Abstract: A strand guide roller (100) of a strand guide device for guiding a cast strand (200) includes at least one first and one second sectional rollers arranged next to each other, includes a middle bearing (120-1, 120-2) located between both sectional rollers (110-1, 110-2) for receiving and supporting the roller journal (112-1) of the first sectional roller (110-1) formed on an end surface of the first sectional roller (110-1) adjacent to the second sectional roller (110-2), with the first and second sectional rollers being connected with each other outside of the middle bearing by a plug-in connection.

Abstract: The invention relates to a strand guide roller 100 of a strand guide device for guiding a cast strand 200. The stand guide roller includes at least one first and one second sectional roller arranged next to each other, wherein the first sectional roller 110-1 has a roller journal 112-1 at its end surface adjacent to the second sectional roller. In addition, the strand guide roller includes a middle bearing 120-1, 120-2 between both sectional rollers 110-1, 110-2 for receiving and supporting the roller journal 112-1 of the first sectional roller. In order to improve strand guidance by increasing the bearing surface for the strand 200, it is suggested, according to the invention, that the first and second sectional rollers be connected with each other outside of the middle bearing by a plug-in connection. Then, according to the invention, the middle bearing is formed simply as unsplit separate bearing with an essentially smaller window width in comparison with a split bearing.

Abstract: The invention relates to a mould for the continuous casting of molten metals, in particular steel, comprising cooling channels (1), such as cooling grooves, cooling slits or cooling drillings in the side of the mould (2) away from the melt contact surface. According to the invention, the heat transfer in the mould can be improved, whereby the geometric arrangement of the heat transfer planar surfaces of a cooling channel (1) or a group of cooling channels is adjusted in form, cross-sectional area, circumference, boundary surface qualities, orientation with respect to contact surfaces, arrangement and/or arrangement density with respect to the contact surfaces for the local formation of thermal flux density and/or temperature of the contact surfaces (18) during casting operation and in particular in the region of the meniscus (11).
