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