A new electromagnetic brake technology called V-EMBr(Vertical-Electromagnetic Brake)which was applied in slab continuous casting process was put forward.The three-dimensional magnetic field and flow field model for describing the slab continuous casting process with V-EMBr were established and solved by commercial software Ansys and fluent
then the distribution of the magnetic flux density and flow velocity in mold was visualized and analyzed.The characteristics of magnetic flux density and the flow velocity variation in mold with V-EMBr were described.The calculation results reveal that the constant magnetic field generated by V-EMBr can cover the molten steel region near the mold narrow face and the height region from free surface to the impact point of the main jet
and the magnetic flux density is mainly in magnetic pole covered area
outside the magnetic pole covered area
and a decaying magnetic field distribution of magnetic flux density is observed in molten steel.After applying the V-EMBr
the impact velocity of the main jet
molten steel velocity of free surface and the impinging depth in lower recirculation zone are decreased significantly
which are beneficial to reducing slag
preventing breakout and promoting inclusions floating
and then improving the quality of the slab.Thereby
the V-EMBr shows the satisfied metallurgical effect.
