  • a metallic melt is fed to a cooled mold, solidified in it at least in the edge zone and usually continuously - already in the form of a strand - fed from the mold of the mold downstream strand guide of the continuous casting machine and conveyed through the strand guide.
  • the strand guide Through the strand guide the strand is guided, supported and further cooled.
  • the strand guide usually has a plurality of strand guide segments with strand guide rollers. At least some of these strand guide rollers are usually to several or individually by means of an adjustment against the strand anstell- or pressed.
  • Each strand guide roller unit has an individually engageable strand guide roller, a crosshead, a roller carrier and an adjusting device, wherein the adjusting device is connected in each case by means of rotary joints rotatably movable with the crosshead and with the roller carrier.
  • a strand guide roller unit of the type mentioned in which the adjusting device according to the invention by means of at least one storage translationally and rotationally movably connected to the crosshead or with the roller carrier.
  • the invention is based on the consideration that a sufficiently movable mounting of the adjusting device on the crosshead and / or on the roller carrier, in particular for avoiding an undesirable transverse force and / or a moment effect on the adjusting device, is necessary.
  • the invention proceeds from the recognition that the usual rotationally movable connection of the adjusting device to the crosshead and to the roller carrier, in particular by means of rotary joints arranged on both sides of the adjusting device, can be disadvantageous.
  • this connection which is pivotal on both sides, or mounting can be associated with increased design complexity.
  • the equipment of the crosshead and the roller carrier each with at least one required for the pivotal connection bearing element - for example, a transverse bore for receiving a bolt, a bearing seat or the like - may affect the mechanical properties of the strand guide roller unit.
  • connection which is pivotal on both sides, can require a flexible tubing for supplying an active medium, for example a hydraulic fluid or the like, to the adjustment device in order to compensate for the rotational movement.
  • an active medium for example a hydraulic fluid or the like
  • Such flexible, flexible hoses can, in particular under the ambient conditions prevailing in continuous casting, they are easily damaged. As a result, leakage of the active medium from the hose may occur, resulting in undesirable contact of the strand with the active medium and ultimately a fire hazard.
  • the invention enables a sufficiently movable mounting of the adjusting device. An undesirable transverse force and / or a moment effect on the adjusting device is thereby avoided. It is sufficient if the adjusting device is connected to either the crosshead or the roller carrier so mounted. On a both sides rotatory movable connection of the adjusting means of hinges can therefore - overcoming the aforementioned disadvantages - be dispensed with.
  • the "Anstatt the strand" in the sense of the present invention may mean that the strand guide roller for impressing a force on the strand in the direction of the strand is moved, adjustable or deliverable.
  • the adjusting device can impose a force and / or a displacement on the roller carrier or indirectly on the strand guiding roller.
  • the force and / or the displacement can be effected along an adjustment direction.
  • the adjustment direction may be a direction along a direction of action of the adjusting device, in particular a direction along a stroke direction of a hydraulic cylinder or the like.
  • the adjustment direction may be a direction transverse to a casting or a conveying direction of the strand through a strand guide segment.
  • the adjusting device can then be connected in a translationally movable manner by means of the mounting, if the adjusting device is opposite to the one with it by means of
  • the storage connected component can perform a defined by a structural element direction and magnitude translational relative movement.
  • the adjusting device can then be rotationally movably connected by means of the mounting, when the adjusting device can execute a rotary relative movement defined by direction and magnitude relative to the component connected to it by means of the bearing.
  • the adjustment is translatorily and rotationally fixed connected to the not connected by the storage crosshead or with the not connected by the storage roller carrier.
  • the adjustment is advantageously at its end opposite the storage end - ie either on the crosshead or on the roller carrier - translationally and rotationally fixed, for example by means of a screw and / or a welded joint. That is, the adjustment can be connected at one end by means of storage with the roller carrier translationally and rotatably movable and the other end, the adjustment can be translationally and rotationally fixed connected to the crosshead. Alternatively, the adjustment can at one end by means of storage with the crosshead translationally and rotationally movably connected and the other end, the adjustment can be translationally and rotationally fixed connected to the roller carrier.

  • an advantageously constructed strand guide roller unit is achieved.
  • such a strand guide roller unit can be achieved with a comparatively reduced height and reduced mass.
  • the adjusting device can then be connected in a translationally fixed manner to a component if a translatory relative movement of the adjusting device and of the component relative to one another - as would be made possible, for example, by a guide, a slide rail or the like - is prevented by a constructive element.
  • a translational relative movement due to an elastic deformation must or can not be prevented of course.
  • the adjusting device can then be rotationally fixedly connected to a component, if a rotational relative movement of the adjusting device and the component against each other - as would be possible, for example, by a hinge, a linkage or the like - is prevented by a constructive element.
  • a rotational relative movement due to an elastic deflection, an elastic shear deformation or the like must of course not be prevented.
  • the bearing has a translational degree of freedom in the axial direction of the individually engageable strand guide roller.
  • a translational degree of freedom can be understood to mean a kinematic possibility of movement along a direction predetermined by a constructive element. Due to the translatory degree of freedom of storage, a relative mobility of the adjusting device to the crosshead or the roller carrier - depending on whether the adjustment by means of storage with the Crosshead or connected to the roller carrier - can be achieved. In this way, a transmission of undesired transverse forces-which can lead to tilting of the roller carrier as part of a strand guide segment and / or to an impairment of the adjusting device-can be minimized on the adjusting device.
  • the bearing has a translationally movable sliding guide.
  • the sliding guide is a linear sliding guide for guiding a translational relative movement between the adjusting device and the roller carrier or between the adjusting device and the crosshead.

Due to the rotational degree of freedom of storage, a relative rotational mobility of the adjusting device to the crosshead or the roller carrier - depending on whether the adjustment by means of the storage with the crosshead or with the Roller carrier is connected - can be achieved. In this way, a transmission of an undesired torque - which can lead to a jamming of the roller carrier in the frame and / or to an impairment of the adjusting device - can be avoided on the adjusting device.

  • the adjusting device is connected by means of the bearing with the roller carrier.
  • the adjusting device is connected in a translatory and rotationally fixed manner to the crosshead. Due to the thus fixed connection between the crosshead and the adjusting device, a leakage-prone flexible tubing between the crosshead and the adjusting device, for example to an agent supply, can be avoided. In addition, structurally complex, space-consuming and the mechanical properties of the crosshead impairing bearing elements can be avoided. In this way, the crosshead can be achieved with comparatively low height and comparatively low mass with comparable or improved strength properties.
