Computer simulation has a significant application in the field of metallurgy. It is primarily an issue that deals with the issue of casting. The simulation of casting and solidification makes visible the foundry phenomena that take place in the gating system and the casting when the mold is filled with liquid metal and during its solidification. The article deals with the design of the gating system and the simulation of the filling and solidification of a real casting made of ductile iron. In the next production ...

Computer simulation of foundry processes is an essential part of a modern foundry. The role of the gating system, its design and different elements are important in casting. Experimental verification of the designed gating system for new castings is costly, timeconsuming and economically inefficient. Therefore, these processes in the foundry are replaced by computer simulation. A detailed analysis of the simulation results makes it possible to predict various risks that may cause a failure in the quality of castin...

The purpose of this study is to identify relationships between the values of the fluidity obtained by computer simulation and by practically implemented tests. Three types of molds were used: 1. horizontal three-channel mold designed in the accordance with the methodology of the Measurement Systems Analysis which is useful for determining repeatability and reproducibility in the analysis, 2. vertical mold ? the lyre and 3. the spiral mold (Curry spiral). An aluminum - silicon - copper alloy was model material. The...

At present, increasingly high demands on the quality of the manufactured castings, which are used in the automotive industry. The foundry respect there are a number of advanced technologies, which are used for the casting. These include the technology of production castings by investment casting. It is used particularly where in view of the complex shape casting technology is the production of other more expensive, respectively, it is not at all possible. Such casting is the rotor of the turbocharger to be used in...

In a large competitive environment in which today foundry exist are more important is production of castings with high quality and high economic efficiency. Therefore, the use of 3D software and simulation programs is necessary in the pre-production stages. In them it is possible to design, construct and simulate filling and solidification of castings in the foundry mould, design ingate system and feeder system. A properly designed and calculated ingate and feeder system is the first prerequisite for producing of ...
