ABSTRACT:
A continuous casting method for the production of a casting having a solidified metallic structure which is nearly all composed of equiaxed crystal uniformly distributed, by agitating the crater of the cast object during the process of solidification by applying a travelling electromagnetic field to an extent sufficient to make the velocity vector of the main flow of the agitated molten metal present in the plane perpendicular to the direction of withdrawing the cast object and to confine the entire flow in such crater within the limited agitation zone, and an apparatus for carrying out the method.
