Embodiment Construction

[0015] 1 and 2 show an electromagnetic braking device according to the present invention, which includes a yoke 7, a current-carrying coil 3 and a ferromagnetic core 5. The electromagnetic braking device is fixed on the rail beam 11 by means of two differently long and non-parallel levers 9, 10 and is centered and hinged by an adjustment mechanism 6 such as a hydraulic cylinder. On the one hand, the resulting curved movement of the electromagnetic brake enables the electromagnetic brake to be moved almost horizontally out of the water tank 2 and the frame 1 of the mold. On the other hand, the space-saving resting position between the rail 11 and the mold ensures a smooth exchange of the mold and the strand guide segments. Furthermore, this arrangement not only allows a shorter stroke than a linear infeed, but also a lower adjustment force than a linear infeed, since the system is close to its top dead center. The continuous casting mold and the electromagnetic braking device ...

Abstract

The invention relates to an electromagnetic braking device for the steel melt running within the continuous casting ingot in a continuous casting unit. The electromagnetic brake device comprises at least one coil ( 3 ) with a ferromagnetic core ( 5 ), arranged on the broad side of the ingot and at least one yoke ( 7 ) provided on the above. In order to reduce the oscillating masses on the ingot components and to permit the retro-fitting of electromagnetic brakes to conventional continuous casting machines, the electromagnetic brake, comprising yoke ( 7 ), coil ( 3 ) and ferromagnetic core ( 5 ), is embodied such as to pivot inwards or outwards, preferably by means of two unequal length, non-parallel levers in or on the continuous casting ingot, using an actuator ( 6 ).

Description

technical field [0001] The invention relates to an electromagnetic braking device for molten steel flowing into a continuous casting mold of a continuous casting plant, comprising at least one coil associated with the wide side walls of the mold and having a ferromagnetic core, and at least one coil associated with the coil yoke. Background technique [0002] Continuous casting plants of the type described above are already known. The molten steel flowing into the mold is braked and oriented in order to reduce eddy currents by a magnetic field acting between the wide side walls of the continuous casting mold. In order to generate this magnetic field, a ferromagnetic core is fastened to the copper plate on the wide side wall of the continuous casting mold, said ferromagnetic core being excited by a coil surrounding the ferromagnetic core. The braking and directional alignment of the casting molten steel caused by the magnetic field results in a smooth steel pool and a reduc...
