Developed and tested by the authors of technological process for producing complex profile castings of superalloy KHN57KVYUTMBRL by combined casting method of the lost-wax (gating system) and of burns polystyrene models in the shell molds of complex modified ceramics, which reduces cracking form at the expense of a correctly selected time-temperature regime annealing form with model. Also it allows you to get of casting complex profile with minimizing allowance for machining parts, to increase their geometric accuracy and reduce roughness.
