METHOD OF PREPARING THE FROZEN PATTERNS

摘要

Invention relates to the foundry production of ferrous and nonferrous metals. The method of preparing the frozen patterns includes the filling of liquid composition with high-molecular surfactant into the mold; mixing of gas and freezing this composition, moreover mixing and freezing are performed by blowing of the cooled gas through the liquid composition. Invention allows to decrease the quantity of pattern materials and to reduce the time of production of patterns.
