roller to be removed into the space between the opposite roller paths,
- transporting the roller to be removed longitudinally between the roller paths away from its bearing place,
- transporting a roller to be installed longitudinally between the opposite roller paths toward a free bearing place, and
- inserting the roller to be installed in the free bearing place.
An arrangement for exchanging rollers in a plant for continuously casting strands, in which plant a plurality of rollers is arranged in bearing places and define opposite roller paths located at a distance from each other corresponding to the cross-section of the strand to be cast, which comprises
- a sled movable between the roller paths and having recesses for accommodating rollers therein so as to transport the rollers from and to their respective bearing places in the roller paths, and
- displacement means for moving a roller to be removed from its bearing place into one of the recesses in the sled and moving a roller to be installed from one of the recesses in the sled into the respective bearing place.
