    摘要: A device for continuous or semi-continuous casting of metal comprising a cooled mold (22) and an induction coil (10) arranged at the top end of the mold. The mold comprises in its top end a plurality of hollow, old segments (22a, 22b, 22c, 22d, 22e, 22f, 22′b, 22′c, 22′d) separated from each other by partitions (26a, 26b, 26c, 26d, 26e), which all comprise an electrically insulating barrier. Both the mold segments and the partitions are oriented essentially in the casting direction. Each hollow top end mold segment comprises a core of a mechanically supporting bar or beam (25a, 25b, 25c, 25d, 25e, 25f, 25′a, 25′b, 25′c, 25′d, 25′e, 25′f) arranged within the hollow mold segment such that it is surrounded by the hollow mold segment. The core exhibits superior mechanical properties in relation to the mold.

    摘要: Method for controlling a flow of molten steel in a mould by applying at least one magnetic field to the molten steel in a continuous slab casting machine. Controlling a molten steel flow velocity on a molten steel bath surface to a predetermined molten steel flow velocity by applying a static magnetic field to impart a stabilizing and braking force to a discharge flow from an immersion nozzle when the molten steel flow velocity on the meniscus is higher than a mould powder entrainment critical flow velocity. Controlling the molten steel flow velocity on the meniscus to a range of from an inclusion adherence critical flow velocity or more to a mould powder entrainment critical flow velocity or less by applying a shifting magnetic field to increase the molten steel flow when the molten steel flow velocity on the meniscus is lower than the inclusion-adherence critical flow velocity.

    摘要: A device for continuously manufacturing a cast strand by continuous casting of liquid metal melt wherein the flow of the liquid metal in the non-solidified portions of the strand is controlled by means of a static or periodic low-frequency magnetic field. A mould adapted to be supplied with the melt includes copper plates (2a,2b) which form a casting mould space with a rectangular cross section, water box beams (3) which are arranged outside the copper plates to support and cool them, and a member (4) holding the mould together. Magnetic field-generating devices, i.e., magnets, are provided close to the mould to generate a static or periodic low-frequency magnetic field which acts in the path of the inflowing melt and divides the primary flow as well as checks any secondary flows arising. Each magnet comprises a front core (5), a rear core and a coil (7). The front core is a fully integral part of the water box beam and the rear core comprises a rear movable part (6b) which is movable in a direction which substantially coincides with the direction of the field.
