Sažetak
Vertical centrifugal casting is used for casting of tubes where the diameter is larger than the length or it is used for cone shaped castings. Both non-cylindrical and asymmetrical parts can be casted using this process. Short tubes, slide bearings and smaller ring-shaped products are commonly casted. Simulation helps to understand filling and solidification process and casting parameters. A significant problem of vertical centrifugal casting is related to the solidification process. Using simulation software, which is based on the finite element method, it is possible to find optimal parameters and thus reduce the occurrence of defects. Also, using the software leads to significant savings on the production line, the production is more economical with better quality, extended product life and better mechanical and tribological properties of the castings. The main parameters that need to be defined are pouring rate, pouring temperature, mould temperature and rotational speed of the mould. Simulation of filling and solidification was carried out using ProCAST software to determine influence of parameters on final quality of stainless-steel casted tube. According to the results of simulation, rotational mould speed of 1400 rpm and the pouring temperature of 1510 ˚C are recommended.
