The first and second plurality of electromagnets are mutually arranged in a position mirroring the theoretical feeding plane. Each of the electromagnets includes: a core provided with at least a first and a second pole; a first and a second coil wound about the first and second poles, respectively; two power sources to supply the coils, respectively, so as to generate a first and a second magnetic field, respectively; and at least one concentrator made of ferromagnetic material connected to the core and arranged so as to make the first and the second coil magnetically independent of each other.

Abstract: The present invention relates to a process for controlling the distribution of liquid metal flows of in a crystallizer for the continuous casting of thin slabs. In particular, the process applies to a crystallizer comprising perimetral walls which define a containment volume for a liquid metal bath insertable through a discharger placed in the middle of the bath. The process includes arranging a plurality of electromagnetic brakes, each for generating a braking zone within said bath, and activating these electromagnetic brakes either independently or in groups according to characteristic parameters of the fluid-dynamic conditions of the liquid metal within the bath.

Abstract: A shield for an integrated circuit comprising an upper wall and a side wall assembly. The upper wall includes a top surface, a bottom surface and a perimeter. The side wall assembly depends from the perimeter of the upper wall. The side wall assembly has a proximal end, a distal end, an inner surface and an outer surface. The distal end defines a lower edge. At least a portion of the side wall assembly includes a plurality of surface variations along a length thereof, to, in turn, define a lower edge of the side wall assembly having a non-linear configuration. Such a non-linear configuration increases the rigidity of the shield.
