Preparation of Ingots and Shaped Castings by Inductoslag Melting.
Proc 5th Internat Symp on Electroslag & Other Special Melting Techs 1975 Mar; :477-96
Inductoslag melting is an induction melting technique that utilizes a segmented, water-cooled copper crucible. The crucible walls are segmented to prevent attenuation of the field of the work coil by the metal walls of the crucible. Calcium fluoride, added to the crucible with the metal to be melted, forms a thin coating on the cold wall of the crucible and electrically insulates the crucible segments from the molten metal. Ingots up to 5 inches in diameter were melted with the 100-kilowatt, 10-kilohertz power supply available. Shapes castings were produced by inductoslag melting in a 5-inch-diameter ladle that provided a maximum of 7 to 8 pounds of molten titanium for casting.
