Electromagnetic braking device for continuous casting mold and method of continuous casting by using the same

摘要

In a magnetic brake apparatus for a continuous casting mold having a pair of first and second upper electromagnets 17A and 17B which are oppositely placed near the rear faces of the opposing side walls of the continuous casting mold 10, and a pair of first and second lower electromagnets 21A and 21B which are oppositely placed thereunder, a static magnetic field being generated between each pair of electromagnets to stem the stream of the molten steel supplied to the casting mold by the static magnetic field, the apparatus has controlling units which independently control a current supplied to magnetic coils 16A and 16B being constituents of the first and second upper electromagnets and a current supplied to magnetic coils 20A and 20B being constituents of the first and second lower electromagnets. The intensity of the magnetic field between the magnetic poles of the upper and lower electromagnets can, thereby, be readily and inexpensively varied during casting without restriction. IMAGE
