Abstract:Abstract:For the improvement horizontal continuous casting round billet's internal quality, developed S+F-EMS technology independently, under the contrastive analysis same level working condition casts the semifinished product macrostructure result to indicate that cast the semifinished product center equiaxed crystal distinct enhancement after the electromagnetism agitation, the middle crack, the center porosity, flaw ranks and so on central crack reduced obviously. Applies other units this new technology, after electromagnetism agitation parameter optimization, further enhanced has cast the semifinished product center equiaxed grain rate, to develop the high alloying element content aluminum to lay the foundation.
