ABSTRACT:
An apparatus for providing a magnetic field in a casting mold to slow and redirect in a controllable fashion the flow of liquid steel exiting a submerged entry nozzle in the casting mold using removable laminar elements arrangeable in a horizontal series of vertical stacked arrays in association with corresponding side-by-side laminar constituents of the magnetic field core, or independent field coils for energizing each laminar portion of the magnetic field core, or both. The removable elements are preferably stackable rectangular parallelepiped plates together forming selectably a portion or all of the poles of the core as they extend into proximity with the transverse mold sides at selected locations.
