US 2019/0127882 A1 · SEPARATE VESSEL METAL SHIELDING METHOD FOR MAGNETIC FLUX IN DIRECTIONAL SOLIDIFICATION FURNACE

Abstract

An induction furnace assembly comprising a chamber having a mold; a primary inductive coil coupled to the chamber; a susceptor surrounding the chamber between the primary inductive coil and the mold; and a shield material contained in a reservoir coupled to or proximate the mold between the susceptor and the mold; the shield material configured to attenuate a portion of an electromagnetic flux generated by the primary induction coil that is not attenuated by the susceptor.

Dependent claims

A process for directional solidification of a cast part comprising:

energizing a primary induction coil within a chamber having a mold containing a material;
generating an electromagnetic field with the primary induction coil within the chamber, wherein said electromagnetic field partially leaks through a susceptor coupled to said chamber between said primary induction coil and said mold;
controlling a component of a magnetic flux leakage with a shield material coupled to the mold;
and
casting the material within the mold.
