FIELD: metallurgy, namely metal casting in machines for blank continuous casting. SUBSTANCE: mold includes copper working walls and lengthwise trapezoidal cross section cooling ducts. Large base of trapezium is turned to working surface of wall and it is parallel relative to it. Ratio of width of large base of trapezium to its height is equal to 0.3-3.0. EFFECT: enhanced productive capacity of machine, efficiency of cooling, increased strength of mold. 2 cl, 3 dwg
