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

METHOD FOR MAGNETIC FLUX COMPENSATION IN A DIRECTIONAL SOLIDIFICATION FURNACE UTILIZING AN ACTUATED 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); generating an electromagnetic field (28) with the primary inductive coil (20) within the chamber (12), wherein said elec...

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); generating an electromagnetic field (28) with the primary inductive coil (20) within the chamber (12), wherein said electromagnetic field (28) is partially attenuated by a susceptor (26) coupled to said chamber (12) between said primary inductive coil (20) and said mold (16); determining a magnetic flux profile (44) of the electromagnetic field (28) after it passes through the susceptor (26); sensing a component of the magnetic flux (44) in the interior of the susceptor (26) proximate the mold (16); positioning a mobile secondary compensation coil (40) within the chamber (12); generating a control field (42) from the secondary compensation coil (40), wherein said control field (42) controls said magnetic flux (44); and casting the material (24) within the mold (16).
