Roller stand having elastically mounted supporting rollers

A roller stand for a billet strand casting system, comprising:

• a support frame for mounting at least one lower support roller;
• at least two lateral support rollers provided with respective position measuring devices;
• at least one upper support roller elastically mounted on the support frame and having an elasticity at least in a direction perpendicular to an axis of rotation of the at least one upper support roller;
• and
• a controller configured to:
• receive detected position changes of at least the lateral support rollers with respect to a reference during passage of a billet strand through a strand guide channel of the at least one roller stand, and
• determine, based on the detected changes, at least one of the position of the billet strand with respect to a center line of the strand guide channel and a form of the billet strand;
• wherein the at least two lateral support rollers are elastically mounted on the support frame by at least one passive elastic element having an elasticity at least in a direction perpendicular to axes of rotation of the at least two lateral support rollers;
• and
• wherein the at least one upper support roller is provided with a further position measuring device.
