FIELD: metallurgy. SUBSTANCE: crystallizer has narrow walls with length exceeding that of wider walls and making 1.1-1.2 of its length. Narrow walls are positioned for vertical displacement and inclination relative to wide walls. Working surface of narrow walls has two flat longitudinal portions positioned in angular relation one to another. Flat portion joining line is spaced from top end of wide walls by distance equal to 0.2-0.5 of their length. EFFECT: increased efficiency and improved quality of ingots. 2 cl, 2 dwg, 1 tbl
