Abstract

A disadvantage of continuously casting thin metal strips in a continuous casting plant (1) wherein the casting strand (7) exits the mould (2) in a downward direction and is guided in a vertical strand guide (3) with the help of pairs of driver rolls (4, 5) for supporting and conveying the strand (7), is that the force with which the driver rolls (4, 5) are pressed against the strand (7) results in the unchecked rolling of the strand while it is still soft. The aim of the invention is to solve this problem. To that end, the driver rolls (4, 5) are pressed against the strand (7) with a variable pressure (P1, P2) which is regulated “on-line” in accordance with the thickness (d3, d4) of the strand (7), in such a way as to obtain and maintain a constant strand thickness.
