Abstract RU 2043855 C1

FIELD: foundry. SUBSTANCE: method to produce casting with ordered structure includes fabrication of shell mold, mold heating up to the temperature above liquidus temperature of high temperature steel, filling the mold with melt and ordered crystallization. In so doing, crystallization is provided with granulated high-melting alloy located in the bottom of the casting mold. The material is heated up to the temperature lower than melting point of the granules, and its shape is the same as one of casting end being in contact with the material. Powder tungsten/nickel alloy may be used as high-melting material. EFFECT: high productivity and accuracy. 2 cl
