The invention relates to 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, b) the amplitude (A) of the gap oscillation is set to a value which does not induce any plastic deformation of the strand shell, c) the current gap (s) is recorded, d) at the same time, the actuating force (F) of the adjusting elements and the amplitude (A) of the actuating force are determined and e) with increasing amplitude (A) of the actuating force (F), the gap (s) is set to a predeterminable value and/or is pressure-controlled by means of at least one adjusting element.
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:
Stand of a strand guiding assembly which is arranged downstream of a permanent mold in a continuous casting installation for producing slabs from steel, which stand has lower and upper frames provided with guide rollers which can be set in their distance with respect to each other by pressure- and/or distance-controlled adjusting elements to a gap through which a cold strand can also be transported, characterized in that one of the outer guide rollers (24) of the upper frame (22) can be driven, in that the adjusting elements (31) assigned to the drivable guide roller (25) can be brought into connection with the computer (45) in terms of control technology via pressure-control devices (43, 44) and the other adjusting elements (31) can be brought into connection with said computer (45) in terms of control technology via position-control devices (41, 42).
