Abstract (en)

[origin: FR2772294A1] The invention concerns an electromagnetic braking device consisting of an electric power supply and an electromagnetic inductor with multiple windings (1) such as a "polyphase stator of a linear motor with sliding magnetic field" designed to be mounted opposite one surface of a cast product, in particular at the large wall (14) of an ingot mould casting steel slabs (12), and comprising windings (A, B) connected with the electric power supply. The latter consists of a plurality of elementary powering units (8, 9) supplying direct current each provided with its own particular means (10, 11) for regulating the current intensity delivered, each of said windings (A, B) of the inductor capable of being connected to one of said elementary powering units (8, 9) on its own. The equipment enables to localise the braking action in the ingot mould at any one moment, even during casting, without having to modify the position of the inductor.
