STIRRING METHOD AND ITS DEVICE AND ELECTROMAGNET IN MOLD OF HORIZONTAL CONTINUOUS CASTING

STIRRING METHOD AND ITS DEVICE AND ELECTROMAGNET IN MOLD OF HORIZONTAL CONTINUOUS CASTING

Automagnetic stirring is effected within the mold of a horizontal continuous casting appts. An electromagnetic coil is disposed around the mold and a magnetic field is induced by an alternating current with a frequency f of 1-15Hz. The max. magnetic flux density is within the range from 1045e-0.16f...

Zusammenfassung:Automagnetic stirring is effected within the mold of a horizontal continuous casting appts. An electromagnetic coil is disposed around the mold and a magnetic field is induced by an alternating current with a frequency f of 1-15Hz. The max. magnetic flux density is within the range from 1045e-0.16f to 2054e0.12f and is located at a position within 350mm from the junction between the puring nozzle and the mold in the direction of drawing of the cast piece. The occurence of surface defects such as cold short and vertical surface cracks is minimised.
