Abstract

A a process for producing slabs from steel, in which the strand leaves a permanent mold with liquid melt enclosed by the strand shell and, in a downstream strand guiding assembly, the gap between guide rollers mounted in stands is set infinitely variably by adjusting elements connecting lower and upper frames, characterized by the following steps: a) the gap(s) is changed by an oscillation about a predeteminable center line (c) of the gap in such a way that the dynamic influences on the guide rollers are negligible, and no plastic deformation of the strand shell occurs; b) the current gap (s) is recorded, c) at the same time, the actuating force (F) of the adjusting elements and the amplitude (A) of the actuating force are determined, and d) with increasing amplitude (A) of the actuating force (F), the gap (s) is set to a predeterminable value and/or is pressure-controlled by at least one adjusting element.
