The paper considers the issues of necessity of use of mathematical simulation of the structuring process by crystallization. Performing such mathematical simulation of the casting process with directed crystallization will allow developing both the theoretical procedure for evaluation of grain of the cast structure and specify the basic requirements to the thermal and physical parameters of the...

——————————  —————————— Abstract-Simulation is now well accepted as a scientific approach to casting methoding, ensuring design process parameters, internal quality, optimal yield and short development time of casting process. Method layout involves decisions regarding part orientation in mould, parting line, cores, cavity layout, feeders, neck and gating system. An improper method layout leads...

Based on results from computational studies and plate casting trials, deficiencies in the steel casting feeding rules as currently published by the Steel Founders’ Society of America (SFSA) were determined. A methodology for the development of improved steel casting feeding rules was established based on the Niyama criterion determined from simulation. Newly developed feeding rules using this m...

In the casting process, in order to compensate for solidification shrinkage obtain higher dimensional accuracy of casting, it is often necessary modify original design castings, and a suitable compensation method has decisive impact on actual casting. this study, based simulation, reverse deformation proposed, two methods, empirical direct deformation, are implemented. The simulation results sh...
