FIELD: metallurgy.
SUBSTANCE: invention refers to metallurgy. Method involves feed of molten titanium or titanium alloy into crystalliser and drawing an ingot down during hardening. Thickness of hardened ingot shell in the contact area (16) between casting mould (2) and ingot (11) is maintained within predefined range by controlling temperature (TS) of a site (11a) in contact area (16) and/or by transient heat flow (q) from site (11a) towards casting mould (2). Mean temperature of ingot surface site in the contact area is set within 800 °C<TS<1250 °C range.
EFFECT: improved quality of ingot surface.
