Abstract

A method for continuous casting of thin slabs may involve feeding a molten metal into a mold, molding a partially solidified thin-slab strand from the molten metal in the mold, reducing a flow rate of the molten metal in the partially solidified thin-slab strand by way of an electromagnetic brake positioned in a region of the mold, and removing the partially solidified thin-slab strand from the mold by way of a strand guiding system. Unsolidified parts of the partially solidified thin-slab strand may be stirred by an electromagnetic stirrer arranged underneath the mold downstream along a strand takeoff direction of the thin-slab strand. Further, a traveling electromagnetic field may be produced by the electromagnetic stirrer in a region of the thin-slab strand that is at a distance from the mold of between 20 and 7000 millimeters along the strand takeoff direction.
