A device for continuously manufacturing a cast strand by continuous casting of liqui metal, melt, wherein the flow of the liquid metal in the non-solidified portions of the strand is controlled by means of a static or periodic low-frequency magnetic field. A mould is adapted to be supplied with the melt. The mould comprises copper plates (2a, 2b) which form a casting mould with a rectangular cross section, water box beams (3) which are arranged outside the copper plates to support and cool them, and a member (4) holding the mould together. Magnetic field-generating devices, magnets, are provided close to the mould to generate a static or periodic low-frequency magnetic field which acts in the path of the inflowing melt and divides the primary flow as well as checks any secondary flows arising. Each magnet comprises a front core (5), a rear and a coil (7). The front core is a fully integral part of the water box beam and the rear core comprises a rear movable part (6b) which is movable in a direction which substantially coincides with the direction of the field.
