FIELD: metallurgy, applied for production of thin ingots. SUBSTANCE: has water-cooled walls on the narrower sides that can be squeezed between the walls on the wider sides. The walls on the wider sides have at least three cooled segments located one near another and independent of one another, symmetrically separated relative to the middle axis of the mould and having in the zone of the mould mouth separate connections for independent supply of coolant. EFFECT: simplified and reliable transfer of temperature in mould width at casting at a rate of 1.5 to 8 m/min. 3 cl, 2 dwg
