Electromagnetic braking device for molten steel that flows into a continuous casting mold

摘要

The invention relates to an electromagnetic braking device for molten steel that flows into a continuous casting mould (1). Said device comprises at least one solenoid (2) with a ferromagnetic core (5) that is allocated to the broad sides (3, 4) of the mould. To reduce the oscillating mass and at the same time increase the strength of the magnetic field, the core (5) consists of a primary part (6) that houses the solenoid (2) and can be displaced at a distance from the broad side walls (3, 4) and attachments (8, 8′) that are fixed in water tanks (7, 7′) of the mould (1). When combined in their operating position, the core parts (6, 8) produce U-shaped yokes (9, 9′) for generating a closed magnetic flux (10) and when moved apart, cause the magnetic flux (10) to be interrupted.
