FIELD: metallurgy, namely, continuous casting. SUBSTANCE: mold includes square- or rectangular-shaped sleeve open at both sides. Upper funnel-like portion of sleeve has four walls with convexity and straight lateral portions. Height of sleeve inner cavity smoothly decreases from its maximum value in upper portion of sleeve until zero in lower shaping portion of sleeve. Inner cavities are in the form of equilateral curvilinear trapeziums with straight upper base and curvilinear lateral sides smoothly joined with flat portions near angles. EFFECT: lowered deformation values in angles of solidified skin of cast billet. 5 cl, 6 dwg
