PLANT FOR CONTINUOUS CASTING OF INGOTS PRODUCED OF TITANIUM OR TITANIUM ALLOY Russian patent published in 2017 - IPC B22D11/41 B22D11/11 

FIELD: metallurgy.

SUBSTANCE: plant comprises a mould (2) with a circular cross section, from which a solidified ingot is drawn down, and plasma burners (7a, 7b) located on the side of melt surface (12) in a crystalliser. During casting, the burners (7a, 7b) are moved in horizontal direction above the melt surface along a path providing arrangement of burners (7 a, 7b) from each other at a distance preventing their mutual influence. The movement path of the burner includes a arc of inner circumference with radius r1 from center of melt surface, arc of outer circumference with radius r2 from center of melt surface and a straight line connecting said arcs of inner and outer circumference, wherein 0<r1<R/2 and R/2<r2<R r/2, where R is radius of the melt surface.

EFFECT: increasing the quality of the casting surface and increasing the service life of the plasma burners.
