Document Type and Number:
Japanese Patent JPS6322907
Kind Code:
B2
Abstract:
An electromagnetic inductor for generating a helically moving magnetic field includes a first magnetic circuit having an annular core with radially inwardly projecting teeth and a winding for generating a rotating magnetic field, and a second magnetic circuit formed by foliated bars and a second winding comprising an axial series of circular coils for generating an axially moving field. The two fields combine to generate a field with helical movement. At least some consecutive teeth of the core are hollowed to provide axial grooves in which the foliated bars are disposed. The coils of the second winding are cylindrical and set inside the cylindrical volume defined by the teeth. The inductor is particularly adapted for the electromagnetic rabbling of a billet in a continuous casting process.
