FIELD: metallurgy.
SUBSTANCE: invention can be used for production of ingot of tool steel during electroslag remelting in inert gas or under pressure. Crystallizer comprises an inner copper sleeve of elliptic geometric shape with width w 1000–2500 mm and thickness t 700–1250 mm, wherein short sides in direction of thickness of copper sleeve at least partially have sections with curved surfaces, and long sides in direction of copper sleeve width at least partially have sections with curved surfaces.
EFFECT: invention enables to form a crystallizer for production of large ingots with improved purity and/or microstructure.
