Abstract: A method and a device for continuous or semi-continuous casting of metal. A primary flow (P) of hot metallic melt supplied into a mold is acted upon by at least one static or periodically low-frequency magnetic field to brake and split the primary flow and form a controlled secondary flow pattern in the non-solidified parts of the cast strand. The magnetic flux density of the magnetic field is controlled based on casting conditions. The secondary flow (M, U, C1, C2, c3, c4, G1, G2, g3, g4, O1, O2, o3, o4) in the mold is monitored throughout the casting and upon detection of a change in the flow, information on the detected change monitored flow is fed into a control unit (44) where the change is evaluated and the magnetic flux density is regulated based on this evaluation to maintain or adjust the controlled secondary flow.

Date Oct. 31, 1996A furnace plant which at least one furnace vessel with side walls and a bottom and at least one heat source which by radiation and convection heats molten metal and/or solid metal present in the furnace vessel. At least one two- or multiphase electromagnetic side stirrer is arranged in or near the wall of the furnace vessel to act through the wall and apply a stirrer field to the molten metal. The side stirrer comprises at least two phase windings arranged around an iron core having a vertical extent, H, which essentially covers the region, Dmax, between the bottom and the upper surface of the molten metal at a maximum bath depth used in the furnace 15 vessel. The side stirrer is arranged with a pole pitch tau which exceeds twice the distance from the iron core to the molten metal, tau >2 dw.

Abstract: A device and a method for stabilising a metallic object of magnetic material. The metallic object is transported along a transportation path or plane. The plane includes a transportation direction and is parallel to the longitudinal direction of the object therein. A sensor is arranged to sense the valve of a parameter depending on the position of the object with respect to the plane. An electromagnetic actuator is arranged to apply a magnetic force to the object in respone to the sensed position. The magnetic force has a force component directed transversely to the transportation direction and transversely to the plane.

Abstract: A method and a device for continuous casting of metals, in which the device comprises a mould (1), through which a liquid metal passes, and a member (4), through which a liquid metal is supplied as a jet to the mould (1). The device comprises magnet members (6, 7) for applying a magnetic field varying with time and being substantially fixed in the room to the liquid metal in the mould (1).
