FIELD: casting. SUBSTANCE: blank has a capsule with an article moldable material, end covers, primary members one of which is made in the form and profile of the article, and the second one - in the form of an article cooling tubular member with shaped working surface profile, and of diameter 0.10-0.25 of the maximum height of the profile. The second member is positioned in the moldable material at a distance from the first primary member equal to 0.5-3.0 of the diameter of the tubular member. The ratio of the area of the tubular member surface to the area of the working surface of the article is equal to 0.10-0.55. A heat-resistant difficultly deformable alloy is used as the moldable material. EFFECT: improved structure. 1 tbl, 1 dwg
