Zusammenfassung:A new pouring method for Cold Crucible Induction Melting (CCIM) was developed. In this method a solidified skull is melted with a high frequency coil placed under the bottom of a crucible. Then, the molten metal is poured from a bottom copper nozzle which is segmented and water-cooled. The shape of the pouring nozzle was designed through the numerical simulation of electromagnetic and thermal fields. Titanium melting and bottom pouring were successfnlly performed with the CCIM apparatus.
