Abstract
A device, for continuously or semicontinuously casting of metal in a casting mould, for braking and splitting up a primary flow of hot melt supplied to a casting mould, and controlling the flow of melt in the non-solidified portions of a cast strand which is formed in the casting mould. The device comprises a plurality of water box beams which support and cool the casting mould and supply a coolant to the casting mould, and a magnetic brake. The magnetic brake is adapted to generate at least one static or periodic low-frequency magnetic field to act in the path of the inflowing melt and comprises at least one magnet to generate the magnetic field, at least one core to transmit the magnetic field to the casting mould and a cast strand, and at least one magnetic return path to close the magnetic circuit. The water box beam is completely or partially arranged in a magnetically conducting material. A magnetic brake comprises at least one magnetic circuit which comprises the casting mould and the cast strand into a magnetic circuit. The magnet is arranged in a recess in a water box beam. The magnet and the magnetic return path are integrated so that the magnet and the magnetic return path are arranged inside the rear wall of the water box beam.
