Abstract
This report describes inductoslag melting, an induction melting process which utilizes a split, water-cooled copper crucible and a cover of molten calcium fluoride slag. Equipment and techniques for melting ingots as large as 5 inches in diameter and 45 inches long are described. A comparative evaluation is made of ingots prepared from vacuum-distilled titanium sponge by vacuum arc melting and by inductoslag melting. The main advantage of inductoslag melting is that loose titanium sponge or scrap can be melted without fabricating a consumable electrode. While this process has some disadvantages compared to vacuum arc melting, sound ingots can be prepared by a single melt of clean titanium alloy scrap or vacuum- distilled titanium sponge. Ingots prepared by inductoslag melting have been forged and rolled to plate without machining the side walls.
