<p>An electromagnetic braking device for continuous casting mold provided near the backs of the facing side walls of the mold (10) with a pair of first and second upper electromagnets (17A and 17B) oppositely arranged on both sides of a continuous casting mold (10) and a pair of lower electromagnets (21A and 21B) oppositely arranged below the electromagnets (17A and 17B) for braking a molten-steel flow supplied to the mold (10) by utilizing a static magnetic field generated between each paired electromagnets. This device is provided with a controller which independently controls the electric currents supplied to the electromagnetic coils (16A and 16B) constituting the first and the second upper electromagnets (17A and 17B) and to the electromagnetic coils (20A and 20B) constituting the first and the second lower electromagnets (21A and 21B). Therefore, the intensities of the magnetic fields respectively formed between the magnetic poles of the upper and the lower electromagnets can be changed easily and inexpensively and, moreover, arbitrarily during casting.</p> |
