1. Method for stirring the non-solidified portions of a cast strand extruding from a continuous casting machine, the strand is being formed in a mould (4) and the stirring being performed asymmetrically by an electromagnetic stirrer, characterized in that the stirring is performed by at least one first and at least one second stirrer, whereby said first stirrer (1) works asymmetrically by being supplied either by two phases having a mutual phase displacement differing from 90 degrees, or by three phases having a mutual phase displacement differing from 120 degrees, while the second stirrer (2) works with the same number of phases as the first stirrer but either symmetrically or with a different type of asymmetry than said first stirrer, for example with a current in one phase deviating at least 10 percent from the current in one of the other phases, or with correspondingly asymmetrically constructed phase coils. |
