Abstract (en)
The invention relates to a casting roll (12), for the casting of metal strip (21) by continuous casting in a twin roll caster,- having a casting surface (12A) formed by a substantially cylindrical tube (120),- having at least one substantially axially symmetric expansion element, e.g. an expansion ring (101-103), arranged within the cylindrical tube (120), and the expansion element adapted to increase in radial dimension causing the cylindrical tube to expand changing roll crown of the casting surfaces (12A) of the casting rolls and thickness profile of the cast strip during casting,whereas at least one expansion element is movable in axial direction of the casting roll (12). The method of continuously casting thin strip by controlling roll crown is characterized in that at least one expansion element is moved in axial direction of the casting roll (12) to an axial position where the strip thickness of the cast metal strip (21) shall be reduced.
