A roller stand for a continuous billet casting machine, having a carrying frame for mounting at least one lower supporting roller and at least two lateral supporting rollers. The lateral supporting rollers are mounted elastically on the carrying frame by means of at least one passive elastic element, and have an amount of elasticity at least in a direction perpendicular to the axes of rotation of the lateral supporting rollers. A method for determining the position and/or the shape of a billet is provided. During passage through at least one roller stand, alterations in the position at least of the lateral supporting rollers relative to a reference are detected and, on the basis of this information, the shape of the billet and/or the position of the billet in relation to the center line of the billet-guide channel are/is determined.

A coolant nozzle () for cooling a metal strand in a continuous casting installation has a mouthpiece (), which is arranged at a nozzle outlet end () and through which liquid coolant () can emerge from the coolant nozzle (). To allow a rapid buildup of pressure at the coolant nozzle (), it provides a feed (), which is formed as a tube-in-tube system () arranged upstream of the mouthpiece () in the direction of through-flow () and has a feed outlet end (), through the first tube () in which control air () can be brought up to the feed outlet end () and through the second tube () of which the liquid coolant () can be fed to the mouthpiece () by way of the feed outlet end (), and also provides a control valve (), which is integrated in the feed (), is arranged at the feed outlet end (), can be actuated pneumatically by using the control air () and is intended for controlling the feed of the liquid coolant () into the mouthpiece ().
