Shrinkage prediction of graphitic cast iron
Blažek, Petr ; Kaňa, Václav (referee) ; Krutiš, Vladimír (advisor)
The thesis deals with the shrinakage prediction of graphitic cast iron. In the theoretical part, volume changes and influences on graphene expansion are described in detail. Furthermore, pouring methods and simulation parameters related to schrinkage and pouring are broken down in the work. In the practical part, thermophysical data and metallurgical quality of the metal are optimized in the simulation. For the specified casting, the risers were designed according to theoretical methods and the simulation optimization module. Using optimized risers, it was possible to save the volume of metal per raw casting by about 25 %. For castings from the soft bentonite mold and from the mold from the GEOPOL® (a self hardening mixture), the volume was measured using a 3D scan. When they were compared, an uneven increase in the volume of the bentonite mould casting was 1.2 %. The increase was due to the strain of the mold in the graphite expansion.
