FIELD: ferrous metallurgy. SUBSTANCE: ingot mould has areas transient between the borders and limited by the curvilinear surface formed by two radius conjugated by a plane or by three radius. The middle area is directed opposite to the areas on the ends and is bent in the inner cavity of the ingot mould. The radius values of the areas on the ends make up 10%, and of the middle area - 15. ..20% of the inner width of the ingot mould in its middle part. EFFECT: facilitated manufacture. 2 dwg
