Method for deploying set of working rolls from frame with locomotive arranged in roll changing hole under plant floor, involves coupling used set of working rolls on locomotive

摘要

The method involves coupling a used set of working rolls on a locomotive (1). The used set of working rolls are deployed in axial direction from the frame. The coupling of the used working rolls takes place at a high level tower (10) on the locomotive and the locomotives are decoupled from the used set of working rolls after the deployment. The tower of the locomotive is decoupled and the locomotive with the tower moves under the used set of working rolls in a roll changing hole (2) in the direction of the frame behind the used set of working rolls.
