A roller stand for a billet guide of a continuous billet casting machine, having a carrying frame for mounting at least one lower supporting roller, wherein the roller stand includes retaining devices for fastening intermediate-area spray bars. A billet guide and a continuous billet casting machine having such a roller stand.

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.

Apparatus to replace a guide unit in a continuous casting machine. A platform is positioned, during use, at the side of a casting line, and is provided with at least a first positioning zone of at least a first guide unit and at least a second positioning zone of at least a second guide unit. The platform is associated with a rotation device to take, on each occasion, the first positioning zone or the second positioning zone facing the side of the casting line. A movement device moves the second guide unit from a positioning zone outside the platform and, during use, in line with the casting line, to the second positioning zone of the platform and to move the first guide unit from the first positioning zone of the platform to the positioning zone outside the platform and, during use, in line with the casting line.
