description: The purpose of the work was to develop and implement proposals to combat defects in shrinkage defects of casting from high-strength cast iron made of highâstrength cast iron with spherical graphite ASTM A395 on the example of casting for a part of the stator cold part of the gas turbine GPA - 32 "Ladoga" for PJSC Gazprom. The collection and mathematical modeling were carried out, in the program "PoligonSoft", according to the quality of the casting. It is established that the fluctuations in the casting temperature in various smelts are insignificant and, therefore, it does not significantly affect the degree of damage to castings by shrinkage defects. A preliminary conclusion has been made about the predominant influence of the design of profits on the quality of castings and the need for their improvement. Proposals for improving the profit system in terms of changing hollow profits to exothermic inserts have been developed and pre-tested in the modeling process. As a result of the implementation of the developed proposals, a casting was obtained in which there are completely no degrees of damage by shrinkage defects, which makes it possible to reduce allowances for machining, the cost of eliminating (cutting and welding) defects, Increase the yield of suitable casting, reduce the mass of the metal consumed by the mold.
