FIELD: foundry, possibly processes and equipment for casting products with oriented structure, mainly used as blades of gas turbine engines and gas turbine plants.
SUBSTANCE: ceramic mold includes pouring basin, runner cavity, working and starting cavities. Lower part of starting cavity includes thermally conducting member partially protruding outside mold and it is provided at least with one heat insulation partition. Relation of height of starting cavity to total height of heat insulating partition is 1 : (0.02 - 0.5). Partition is made refractory porous ceramic material and it has through openings. Mold is provided in addition with crystal sampler in order to produce articles with monocrystalline structure.
EFFECT: improved quality of cast products.
