    摘要: A device for slowing down the non-solidified portions of a cast strand during continuous casting of billets or blooms. The device comprises a group of at least three separate molds (1-4) which are open in the direction of casting and which are arranged such that each one is supplied with a flow of melt. The device also comprises a number of magnetic core parts (5-8), and at least one magnetic-field generating member (9-13), adapted to generate and transfer, together with the magnetic core parts, a static magnetic field or a periodic low-frequency magnetic field to the inflowing melt in such a way that the movement of the melt is slowed down. The magnetic core parts and the magnetic-field generating members are arranged such that, together with all the molds in the group, they form a common closed magnetic circuit. All the molds included in the group are arranged in series with each other in the closed magnetic circuit.

    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.
