In a mold for the continuous casting of flat metal products with a submerged nozzle having lateral outlets, said mold being equipped on each of its long sides 3 with a pair of linear inductors generating a magnetic field that travels horizontally over the width of said long side and are placed on either side of the casting nozzle 5 , this method for adjusting the stirring mode is characterized: in that, since the inductors 10 a to 11 b are mounted in pairs so as to slide vertically over the height of the mold, said inductors, by being moved, pass from a low stirring position LP for assistance to the incoming jets of liquid metal, located level with the outlets 17 of the nozzle, to a high stirring position HP for making the cast liquid metal rotate about the casting axis, located level with the meniscus 9 of the liquid metal in the mold, and vice versa; and in that, on passing from one position to the other, the connections for the inductors to the phases of the power supply 7 are modified so as to reverse the direction of travel of the magnetic field of only one of the two inductors of any one pair and also that, among the two inductors of the other pair, which is symmetrical with respect to the casting axis.
