ABSTRACT:
A method of magnetically-controllable, electroslag melting of titanium and titanium-based alloys is provided that includes the effect of an external radial magnetic field on the metallurgical melt. The field forms at least two adjoining melting layers which are rotated horizontally in opposite directions, and causes intralayer and meridional toroidal rotation of the melt. The uniform hydrodynamic structure of the melt over the total length of the ingot is stabilized by changing the melting voltage. The external radial magnetic field and the use of a fluoride-chloride flux improves the refinement of metal (by reducing harmful inclusions), condenses the metal structure, and provides high chemical and physical homogeneity of the metal ingot.
