Device for casting in a mould

A device, for continuous or semicontinuous casting of metal in a casting mould, of braking and splitting up a primary flow of hot melt supplied to the casting mould, and controlling the flow of melt in non-solidified portions of a cast strand, wherein the cast strand is formed during the passage through the casting mould which is cooled and open In both ends of the casting direction, the device comprises:

• a plurality of water box beams arranged around the casting mould to support and cool the casting mould and to supply a coolant to the casting mould and a magnetic brake,
• said 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,
• said magnetic brake comprises
• at least one magnet for generating the magnetic field,
• at least one core for transmitting the magnetic field generated by the magnet to the casting mould and the cast strand, and
• at least one magnetic return path,
• the magnetic circuit comprises the casting mould and the cast strand, wherein the water box beams, at least in part, comprise a magnetically conducting material,
• the magnet is arranged in a recess in a water box beam,
• the magnetically conducting material is adapted to be part of the magnetic return path, and
• the magnet and the magnetic return path are Integrally arranged into the water box beam such that the magnet and the magnetic return path, in their entirety, are inside the rear wall of the water box beam.
