A casting mold including a copper plate and a plurality of optical fibers, having a plurality of temperature measuring points for the copper plate while casting. Molten metal is cast into the mold along an axis of, the optical fibers built-in the plate. A method for detecting temperature distribution of a molten metal in a casting mold having at least one copper plate, including determining by calculation or measurement an ideal molten flow of the metal, building-in a plurality of optical fibers into the copper plate based on flow, arranging the optical fibers inside at least the upper part of the copper plate, receiving the measurements of temperatures, and comparing the measurements of temperatures with a calculated/measured distribution of an ideal molten flow.

A system and a method for determining/predicting a tapping time for a metal melt in an electric arc furnace (EAF), at least one electrode is provided for melting the metal melt until it reach a target tapping temperature, the EAF further includes a slag and smoke layer on the surface of the metal melt, wherein an electromagnetic stirrer is provided for stirring the metal melt.

A device for stabilizing an elongated steel sheet when continuously transporting the steel sheet in a transport direction along a predetermined transport path. The device includes at least a first pair, a second pair and a third pair of electromagnets with at least one electromagnet on each side of the steel sheet. The electromagnets are adapted to stabilize the steel sheet with respect to the predetermined transport path. The first and second electromagnets are elongated in a direction essentially perpendicular to the transport direction. The first and second electromagnets are substantially arranged on each side of a longitudinal center line for the steel sheet. The center line is essentially parallel to the transport direction. The third electromagnet is arranged adjacent to the center line.

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

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.
