Study on Metallurgical Effects of M- EMS during Bloom Continuous Casting

In this paper,M-EMS magnetic field intensity and bloom quality at different periods is counted,and on this basis,the effect of magnetic field intensity of M-EMS on casting bloom quality is analyzed.Different magnetic field intensity in a single strand can be obtained by changing the current intensity of M-EMS.Then,the corresponding bloom under different magnetic field intensity are sampled for testing.Thus,the effect of magnetic field intensity on bloom quality is studied in a single strand.Analysis suggests that M-EMS should not be used when its magnetic field intensity is less than 300×10-4 T.Furthermore,the metallurgical effects of bloom M-EMS in Pangang are evaluated and the applicable standard for M-EMS is established.
