induction melting process using segmented graphite

NIOSHTIC

Inductoslag melting is an induction melting technique using a segmented, water- cooled, copper crucible. The process was developed as part of the Bureau's work on effective utilization of reactive metal scrap, and the process has been applied to melting ti, zr, cr, CO, fe, ni, and V. Construction details are given for the segmented crucibles and for both an ingot furnace and a casting furnace.

Smelting

Inductoslag melting is an induction melting process utilizing a segmented, water-cooled copper crucible. The crucible is segmented to prevent attenuation of the field of the induction coil, and a salt, such as CaF2, is added to the crucible during melting to electrically insulate the crucible segments from the molten metal.
