Application Effect of Electromagnetic Brake in Continuous Casting Mold

The using effect of Flow Control Mold Electromagnetic Brake(EMBR) at 2# continuous caster in Meishan Steel was studied.It shows that with increasing of the current strength,the magnetic field intensity is intensified and the flow field in mold is changed.The magnetic field intensity in lower mold is 0.34～0.45 T when the current of lower coil is 800~850 A.When the current of upper coil increases to 400 A from 200 A,the magnetic field intensity in upper mold increases to more than 0.3 T from 0.2 T.With the using of EMBR,the height variation of molten steel in mold is decreased obviously,the temperature of molten steel in mold increases about 10 ℃,the inclusion amounts in molten steel are less and their diameters are smeller,the biggest diameter is under 20 μm.but slag entrapment still occurs,so EMBR controlling technology should be studied further.
