A method and roll segment ( 1 ) for determining core solidification and/or the liquid crater tip in the continuous casting of metals, particularly steel materials, inside a roll segment ( 1 ) of a support roller gantry ( 2 ), wherein the upper frame ( 3 ) thereof supporting the upper rollers ( 4 ) can be drivingly adjusted via hydraulic piston-cylinder units ( 6 ), which are arranged in the corners ( 5 a- 5 d) of a polygon, counter to the lower rollers ( 8 ) of a lower frame ( 7 ), according to the thickness of the billet, working in a more accurate manner, using an independent pair ( 14 ) of piston-cylinder units ( 6 ) with an external or internal measuring device ( 13 a, 13 ) in order to adjust a rotationally driven, individual upper roller ( 4 ), taking into account the measuring values for positional adjustment or force adjustment in order to determine the position of core solidification and/or the liquid crater tip in the cast billet. |
