| Summary: | It is shown that the main technological problems of modifying of structure of silumin castings are: absence of the universal modifiers, limitation of their action in time; saturation of a melt by hydrogen and oxide of silicon. Admixture modifiers do not solve these problems. These problems could be solved by method of hereditary modifying. For this purpose it is necessary to use the silumin castings with a high-dispersible microstructure received by casting in a crystallizer with a high speed of cooling. |
