Abstract:
A magnetic brake, arranged for use for casting of two strands in parallel in a chill mold, which has a rectangular casting mold with an inner partition subdividing the rectangular casting mold into two sub-molds, said brake having a first magnet arranged at a first long-side of the rectangular casting mold, and a second magnet of opposite polarity arranged at the opposite second long-side of the rectangular casting mold, wherein magnetic material of each of said first and second magnets is distributed into two magnetic sub-poles of the same polarity arranged adjacent to each other along each of the first and second opposing long-sides of the rectangular casting mold and both sub-poles are symmetrically arranged along the long-side of a respective sub-mold to generate and apply at least one static or periodic low frequency magnetic field with essentially the same magnetic field direction across the entire width of the rectangular casting mold, and with an essentially symmetrical distribution in both the sub-molds.
