Definitions
- the invention relates to an electromagnetic brake device for in the Continuous casting mold of a continuous casting machine inflowing molten steel, the at least one coil associated with the Kokillenbreitrise with a ferromagnetic Core and at least one associated with this yoke consists.
- Continuous casting of the aforementioned type are known.
- the in the Mold pouring stream is used to reduce turbulence braked a magnetic field acting between the broad sides of the continuous casting mold and aligned.
- To generate the magnetic field are on copper plates the broadside of the continuous casting mold Ferromagnetkeme attached, the be excited by surrounding coils.
- the caused by the magnetic field Deceleration and alignment of the pouring jet causes a calming of the Steel bath and a reduction of turbulence within the steel bath with the aim of uniform casting of steel strands.
- From DE 198 07 842 A1 is a continuous casting with an electromagnetic Braking device known, which consists of at least one of the Kokillenbreitrise associated coil having a ferromagnetic core and at least consists of a yoke associated with this. At least some parts of the electromagnetic brake device are the main components of the continuous casting mold.
- the magnetic field generated by the electromagnetic brake device is in at least one upper and one in relation to the continuous casting mold divided lower magnetic field.
- At least the inside of the electromagnetic Cores also forms cooling chambers, via the cooling water supply and the cooling water drainage he follows.
- Object of the present invention is the arrangements described above from electromagnetic brakes to continuous casting molds, in particular the tendency to tilt due to the axial feed through a carriage or carriage guide with a lot of space and weight required Avoid and retrofit, for example, in existing continuous casters to facilitate or facilitate.
- the solution of the problem is in the design of an electromagnetic Brake according to the preamble of claim 1, characterized in that the electromagnetic Braking device, consisting of yoke, current-carrying coil and ferromagnetic core in or on the continuous casting mold by at least an adjustment is turned on or swung out. Preferably takes place the mechanical pivoting in or out of the brake at least by means two unequal length, not parallel levers. This will despite existing Roadway carrier for the distribution gutter the prerequisite for a optimal retrofitting of existing plants with the invention Brake device created.
- the Brake consisting of yoke, current-carrying coil and ferromagnetic Core is not oscillatable together with the continuous casting mold.
- the inventive measures is advantageously achieved, that the electromagnetic brake is independent of the continuous casting mold, Therefore, it is easier to replace and that the oscillating masses on the Components of the continuous casting mold remain restricted and not additional masses the components of the electromagnetic brake must oscillate with.
- the working position the electromagnetic brake by a mechanical stroke limitation is designed adaptable to the mold or that their working position adjustable stroke limits is determined. It is also proposed that whose rest position is determined by means of at least one stop.
- the electromagnetic brake is by means of two unequal length, non-parallel levers 9, 10 to be attached to the carriage 11 and a carrier Adjustment 6, for example, a hydraulic cylinder, centrally to steer.
- a carrier Adjustment 6 for example, a hydraulic cylinder
- Fig. 1 shows the electromagnetic brake in the working position. In the working position an adjustable stroke limiter 8 determines the Position.
- Fig. 2 shows the rest position of the electromagnetic brake. In the Rest position is the brake on the stops 4.
