A device for the hydraulic positioning of structural component parts, in particular rollers of strand guide segments of a continuous casting installation, with hydraulic cylinders, each of which is divided into a cylinder space and an annular cylinder space by a piston having a piston rod. The cylinder spaces can be connected to a pressure source by of control members. Hydraulic connection lines are reduced or components used are reduced. Either the annular cylinder space is acted upon by a pressure which is adjustable but which then remains constant, while the pressure applied to the piston in the cylinder space is position-controlled or pressure-controlled, or the cylinder space is acted upon by a pressure which is adjustable but which then remains constant, while the pressure applied to the piston in the annular cylinder space is position-controlled or pressure-controlled.

Position-controlled or pressure-controlled device for the hydraulic positioning of components

The invention relates to a method for the continuous casting of a metal strand (), in which the cast strand () leaves a die () vertically or arcuately downwards and is subsequently guided in a strand guide (), wherein the strand guide () has a number of pairs of rollers (), which define between them an adjustable roller nip (), and wherein, at the start of casting, to close the die () in the downward direction, a piece of strand () is introduced into the die () and is followed by the cast strand (). In order to improve the adjustment of the roller nip, the invention provides that the piece of strand (), which is produced with a defined or calibrated thickness (d), is inserted between the respective pairs of rollers to calibrate and/or measure the roller nip ().
