Abstract
Currently, there is a significant demand for cast parts, requiring no further machining, especially true for complex cavities of high quality. On the one hand, it is impossible to obtain the necessary quality with sandy clay rods without subsequent machining, on the other hand, the machining is difficult because it is impossible to bring the tool work surface.In this article the complicated technology of obtaining cavities with metal rods cooled quality is considered. This approach allows you to adjust the intensity of the cooling rod, and, consequently, the casting, which gives us additional leverage to produce quality castings.The article also discussed method of calculating the required time "cake frosting" in the manufacture of a metal rod, the optimum thickness of the thermal barrier coating and the cooling of the rod.Such technology can be used in the manufacture of pistons cooled internal combustion engines, hydraulic equipment, etc
