Claim Text:
1. A process for controlling the flows of liquid metal in a continuous casting of thin slabs, wherein there are provided: a crystallizer ( a discharger ( a first electromagnetic brake ( a second electromagnetic brake ( a third electromagnetic brake ( a fourth electromagnetic brake ( a fifth electromagnetic brake ( wherein each of said electromagnetic brakes comprises a pair of magnetic poles symmetrically arranged with respect to symmetry plane of said crystallizer, which is substantially parallel to opposite front walls of said crystallizer, each magnetic pole comprising a core and a respective coil supplied by direct current, said core of each magnetic pole being physically independent from the cores of the other electromagnetic brakes, said magnetic poles being configured, so as to generate a magnetic field which crosses said bath according to directions substantially orthogonal to said front walls of said crystallizer, said apparatus comprising a pair of reinforcing walls, each externally adjacent to one of said front walls of said crystallizer, said apparatus comprising a pair of ferromagnetic plates each arranged parallel to one of said reinforcing walls so that the magnetic poles, arranged on a same side with respect to said symmetry plane are comprised between one of said reinforcing walls and one of said ferromagnetic plates wherein said process includes activating said braking zones ( 10 , 11 , 12 , 13 , 14 , 15 ) either independently or in groups according to characteristic parameters, of the fluid-dynamic conditions of said liquid metal in said bath ( 4 ).
