ABSTRACT:
A method of magnetically-controllable, electroslag melting of titanium and titanium-based alloys which provides high homogeneity over substantially the total ingot length is provided. The homogeneity of the ingot is achieved by maintaining the maximum permissible values of electrode gap and consumable electrode feed rate substantially constant. The value of the melting current increases due to the decreasing melting voltage. The direction and intensity of magnetically-controllable, toroidal rotation are kept substantially constant by maintaining the melting current and electrode gap at substantially constant values. The quality of the metal was increased due to the reduction of harmful gas inclusions by using the fluoride-chloride flux. This metal purification is optimized by the toroidal rotation of melt. Smooth regulation of the melt direction is provided by using the device for stabilizing the melting current.
