METHOD FOR MAGNETIC FLUX COMPENSATION IN A DIRECTIONAL SOLIDIFICATION FURNACE UTILIZING A STATIONARY SECONDARY COIL

METHOD FOR MAGNETIC FLUX COMPENSATION IN A DIRECTIONAL SOLIDIFICATION FURNACE UTILIZING A STATIONARY SECONDARY COIL

A process for directional solidification of a cast part comprises energizing a primary inductive coil (20) coupled to a chamber (12) having a mold (16) containing a material (24); energizing a primary inductive coil (20) within the chamber (12) to heat the mold (16) via radiation from a susceptor (2...

Zusammenfassung:A process for directional solidification of a cast part comprises energizing a primary inductive coil (20) coupled to a chamber (12) having a mold (16) containing a material (24); energizing a primary inductive coil (20) within the chamber (12) to heat the mold (16) via radiation from a susceptor (26), wherein the resultant electromagnetic field (28) partially leaks through the susceptor (26) coupled to the chamber (12) between the primary inductive coil (20) and the mold (16); determining a magnetic flux profile of the electromagnetic field (28); sensing a magnetic flux leakage (44) past the susceptor (26) within the chamber (12); generating a control field (42) from a secondary compensation coil (40) coupled to the chamber (12), wherein the control field (42) controls the magnetic flux (44) experienced by the cast part; and casting the material (24) within the mold (16) under the controlled degree of flux leakage (44).
