发明名称 A METHOD AND DEVICE FOR CONTROLLING STIRRING IN A STRAND
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).
