    • A chill mold for the simultaneous casting of two parallel strands and a magnetic brake which generates at least one static or periodic low frequency magnetic field. The chill mold includes a rectangular casting mold and an inner partition which subdivides the rectangular casting mold into two sub-molds, 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 both sub-molds. The brake includes 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 first and second magnets is distributed such that both magnets 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.
    • 用于同时铸造两根平行线的冷却模具和产生至少一个静态或周期性低频磁场的磁性制动器。 冷却模具包括矩形铸模和将矩形铸模分为两个子模具的内分隔件,并且磁场在矩形铸模的整个宽度上基本上具有相同的磁场方向,并具有基本上对称的 分布在两个子模具中。 制动器包括长方形铸模的第一长边处的第一磁体和在矩形铸模的相对的第二长边处具有相反极性的第二磁体。 第一和第二磁体中的磁性材料分布成使得两个磁体具有沿着矩形铸模的两个长边中的每一个彼此相邻布置的具有相同极性的两个磁极。 每个子极沿对应的子模具的长边对称地布置。
