DEVICE FOR CONTINUOUS CASTING OF TWO STRANDS IN PARALLEL

摘要

A magnetic brake, which for casting of two elongate strands in parallel generates at least one static or periodic low frequency magnetic field. The chill mold has a rectangular casting mold (10) with an inner partition (13) which subdivides the rectangular casting mold into two sub-molds (11a, 11b) and the magnetic field acts with essentially the same magnetic field direction across the entire width of the rectangular casting mold, and has an essentially symmetrical distribution in the both sub-molds. The brake has a first magnet at a first long-side of the rectangular casting mold and a second magnet of opposite polarity at the opposite second long-side of the rectangular casting mold. The magnetic material in the magnets is such distributed, that both magnets each have two magnetic sub-poles of the same polarity arranged adjacent to each other along each of the two long-sides of the rectangular casting mold. Each sub-pole is symmetrically arranged along the long-side of the respective sub-mold.
