Abstract
A method and a device for adjusting one or more roll segments ( ) in a continuous casting installation for metals, especially for steel materials, the rolls ( ) of which adjusted in the segment upper frame ( ) and the segment lower frame ( ) on frame cross members ( ) by pairs ( ) of hydraulic piston-cylinder units in a position-and/or pressure-controlled manner, wherein an operation for guiding and/or pressing the casting strands ( ) is switched from a position-controlled to a pressure-controlled operation when pressure within the respective pair ( ) of piston-cylinder units reaches a predetermined maximum value, whereby an improved reaction is effected by operating the piston-cylinder unit of every roll segment ( ) in the case of overload, in subsequent steps at a reduced pressure or in a pressureless switching mode until the switching mode is reached in which the segment upper frame ( ) can be opened to some extent.
