摘要： PROBLEM TO BE SOLVED: To provide a method for controlling a flow of molten steel in a mold by applying at least one magnetic field to the molten steel in a continuous slab casting machine.SOLUTION: This is achieved by comprising controlling a molten steel flow velocity on a molten steel bath surface, meniscus 9, 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 4 when the molten steel flow velocity on the meniscus is higher than a mold powder entrainment critical flow velocity and by controlling the molten steel flow velocity on the meniscus 9 to a range of from an inclusion adherence critical flow velocity or more to a mold powder entrainment critical flow velocity or less by applying a shifting magnetic field 7 to increase the molten steel flow when the molten steel flow velocity on the meniscus 9 is lower than the inclusion adherence critical flow velocity.

摘要： A method of controlling the flow of molten metal in non-solidified portions of a strand (3) during continuous casting, and a device for application of the method. The device comprises a two-phase or plural-phase stirrer (1) arranged around a mould (6) that is open in opposite ends and that surrounds the strand (3), said stirrer (1) being arranged to generate a moving magnetic field in the melt, and at least one magnetic flow-conducting body (15) being placed between an inner periphery of said stirrer (1) and the outer periphery of the mould (6). In the case of open casting, the magnetic flow-conducting body (15) is positioned in a first position in which it displaces at least a part of the magnetic flow generated by the stirrer (1) in a direction towards the meniscus (17) of the strand (3), and, in the case of closed casting, the magnetic flow-conducting body (15) is positioned in a second position in which it displaces at least a part of the magnetic flow generated by the stirrer (1) away from the meniscus (17) of the strand (3).

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： A device for continuous or semi-continuous casting of metal has a cooled continuous casting mold assembly and an inductive coil arranged at the top end of the mold assembly. The mold assembly is divided into at least two mold assembly parts separated and electrically insulated from each other by partitions, which are oriented in the casting direction and where each partition is formed with an electrically insulating barrier. Each mold assembly part has a mold part associated with a corresponding mechanically supporting mold back-up structure part, and an electrical conductor, with an electrical conductivity higher than the electrical conductivity of the back-up structure. The conductor is arranged with the mold back-up structure part on the side of the mold back-up structure part facing away from the mold, the outside face.
